1.1 Alcatel DWDM systems

1626 LM : a scalable Alcatel DWDM platform initially developed for the Core network, for application from LH (Long Haul) to ULH (Ultra Long Haul). The 1626LM (Light Manager) provides a high transmission capacity on a single optical fibre by multiplexing up to 96x10Gb/s (STM64/OC192) channels on a 50GHz grid in the extended C-Band (1530nm to 1568.6nm) in Rel3.0 and 192x10Gb/s (STM64/OC192) channels on a 25GHz grid in the extended C-Band in future release. It can upgrade any existing DWDM link (see products below). The 1626LM can also be used for unrepeatered submarine systems.

1640 WM : a core Alcatel DWDM system supporting up to 160 channels in C+L Band (50GHz spacing) and working at different standard synchronous bit-rates from 2.5Gb/s to 10Gb/s.

1686 WM : a regional and metropolitan Alcatel DWDM system – scalable up to 32 channels in C Band –supporting different bit-rates from 100Mb/s to 10Gb/s. It can be upgraded to 72 channels (32 channels in C band and 40 channels in L band), with the use of the 1640 WM equipment for the L Band.

1696 MS : a cost-effective metropolitan Alcatel DWDM system supporting a broad range of data rates, easily customized for both non-amplified systems used for intra-city networks, or amplified systems for large metro networks. It is compact and scalable up to 32 channels.

1696 MS-C : a reduced-footprint version of the metropolitan DWDM 1696MS system for Customer Premises Equipment and edge applications that provides cost effective WDM networking functionality.

1692 MSE : a CWDM (Coarse WDM) equipment intended for the Metro Access, enterprise and Metro Core in small cities. It provides a cost-optimized, managed platform supporting different services and suitable for applications in diversified network topologies. The system can support up to 8 channels and can be configured as a Line Terminal or OADM (Optical Add Drop Multiplexer).

The extended C-band is divided into 12 bands of 8 channels maximum for a 50GHz channel spacing plan (from 1530.33nm up to 1568.57nm). This corresponds to the maximum capacity for a LH/ULH application (96 channels). The recommended band loading order with ALCT in band 5 is : band 7, 8, 6, 4, 9, 3, 2,10, 1,11, 12 and 5 (ALCT removed).

In an unrepeatered submarine system, we can use the first 10 bands (80 channels). The recommended band loading order with ALCT in band 5 is : band 10, 9, 8, 7, 6, 5 (ALCT removed), 4, 3, 2 and 1.

The communication between two adjacent WDM Network Elements is achieved via an “out-of-band” channel (Optical Supervisory Channel) at 1510 nm.

There are two main differences between the Back-to-Back Terminal and B-OADM configurations regarding the channels management :

� All channels can be added and dropped in a BtB Terminal where as some channels are “forbidden” in case of a BOADM configuration (1 channel lost in each band for a 50GHz channel spacing).

� Pass-through channels are fully optical in BOADM where as they are regenerated in BtB Terminal (two TRBD used).

� Pass-through channels are fully optical (no use of TRBD : cost reduction and higher reliability)

In addition, the add/drop configuration can be reconfigured remotely.

The incoming WDM spectrum is split in two parts in OADC1102 module. One part continues through WMAN1100 (“direct” wavelengths), the other part being dropped to BMDX1000. For each wavelength to be added in the ROADM - via CMDX and BMDX – the equivalent “direct” wavelength has to be blocked in WMAN1100 to avoid wavelength superposition into line when “added” and “direct” wavelengths are coupled via OADC1102.

The WMAN1100 is reconfigurable allowing flexibility in add / drop scheme. In a given band, some channels can be thus added/dropped and some others be bypassed without regeneration.

1686 WM - 10Gb/s 1686 WMTerminal

: legacy 1686 WM boards

: new 1626 LM boards

The 1686 WM is based on two mux/demux stages:

� the first one is made up of two OMDX boards, able to multiplex (or de–multiplex, because the boards are bi-directional) up to 16 chs each (one in red band, the other one in blue band) on a 100GHz grid.

� the second one interleaves the two resulting aggregate signals of 16 channels at 100GHz each to have one DWDM signal of 32 channels at 100GHz in C band (by means of the expansion board).

For the receiver side, the diagram is similar with Demux and without attenuator (Att.1 and Att.2).

This configuration allows to multiplex/demultiplex up to 32 channels to/from the DWDM line.

This upgrade is always possible, whatever the actual number “N” of installed channels. The remaining 32–“N” channels can be filled with 1626 LM transponders directly connected to the OMDX16 boards of the 1686 WM mux/demux scheme.

1626 LM transponders connected to the 1686 WM mux/demux and OADM’s for both upgrades andgreenfield (in this last case no 1686 WM transponders used).

The OADM repeater is made up of:

� line amplifiers, with the extraction/insertion of the OSC before/after the double–stage amplifier,

� OADM board, able to add/drop up to 4/8 channels per direction (east/west) according to the board type,

� transponders.

In upgrade installation, 1626 LM transponders, directly connected to the 1686 WM boards, can be added to the already installed 1686 WM OADM system.

In greenfield installation, the OADM structure is the same than the upgrade one but with only 1626 LM transponders.

This configuration is possible when only one 1686 WM Mux/Demux is installed (up to 16 channels), allowing the connection of the 1626 LM mux/demux to the unused port of the 1686 WM EXP board. Hence it is possible to increase the channels number to more than 32, filling the available band with 50GHz spaced channels.

The free band (Blue or Red) is filled with 1626 LM transponders at 50 GHz .

� Up to 36 (33) 1626 LM channels in the Red band for 52 (49) channels final system capacity with the +20 dBm amplifier (+17/+14 dBm amplifier).

� Up to 32 1626 LM channels in the Blue band for 48 channels final system capacity.

� The total link capacity is decreased when there are add/drop channels in the band populated with 1626 LM transponders and mux/demux: the channels 50 GHz spaced from the add/drop channels must be skipped for filtering issues (up to 8 channels skipped).

The advantage of this configuration is that one band is filled @ 50 GHz channel spacing and the total capacity is up to 52 channels (when Red band is upgraded with the 1626 LM transponders).

For the receiver side, the diagram is similar without attenuator (Att.1 and Att.2).

It is applicable to both upgrades and greenfields (no 1686 WM transponders in this last case).

The TCS scheme is based on 3 mux/demux stages (only the B&W to WDM direction is described):

� The first one is able to multiplex (or de–multiplex because the boards are bi–directional) up to 8 channels on a 200GHz grid (function supported by the TCS1xx, TCS302 and TCS401 boards).

� The second one can mix up to 5 aggregate signals of 8 channels to reach 40 wavelengths on a 100GHz grid (supported by the TCS302, Off–grid channels, and TCS401, On grid channels);

� The third one combines the two resulting aggregate signals of 40 channels at 100GHz to have one DWDM signal of 80 channels at 50GHz in C band (function provided by the TCS401 board).

The upgrade is allowed only when up to 40 channels of the 1640 WM system are installed.

Whatever the current number “N” of installed channels (40), all the remaining 80–“N” channels can be added with 1626 LM transponders + Mux/Demux (CMDX, BMDX).

The 1626 LM aggregate signal is connected to the unused input/output port of the 2:1 combiner/1:2 splitter of the TCS401 board.

The receiver side is similar without attenuator.

The upgrade configuration connecting directly the 1626 LM tributaries with the TCS boards is not allowed.

The MDX multiplexing architecture is based on two mux / demux stages:

� The first one is able to multiplex (or de–multiplex because the boards are bi–directional) up to 40 channels on a 100GHz grid; this function is supported by the MDX342 (On grid channels).

� The second one interleaves the two resulting aggregate signals of 40 channels at 100GHz to have one DWDM signal of 80 channels at 50GHz in C band (by means of the MDX441 board).

Whatever the current number “N” of installed channels the remaining 80–“N” channels can be filled with 1626 LM transponders directly connected to the MDX342 boards of the 1640 WM mux/demux scheme.

It is not allowed to upgrade an already installed 1640 WM system (with MDX441 and MDX342 boards) with the 1626 LM mux/demux scheme (instead of MDX343) connected to the MDX441 board.

There is no requirement for access to the rear for maintenance, so racks can be installed back-to-back. Each rack is equipped with a maximum of three sub-racks with a fan unit and an air filter located at the bottom ofeach sub-rack. All subracks are identical, fitted with different units depending on the subrack functionality. Power supply, fans, shelf controller and rack alarm interface units must be fitted to all shelves.

One shelf is declared as the “Master shelf” and the other shelves are declared as “secondary shelves”.

The shelf is divided into 41 slots.

Six different mechanics are available for the 1626 LM boards:

� 20 mm width, small height; this mechanic fits into slots 21, 22, 39 and 40.

� 20 mm width, medium height; this mechanic fits into slots 1, 2, 19 and 20.

� 25 mm width, small height; this mechanic fits into slots 23 to 38

� 25 mm width, medium height; this mechanic fits into slots 3 to 18

� 25 mm width, tall height; this mechanic takes two slots: one 25mm wide, medium height slot plus one 25mm wide, small height one which is under it. Thus, it fits in slots 3 plus 23, 4 plus 24 to 18 plus 38. The relevant units use the connector from the medium height slot to communicate with the SC.

� Double width, tall height (these boards are foreseen for future releases); this mechanic takes four slots : two adjacent 25mm wide, medium height slots plus the two 25mm wide, small height ones which are under them. I.e; it can fit in slots 5, 6, 25, 26. The units which have this mechanics use the connector from the left medium height slot (slot 5 in the above example) to communicate with the SC.

Each NE can be managed either locally through F interface with a Craft Terminal or remotely through Q3 interface with an Operation System. In latter case, the directly connected NE to OS (via a LAN or a DCN) is known as Gateway NE.

When connected to a NE via F or Q3 interface, it is possible to reach any other NE belonging to the same optical sub-system via two “out-of-band” Data Communication Channels, carried by the OSC :

• OMS-DCC terminated in terminals and OADM (3 bytes)

• OTS- DCC terminated in all equipment (9 bytes)

In addition to DCC, the supervision frame carried by the OSC can also transport one EOW (voice channel) and one 64kb/s auxiliary data channel.

At last, a User Data Channel at 2Mbit/s (G.703) between each NE is available for any purpose, carried also by the OSC.

1.2 1626 LM Equipment view

From 1320 CT or from the OS (1353NM & 1354RM), the “Equipment view” application (also called EML-USM) displays in graphical mode the NE hardware configuration such as defined in NE software database (Management Information Base): number of racks, number of shelves per rack, slot configuration, board view, port view. Alarm and administrative status are provided through the different “view” levels.

For instance, “Board alarm synthesis indicator” colour from Subrack view (as shown above) reflects the highest current alarm severity, regarding the “Equipment domain” alarms only.

When a board is “in service and locked”, no modification is enabled regarding the corresponding slot configuration. The board must be set “out of service” before any change (removal or modification of slot configuration).

The 1626 LM implements the OTN standard (specified in ITU-T G.709) to provide Operations, Administration, Maintenance and Provisioning functionalities to this DWDM platform. This recommendation –sometimes referred to as Digital Wrapper (DW) – takes single wavelength SONET/SDH technology a step further enabling transparent, wavelength manageable multi-wavelength networks.

2.1 G709 Framing

The implementation of the OTN Architecture in the WDM Equipment extends the transport control capabilities of the WDM optical channels.

OTN makes leverage on the transport layers defined in the OTH in order to provide:

� Mapping of a client signal of any rate (up to payload capacity) into containers at pre-defined bit-rates. This allows:

• To map a synchronous signal (SDH) into an asynchronous one (WDM)

• Client-independent networking

� Embedded associated overhead information for management and networking purposes (monitoring, support for complex connectivity, protections, alarms, etc.)

� Capability to support hierarchical multiplexing and concatenation

OTN (Optical Transport Network) architecture is defined in the ITU-T G.872 Recommendation, while the ITU-T G.709 Recommendation defines its interface in terms of Optical Transport Hierarchy (OTH)

The principles of this Architectures are implemented in Alcatel WDM Equipment starting from 1626LM Rel2.0.

> Optical Transport (channel) Unit

> Optical Channel

> Optical Multiplex Section

> Optical Transmission section

> OTM Overhead Signal

> Optical Supervisory Channel

> Optical Physical Section

In OTH the Optical Channel layer is further structured in layers:

� OPUk: Optical (channel) Payload Unit

� ODUk: Optical (channel) Data Unit

� OTUk: Optical (channel) Transport Unit

The index k specifies the signal rate supported, according to the following convention:

� K=1 represents an approximate rate of 2.5 Gbit/s

� K=2 represents an approximate rate of 10 Gbit/s

� K=3 represents an approximate rate of 40 Gbit/s

The OPUk, ODUk and OTUk layers are introduced in OTH in order to support the network management and supervision functionality through the contents of the additional signal overhead (OH) of the Units.

The Optical Channels, mapped to the OCC structure, are transported into an information structure named Optical Transport Module (OTM-n)

The OTM-n with full functionalities transports an additional overhead: the OTM Overhead Signal (OOS), containing overhead information related to the OCh, OMS and OTS sections.

The OSS information is mapped into a separate channel named Optical Supervisory Channel (OSC)

The index n in OTM-n specifies the number of OCC transported by the structure (not including the OSC).

OTM-n plays a role similar to STM-n in SDH architecture, the OCCs acting as tributary slots within the OTM-n architecture

The framing structure depicted above does not take into account the level 3 (k=3) corresponding to 40Gbit/s bit-rate.

First, client signal is mapped into an OPU-k by adding an Over Head. The OPU OH consists of the Payload Structure Identifier (PSI) which includes the Payload Type (PT) and overhead bits associated with the

mapping of client signals into the payload, like for example, the justification bits required for asynchronous mappings. The OPU OH is therefore terminated at the point where the OPU is assembled and disassembled.

ODU-k is then obtained by adding another OH to the OPU-k. The ODU-k OH consists of portions dedicated to the end-to-end ODU-k path and to six levels of tandem connection monitoring. The ODU-k path OH is terminated where the ODU-k is assembled and disassembled. The Tandem Connection OH is added and terminated at the source and sink of the corresponding tandem connections, respectively. Additional bytes provides two General Communication Channels (GCC1/GCC2) and Protection Communication Channels to manage Automatic Protection Switching at different levels (ODU-k path, ODU-k TCM, OTU-k section).

The OTU-2 frame structure is based on the ODU-2 frame structure by adding an OH and a FEC code. The overhead of OTU-2 is composed of a Frame Alignment Overhead (FA OH in the figure above) and an OTU-2 OH to support operational functions for transport via one or several Optical Channel Carriers (OCC). FA OH consists of a Frame Alignment Signal to detect the beginning of the OTU-2 signal and a Multi Frame Alignment Signal as OTU and ODU frames can span multiple OTU frames. The OTU-2 OH provides bytes for the Section Monitoring (Trail Trace Identifier, BIP-8…) and a General Communication Channel (GCC0).

The management system continuously monitors the quality of the signal flowing through various points in the system and accumulates this information during fixed time intervals in order to give a measure of the performance of the transmission system. The time interval can be selected to be 15 minutes, 24 hours or both, and the data for the current and some previous periods can be accessed. For each 15 minute PM point up to 16 history data are stored and for each 24 hour point up to 1 set of history data is stored.

Performance measurements include the number of corrected and uncorrected FEC errors and detection of loss of signal or loss of frame. These are synthesised into counters which are incremented over the chosen time interval.

At the FEC layer :

� BEC (Background errors corrected)

� SCS (Severely corrected seconds)

� BBU (Background blocks uncorrected)

� SUS (Severely uncorrected seconds)

At the SDH or SONET layer:

� ES (errored seconds)

� SES (Severely errored seconds)

� BBE (Background blocks error)

Thresholds for each counter can be set and an alarm is raised if the threshold is crossed during a monitoring period.

From the management interface it is possible to access PM data for the current and stored past time periods, activate, suspend, deactivate and reset performance monitoring, set PM counter thresholds and manage associated alarms.

The above figure represents all the external and internal monitoring points for input and/or output optical powers in transmission path.

The external monitoring points are accessible on the front panel of boards. They are suitable to connect an optical spectrum analyzer or an optical photometer for example. Signal provided at these external monitoring points comes from a tap coupler, corresponding to a few percentage of the real signal. We can note that there is no such test point on ALCT and OSCU boards.

The internal monitoring points provide from a tap coupler and after an analogue to digital conversion, an optical power measurement accessible from specific menus in CT or OS “Equipment View”. These “instantaneous measurements” do not concern only optical powers but also other parameters such as current unit temperature, laser bias current or laser temperature.

5.1 Local loopback

The “Local loopback” is also called “B&W line loop & continue”. The received client signal on the B&W interface is copied and sent back through the B&W emitter. This signal is also transmitted to the WDM emitter.

The behavior is the same for MCC30.




1 - 2 - 31


5.2 Remote loopback

The “Remote loopback” is also called “WDM line loop & continue”. The received signal on the WDM interface is copied and sent back through the WDM emitter. It is also transmitted to the User emitter.

The behavior is exactly the same for TRBC and MCC30.

MCC : Multirate Channel Card

MCC30 is a bidirectional transponder able to transport different kinds of bit-rate from 16Mbit/s to 2.66 Gb/s. It is equipped with one optical B&W interface and one non-tunable coloured (WDM) interface using 100 GHz channel spacing and featuring 12800 ps/nm dispersion accommodation (electro-absorption modulator).

The B&W optical interface is a Small Form factor Pluggable (SFP) module (see Section 3 – Appendix).

The supported bit-rates according to the available SFP modules on this board are :

• OTU1 (2.66 Gb/s)

• STM-16 (2.48 Gb/s)

• Gigabit Ethernet (1.25 Gb/s)

• Fibre Channel (1.062 Gb/s)

• STM-4 (622 Mb/s)

• STM-1 (155 Mb/s)

MCC30 can be configured either in MCC30_1 (pre_OTN) or MCC30_2 (no_OTN) :

• In pre_OTN mode (R3.0 – stand-alone shelf), the G.709 Frame and FEC are generated on board, but they are not SW managed (no access to OTU1/ODU1 overhead). User bit-rate is not configurable : STM-16 only.

• In no –OTN mode (R3.0A – stand-alone product), the MCC30_2 can be configured for all supported bit-rates above.

The board configuration can be “No cross--connection” (default configuration), “Add/Drop” or “pass--through”

(regeneration) thanks to a 8x8 matrix on board.

“Pass-through” configuration enables to send the received WDM signal on an adjacent MCC30 (also configured

in pass-through) through back-panel.

MCC30 can support 1+1 O-SNCP, loopbacks, and non intrusive B1monitoring for MCC30_1 only.

B&W side

The OCPU2104 contains optical components for inclusion into two separate ’B/W’ Client input and output paths, to and from 2 X two ’protected’ Transponders (called 1main, 1spare, 2main, 2spare). The OCPU2104 houses a pair of optical splitters that fit into the two ’TX’ paths, and two optical couplers that are fitted into two ’RX’ output paths from ’Protected’ Transponders.

Note : The above figure details only the sub-board 1 optical connections.

The 1x2 optical couplers/splitters fitted to the OCPU2104 have a nominal optical power splitting ratio of 50/50%, (where in the case of the splitters 50% of the applied optical power is fed to the ’Protected’ Transponder main, and 50% is fed to the ’protected’ Transponder spare), for use in a protection system with a 1+1 O-SNCP configuration.

In the “RX” direction, the OCPU2104 shall never receive both signals at the same time; the transponders whichare connected to it arbitrate among themselves in order to have one transponder B&W output active, and the other one in shutdown; by this mechanism it is not necessary to use a SWITCH on OCPU2104, but it is enough to use the coupler, always receiving at most one active input.

The coupler/splitter devices used in this unit are specified to operate at both client wavebands identified as1530-1565nm and 1290-1330nm. The 1x2optical coupler/splitters are specified to offer the lowest maximum insertion loss (2.7 to 3.9dB). The same device is used for both the coupler and splitter.

No alarm is raised by this module.

Wavelength Blocker

The Wavelength Blocker can be considered as an array of optical gates (such as Variable Optical Attenuators or Liquid Crystal shutters) and optical (on/off) switches placed between a Demultiplexer and a Multiplexer as schematically presented in figure above. It is thus able to selectively attenuate the single channels of an incomingmultiplex and even completely switch off selected channels. Note that device implementation of this optoelectronic function varies depending on providers.

The present release can manage 96 channels with 50GHz spacing in C+ band.

Each channel processed by the Wavelength Manager shall be in one of two possible states :• Express channels shall go through the WavelengthBlocker with a slight attenuation that shall be individually (i.e. on a per channel basis) set up (in a certain range) either by an operator or an algorithm/software process.• Blocked channels shall be blocked by the Wavelength Blocker i.e completely switched off.

ALC frequencies shall be Blocked in the WMAN board(s).

Whenever channel states are modified, the Optical Channel Monitor shall scan the output and input spectra in order to check that proper attenuations have been set up and proper wavelengths have been blocked.This verification shall also been carried out on a regular basis in order to keep up with any Wavelength Blockerdrift. The OCM can be also used to monitor signals from other boards through EXT_IN&1 and EXT_IN2 ports (not available in current release).

The dark VOA has two purposes :

• First it shall be used to insert an additional loss (offset) experienced by all channels in order to decrease the WB attenuation range employed, thus reducing the PDL and ripple of the latter.

• In addition, this normally turned off VOA shall shut down all traffic in case of a power failure (whereas most WBs are normally turned on / transparent without power supply) or board unplugging.

Feedback fordynamic ALCcontrol

The Optical Add & Drop Coupler (OADC1102) board covers Long Haul R-OADM specific needs.

This small height unit consists of one asymetric coupler and one asymetric splitter achieving passive add&drop for opposite directions as illustrated above. The coupler/splitter is broadband (whole extended C-band).

Regarding the signal coming from one pre-amplifier :• 30% are sent to express path (input of Wavelength Manager)• 70% are sent to drop path (input of first demultiplexing stage)

Regarding the signal outgoing to one booster :• 30% come from express path (output of Wavelength Manager)• 70% come from drop path (output of last multiplexing stage)

For Automatic Level Control purposes, on the add path the coupler shall achieve output power level measurement (express path + add path) and provide electrical feedback for ALCT Laser board if this one works in “dynamic” mode.

The OADC1102 is not managed by SW in R3.0A.

Output power from BMDX for ALC dynamic mode

ALCT1010 (Automatic Laser ConTrol) is used to to maintain a constant optical power over the whole extended C-Band, to facilitate the loading of the system with a few number of modulated channels or to compensate for the loss of some modulated channels. Typically one board per Line Terminal and 2 boards per OADM/Back-to-Back are used.

The ALCT1010 board can be used in 2 different configurations : Loading mode and Dynamic mode

In loading mode, the ALCT output power (the loop) is controlled via the electrical signal of the internal photodiode. The tuning is done with the OP_WDM_L provisionable parameter by the user or by the LALC algorithm. In that case, OP_WDM is the ALCT output power.

In Dynamic mode, the ALCT output power is controlled with a hardware loop from the BMDX output. In that case, the tuning is done with OP_WDM_D that is the BMDX output power target and that does not correspond to the ALCT output power. This loop control uses backplane links.

1626 LM loading plan

� ALCT1010 unit must be in band 5 and removed from the 88th channel,

� Channel loading order: 7, 8, 6,4, 9, 3, 2, 10, 1, 11, 12, and then 5 on G652,

� Channel loading order with 100GHz spacing : 7, 8, 6, 4, 9, 3, 2, 10, 1, 11, 12, 5 on G655 or tight link G652. Then, in the same band order the remaining channels are loaded.

Nevertheless, there are 11 versions of the ALCT1010 unit available for each of the bands 2 to 12.

As a function of the links or as a function of the segment of the link (BOADM case), the designer may have selected one of this unit to provide the ALC wavelength. In that case, a specific loading plan must be given in the LDT. In case of link with BOADM, the band related to ALC wavelength must never be in pass-through.

LOFA11y1 is a C-Band, dual stage, erbium doped fibre amplifier. It provides up to +17dBm output power and is used for regional application (32 channels max).

LOFA11y1 contains an internal tunable attenuator (VOA) in order to optimize the gain flatness during the life of the system and to avoid non linear effects in DCF. This VOA is floating meaning that it can be used or not via a front panel access, depending on the system configuration.

LOFA11y1 unit is capable to tune automatically its 1st stage and 2nd stage output powers by keeping the gain of each stage constant; this tuning mode is supported when the amplifier operates in unidirectional configuration as well as in Bidirectional configuration. The floating VOA is tuned by SW, not by the unit itself.

ESCT1000 (Equipment and Shelf Controller) is the hardware platform designed to support the Equipment Controller (EC) function and the Shelf Controller (SC) function.

The ESCT1000 board is in charge of the internal management of the node. It dispatches controls received by management system to the appropriate board, check consistency between expected configuration and the actual one and finally reports alarms, performance counters and measurements.

When the board is located in the Master shelf, both functionalities are optional and active. When the board is located in Slave shelves, only the SC functionality is provided.

The Flash memory must be plugged only in the ESCT1000 board plugged in the Master shelf.

The EC supports the Q3/TL1 Network Management agent and the VHM (Virtual Hardware Machine). It provides the HW resources (physical interfaces) and the SW functionalities (protocol stack) required for the communication between NE and Management system (OS, Craft Terminal, …).

The SC provides the resources to support the SW functions related to the physical machine control and management and configuration provisioning. In a shelf all the boards are connected to the SC via the SPI bus allowing the SC processor to collect the control information of the boards (e.g : alarms collection, remote inventory and data EEPROM reading).

64kbit/s

The Optical Supervisory Channel Unit carries supervision information from/to NEs by means of an additional 1510nm (OSCU101z) or 1565nm (OSCU102z) wavelength.

The OSCU board is used for the management of the supervisory channel composed of :

• a 2Mbit/s SuperVision Frame (SPV)

• a 2Mb/s User Data Channel (UDC)

The SPV is similar to the SDH section overhead (FAW, B1, E1, E2, F1, NU, D-bytes). It contains the LAPD communication protocol with the ESCT in the 12 Data Communication Channel bytes (D1-D3 for OTS / D4-D12 for OMS); furthermore the E2 byte carries a 64kbps voice channel dropped in a telephone handset through a jack connector (front panel) where as E1 byte carries a 64kbit/s auxiliary channel (coming from USIB1000 board).

OSCU must be used in conjunction with USIB1000 to provide external access of UDC.

OSCU10y0 provides 2 optical transmitters and 2 optical receivers enabling to supervise 2 directions (suitable to Line Repeater, OADM, B-t-B Terminal).

OSCU10y1 provides 1 optical transmitter and 1 optical receiver enabling to supervise 1 direction (suitable to Line Terminal).

In case of 1565nm wavelength use (for repeaterless submarine links), OSCU102z must be used in conjunction with a 1565nm insertion/extraction filter (declared as GNPU2000), installed in slots 3 to 18 (medium height), because LOFA11yz are only equipped with 1510nm insertion/extraction filters.

USIB1000 provides external access to :

• Two 2Mbit/s (E1) or 1.5Mbit/s (T1) User Data Channels (RJ45 connector)

• Two 64kbit/s auxiliary channels (RJ45 connector)

• An analogue audio interface (RJ11) to connect an external telephone desk set or phone extension towards other equipment.

These signals are adapted through embedded interfaces between OSCU board and external access.

T1 signals can be accepted on front panel but require in that case to be adapted in USIB in order to provide 2Mbit/s signals on the back panel, OSCU being only able to manage 2Mbit/s bit-rate for the UDC. The bit-rate selection is configured via a switch on USIB board (to position before installing the board).

A UDC pass-through in one NE must be done via external loop on USIB1000.

USIB is installed just under the OSCU board.

On back panel “dashed arrows” correspond to spare OSCU connections (not available in this release).

There are three 3 Audio in and out lines on back panel :

• First one for the main OSCU

• Second one for the spare OSCU (not available in this release)

• Third one for potential second USIB (not available in this release)

What : Safety procedure

Why : Human eye damage risk in case of fibre break due to high power

outgoing the device (≈ 20dBm)

Where : On LOFA

How : Automatic laser pump shutdown when LOS detected

Two cases : Line with and without OADM


Overview

The APSD complies with IEC 60825 1 & 2 and ITU-T G.664 recommendations.

Warning: always remove electrical power from near and far optical transmitters before disconnecting optical links between the transmitter and the receiver.

After the fibre cut in section 1, first stage of LOFA_W_E detects a LOS. As a consequence, this LOFA shuts down his first stage and then sends a shutdown command to the opposite LOFA (LOFA_E_W) through the back panel. Because there is no amplification anymore in Repeater towards the LT1, the signal received at LOFA_R_1 becomes very low (attenuated by sections 1 and 2). This very low level is considered as a LOS. Therefore, LOFA_R_1 acts as LOFA_W_E, shutting down his first stage and sending also a shutdown command to opposite LOFA (LOFA_T_1).

At the LOFA_W_E input, Optical Supervisory Channel and WDM channels are not detected because of thefibre cut in Section 1, causing the LOS alarm. At the LOFA_R_2 input, Optical Supervisory Channel and some power (noise) in the WDM window are detected, explaining the absence of alarm. But WDM channels were lost in section 1 due to the fibre cut that is why each Transponder raises a LOW alarm.

At the LOFA_R_1 input, power corresponding to the WDM window is below the acceptable level, because of the total shutdown of LOFA_E_W. Nevertheless, Optical Supervisory Channel is not impacted, being independent on amplification. As a consequence, LOFA_R_1 raises a LOMS alarm.

LOW on all TRBX

At the LOFA_R_2 input, we receive the added channels in OADM going through LOFA_T_E and the Optical Supervisory Channel. Assuming that the multiplex power is higher than the Degraded level, there is no alarm on this LOFA_R_2. Though channels coming from LT1 going to LT2 are lost in section 1, resulting in LOW alarms in all corresponding transponders of LT2.

Because of LOFA_T_W total shutdown, there is no acceptable WDM signal power anymore detected at the LOFA_R_1 input, the Optical Supervisory Channel being the only one signal detected, hence the LOMS alarm on LOFA_R_1.

This operation must be done on both WMAN1100 for each direction.




2 - 6 - 37


Configuring R-OADM

If the channel is blocked, the frequency front is in italic

The upper part of the window contains the “Wavelength Blocker” state (express or blocked) and attenuation for every channel of the 1626LM WDM grid (96 channels in extended C-band, 50GHz spacing). The attenuation shall be individually set up in a certain range either by the operator or an algorithm/software process (Correction process). Individual channel attenuation excludes WMAN insertion losses.

The “Commands for all” area enables to set/modify state and/or attenuation for all channels in one command with the same setting. These operation are performed by specific Wavelength Blocker optical components (see Section 1 – Module 3).

On bottom left, “Offset VOA” applies to the “Dark VOA”. When “VOA state” is not ticked, dark VOA is turned off meaning that dark VOA attenuation is set to maximum (40dB). Therefore all channels are “OFF”. Otherwise “Offset” value is applied to all express channels to reduce the use of individual variable attenuators in WB, thus decreasing the PDL and the ripple of these latter.

“Algorithms state” part enables to activate “Control” and “Correction” processes.

When WMAN board (re)starts, it can be with the default or the locally stored configuration (hardware switch). With “default configuration”, Dark VOA is “off”, Offset is at minimum value (1dB), all channels are “blocked” and all “algorithms” are disabled.

To change the configuration, from the “default” one, it is recommended to first enable the Correction process if desired, set “Offset VOA” (from 1 to 11dB) value, set channel attenuation (from 1 to 12 dB) and state (express or blocked), turn on Dark VOA and enable Control process if desired.

Whenever channel states are modified or Dark VOA is turned on, the board shall verify that instruction have been properly carried out. The input and output spectra shall thus be acquired and compared. The (background) Control process checks Dark VOA operation, blocked channels absence in output spectrum and express channels attenuation equivalence to the specified value within the accuracy range. Some alarms may be raised during this process. Control process if enabled apply relative attenuation equivalent to themeasured discrepancy.

As shown in the figure, the IP1 (1st stage input power) of the LOFA_T is the output on the BMDX board, which is in turn controlled and kept constant by the laser control circuit of the ALCT1010 board.

The ALCT1010 must be configured in “Dynamic mode” and the output power of the BMDX (i.e. the input power on the LOFA_T) must be set




2 - 7 - 11


2.2 Setting the output power in loading mode

1) In Equipment view, select the ALCT1010 board


3) Select the menu Board �� Optical power level configuration

The ALC & Optical power level configuration dialog box is

displayed.

4) Set the board output power by using the up and down arrows.

5) Click on Apply.

Wait a few seconds for the effective setting of the board. During this

process the command buttons of the dialog box are disabled.

6) Click on Close to finish.

ALCT1010 can operate in two modes :

� “Loading mode" where the operator directly sets the unit output power.

� “Dynamic mode " where ALC keeps BMDX mux at a constant output power level.

The principle of the Dynamic ALC is that ALCT output power is tuned in order to maintain BMDX-muxoutput power (which is constituted by the power emitted by the transponders and the ALC) at a provisioned level.

Preliminary condition :ALCT1010 needs to receive information from BMDX to be able to operate in Dynamic mode. Consequently, BMDX and ALCT1010 must be located in one of the following positions in the shelf : position of ALCT in dynamic mode




2 - 7 - 13


2.3 Configuring the board in dynamic mode [Cont.]

5) Click "Dynamic" in the “Mode Configuration" area.

6) In the Dynamic Alc Configuration area, enter the location of the

ALCT unit that must operate in Dynamic mode and click on Set.

7) In the "Power Configuration" area, set the BMDX mux output power

by using the up and down arrows.

Even if LOFA_T : Target Input Power is written, this parameter is the

BMDX mux target output power (the difference between LOFA input

power and BMDX mux output power does not exceed 0.5 dB).

8) Click on Set.

2.4 Activating SBS suppression

1) In Equipment view, select the ALCT1010 board


3) Select the menu Board �� SBS Suppression

4) Tick the operation you want to set : "enabled" to suppress SBS,

"disabled" to deactivate SBS suppression.

The purpose of ALCT1010 is to provide a dummy channel that optically loads the transmitted spectrum. ALCT stands for Automatic Level ConTrol.

Two parameters are provisionable on ALCT1010 :

� SBS suppression

� Output power level configuration

SBS : Stimulated Brillouin Scattering.

When SBS suppression is activated, a SBS modulation is added on the wavelength (low frequency modulation) in order to reduce Stimulated Brillouin Scattering.

• It is suggested to keep the default configuration: SBS suppression activated.

3.2 Procedure

Step 1 : IP1 (1st stage input power) setting of the LOFA_T (undir. LOFA) or of the bidir. LOFA by configuring the ALCT1010 board in dynamic mode

Step 2 : output power setting of the LOFA_T board

Step 3 : VOA attenuation setting

Step 4 : verify that the settings are correct by inspecting the “Instantaneous Measurement” on the LOFA_T board

Next steps: repeat steps 2 to 5 for LOFA_R (unidir.) or for other bidir. LOFA

Step 1 and 4 have been previously described

Step 2 and step 3 are explained in the following part of this presentation

1) In Equipment view, select the LOFA11yz board


3) Select the menu Board �� APT/VOA

The APT/VOA Configuration dialog box is displayed


3.3 Displaying the APT/VOA Configuration dialog box

N.B. : When LOFA11yz is Unidirectional, VOA is placed at the first stage output. When LOFA11y1 is Bidirectional, VOA is placed at the first stage input.

There are two main parameters to configure for LOFA11yz :

� The Automatic Power Tuning (APT)

� The Variable Optical Attenuator (VOA)

APT (Amplifier Power Tuning) modes :

•MANUAL: the 1st and 2nd stage output power is set at the value manually provisioned.

•POWER: Amplifier automatically controlled in Power (only for amplifier Unidirectional configuration). The 1st stage output power is automatically tuned according to the provisioned 2nd stage output power, to the measured VOA attenuation and parameters depending of the optical design of the link. This algorithm doesn't apply to 2nd stage whose output power remains manually tuned.

•GAIN: Automatic Gain control on first and second stage. Amplifier is controlled to keep its gain constant on the two stages. It is therefore required that a link can be upgraded without ALCT unit but with an automatic tuning of the line amplifiers.

VOA modes :

•MANUAL: VOA is set at the value manually provisioned.

•MSV: Mid Stage VOA tuning (only for amplifier Unidirectional configuration); VOA is automatically tuned according to the LOFA input and output powers in order to control and optimize its spectral flatness.

•SAC: Span Attenuation Control (for amplifier Unidirectional and Bidirectional configurations); VOA is set according to the 1st stage input power, to the estimated end of life span attenuation and to the number of channels amplified by the 1st stage gain block at installation.

3.5 Step 2 : output power setting of LOFA11yz : APT

1) Provision the APT mode in the APT area.

� If Manual mode selected: provision the 1st and 2nd stages Output Power,

OP1 and OP2 fields

� If Power mode selected : provision OP_Diff and the 2nd stage output

power OP2 fields

� If Gain mode selected : provision EOLspan and IT fields

2) Click on Apply after each modifications. Wait for a few seconds for

the effective setting of the board. During this process, the command

buttons of the dialog box are disabled.

3) Click on Close to terminate.

Provisionable parameters : according to the selected APT mode, some fields are provisionable using the up and down arrows, and the others are greyed (not provisionable).

OP1 : Output Power of 1st stage

OP2 : Output Power of 2nd stage

OP_Diff : is the difference between the line fibre input power (OP2) and the Mid-Stage payload input power (post VOA first stage output power). Default value is 9 dB.

In “Power” mode, OP1 is automatically tuned to optimize the LOFA1 OSNR contribution according to OP_Diff and OP2 parameters. Amplifier output power (OP2) is constant. In case of LOFA11y1 Bidirectional, “Power” mode is not supported.

In “Gain” mode, OP1 and OP2 are returned in function of their input. Both amplifier stages are indeed controlled in gain (constant gain).

3.7 Step 3 : VOA attenuation setting

For Unidirectional LOFA

1) Provision the VOA mode in the VOA area.

� If Manual mode selected: provision the VOA attenuation

� If MSV mode selected : provision K_Diff

� If SAC mode selected : provision K_Diff and EOLspan





Provisionable parameters : according to the selected APT mode, some fields are provisionable using the up and down arrows, and the others are greyed (not provisionable).

Compatible APT modes are :

• Manual or Power for Mid-Stage VOA mode

• Manual or Gain for Span Attenuation Control mode

K_Diff : is the difference between the theorical flatness constant (K_theoric) (=31dB for LOFA111z and 37 for LOFA112z) and the effective constant (K_flat) according to which the LOFA tilt must be adjusted. Default value is 0dB.

K_flat = K_theoric + K_diff = OP2 – IP1 [effective amplifier gain] + OP1 – IP2 [Mid-stage Loss ]

EOLspan : End of Life attenuation of the span. This value is estimated. This represents the attenuation between the upstream node where channels are added and the first stage input.

In case of MSV mode, VOA attenuation is tuned so as to optimize the amplifier flatness, according to the effective amplifier gain, the mid-stage Loss and K_Diff.

In case of SAC mode, VOA attenuation is tuned so as to optimize the amplifier flatness according to theEOLspan.

� If Manual mode selected: provision the VOA attenuation

� If SAC mode selected : provision N1, Pch1 and EOLspan





Provisionable parameters : according to the selected VOA mode, some fields are provisionable using the up and down arrows, and the others are greyed (not provisionable).

The MSV mode is not supported (“floating” VOA is placed at first stage input).

N1 : number of channels amplified by the first stage (Receive side) at installation.

Pch1 : Power per channel at first stage input at installation.

In SAC mode, VOA attenuation is tuned so as to maintain the input power constant.

The performance monitoring is supported at the following layers :

� SDH Regenerator Section (RS) layer, both for STM-16 and STM-64 signals,

� FEC layer.

For the SDH-RS layer, the following performance counters are supported:

� Erroneous Second (ES): Count of seconds with at least one B1 code violation or with at least one RS defect.

� Severely Erroneous Second (SES): Count of seconds which contains more than 2400 ( approximately > 30%) B1 code violation, or at least one RS defect. A SES is also counted as an ES.

� Background Block Error (BBE): Count of B1 code violations that do occur out of a SES.

For the FEC layer, the following performance counters are supported:

� Background Error Corrected (BEC): count of FEC corrected errors that occurred outside a SCS (result is divided by 512).

� Severely Corrected Seconds (SCS): count of seconds with a FEC layer defect or at least one FEC uncorrected block or more than 33 538 048 FEC corrected errors.

� Background Block Uncorrected (BBU): count of FEC uncorrected blocks that occurred outside a SUS.

� Severely Uncorrected Seconds (SUS): count of seconds in which a FEC layer defect occurred or in which more than 33 538 048 FEC blocks were uncorrected.

2.2 Line Terminal #1 (1/2)

System configuration :

• There are 3 bands : Band 2, Band 7 and Band 12

• Bands population :

� Band 2 : 5 channels -> 5 TRBD

� Band 7 : 3 channels (channel 33 is not used here) -> 3 TRBD


• For each Band a CMDX is needed then 3 CMDXs are to be used.

• 1 BMDX is needed. We use BMDX1000 because it is a Line Terminal.

• 1 OSCU is needed. We have one direction to manage.

• Transmitted channels are less than 88. Then one ALCT is to be used in order to maintain the input power of LOFA in the correct range of values.

• Guide lines for LT1 configuration

� Hardware configuration must be scalable for future extension. That’s why, TRBD have to be inserted in order of channel number (i.e 32.5, 33, 33.5) from the farest to the nearest to CMDX leaving empty slots for TRBD not yet used.

� In master shelf, we put boards for control (ESCT), LOFAs, BMDX, OSCU, ALCT in suitable slots . There are 11 empty slots (11:18) where we insert TRBDs.

� CMDX of the BAND served in master shelf is inserted in slot 19. In this way there is only 1 pair of fibre that goes through the rack (from CMDX to BMDX)

� Channel 51.5 is the second in Band 2, then the slot after LOFA T in Master Shelf is empty to maintain TRBDs in order of frequency from the higher to the lower from the nearest to the farest from CMDXs

� In the slave shelf we have 16 slots to insert TRBD. There are 12 TRBDs to insert: 5 for Band 2, 3 for Band 7 and 4 for Band 12. Conventionally, we insert TRBDs of band 2 in the master shelf, the others in the slave one.




3 - 1 - 11


2.3 OADM (1/2)


B12 pass through

• Channels from 3 bands are received.

� Band 12 is in pass-through then CMDXs and TRBDs are not necessary for this band.

� In Band 2, 2 channels (i.e 53.5, 54 ) are terminated, other 3 ones (i.e 53, 52, 51.5) go from one side to the other. Then we need 2 CMDX, 2 TRBDs for the terminated channels and 2 TRBDs for each channel to regenerate.

� In Band 7, there are 2 channels (i.e 32.5 and 33) terminated in one direction, 1 channel in pass-through (i.e 32) and 1 channel (i.e 31.5) that is terminated from both directions.

• For Band 7, we need 6 TRBD

� 2 channels terminated from one direction -> 2 TRBD

� 1 channel regenerated -> 2 TRBD

� 1 channel terminated from both directions -> 2 TRBD

• For Band 2, we need 8 TRBD (2 + 3 x2)

• CMDX needed are 4 totally (2 bands added/dropped in two directions).

• 2 BMDX1100 are used because it's a OADM.

• Channels globally used are less then 88 then 2 ALCT are necessary, one for each direction.

• 2 directions are to be controlled then both channels of OSCU are needed

• 2 LOFA for each side are needed




3 - 1 - 12


2.3 OADM (2/2)



• OADM Master shelf guide lines

� All the boards that permit NE to work (ESCT, PSUP), Mux/Demux for both sides (6 boards globally), OSCU and ALCTs, LOFAs for both sides (4 boards totally) are inserted here.

� CMDXs are inserted in the slots 2 and 19.

� TRBD with highest frequency is inserted near CMDX, TRBD with lower frequency is insert on its left and so on.

� 7 slots are free and useful to insert TRBDs.

� 8 TRBDs are needed for Band 2, 6 for Band 7. For this reason, TRBDs for Band 7 are inserted here.

� No free slot is maintained between TRBDs 32 and TRBD 33.

� No other frequency of Band 7 will be used . Then no other TRBD will be inserted in Master Shelf.

• OADM slave shelf guide lines

� 16 slots (3 to 18) are free and useful to insert TRBDs.

� For Band 2, 8 TRBDs are needed.

� Order of frequencies is maintained when inserting TRBDs in the shelf.

� TRBDs are inserted so as to respect the order of frequencies. Some slots are left empty for future channels in Band 2 (not yet used).




3 - 1 - 13




• There are 3 bands : Band 2, Band 7, Band 12.

� Bands population :


� Band 7 : 3 channels (channel 32.5 is not used here) -> 3 TRBD


� For each Band a CMDX is needed then 3 CMDXs are to be used.

� 1 BMDX is needed. We use BMDX1000 because it is a Line Terminal.

� 1 OSCU is needed. We have one direction to manage.

� Transmitted channels are less than 88. Then one ALCT is used to maintain the input power of LOFA in the correct range of values.




3 - 1 - 14





• LT2 Master shelf guide lines

� Globally there are 10 TRBDs to be provisioned.

� 6 slots are occupied by ESCT, BMDX, OSCU, ALCT and LOFAs.

� It is fixed to serve only 1 Band in Master Shelf, leaving space for future provisioning.

� Band 2 is served here (3 TRBDs are necessary).

• LT2 Slave shelf guide lines

� 2 Bands, 7 TRBDs.

� TRBDs are provisioned in order of frequency from higher (nearer CMDX) to lower.

� Slots for not used frequencies are left empty.
