Management system • Stand alone, HTML web interface• SNMPv1 for alarm notification

16ALM/PTP/-48VDC

ALM Monitoring Unit4

• HW is based on the ALM16, both AC and DC should be available at the same time

• Performance comparison with ALM16• Dynamic range is slightly lower (~2dB) because of higher insertion loss 1x64

switch• Scanning speed of ~4 minutes for all 64 ports (in an Access Network). Priority

ports can be defined for faster scanning speeds

R2.3 – 64-port ALM (ALM64)5

3G/4G USB dongle for remote DNC access6

• On some sites a DCN might not be available. Remote access can be realized to an ALM in that case by using a 3G/4G Dongle

• The following dongles are currently under test:• ZTE MF823• D-Link DWP-157• Huawei E3372 4G LTE

• Note: it is uncertain yet which of these dongles are going to be included in the release

• ADVA does not resell the dongles. Customers are to purchase the dongles directly

USB Dongle is connected to MGMT port

• 1HU shelf with 16 integrated WDM Couplers• Only one 16/1CSM/1HU+#1650 module

required per ALM Monitor Unit.• 16 LC/APC cables are required to connect

the ALM Monitoring Unit to the shelf

• Ruggedized Y-cable with an integrated WDM Coupler • Per ALM port a Y-cable needs to be used

(up to 16 cables per ALM monitor unit)

Coupler Shelf

ALM Coupler Options7

A 32x WDM Coupler shelf will be developed in 1RU with LC/PC connectors. In essence this is the same as the 16x WDM Coupler shelf, but then at double the density.

ALM Connections Data in Data out

32x WDM Coupler (32/1CSM/1HU+#1650)8

• 8-channel WDM Coupler to be mounted next to ALM16• Standard ALM16 mounting brackets can be used• Mountable in 19”, 21” and 23” racks• Ideal for use with non-ADVA DWDM Transmission systems where the

required port count is typically not very high

8x WDM Coupler9

• Single demarcation reflector packaged in a stub enclosure with 310 cm fibers and LC connectors

• A demarcation reflector needs to be used per ALM(up to 16 cables per ALM monitor unit)

• Industrial Temperature Component (-40°C … +85°C)

• Pluggable SC enclosure (the same enclosurecommonly used for attenuators)

• A demarcation reflector needs to be used per ALM(up to 16 cables per ALM monitor unit)

• Industrial Temperature Component (-40°C … +85°C)

Performance Fingerprint/Fault Analysis13

• In CO propagating the total launch power limited to a fixed 14 dBm.• In COUNTER propagating launch power can be higher if the span is long

enough.• Please refer to dedicated slides on DWDM power limits for more details

• What is it?New reflector in an LC/APC plug form factor

• Reason for introduction:Pluggable reflector that can directly be connected to the AUX port of the OSFMA and newer amplifiers with internal ALM couplers.

• Supported wavelengths:Reflects full c-band so can only be used in combination with coupler or for cable monitoring, can not be used as reflector with data passing trough it.

Note: Has a simplex fiber connector so you need two if you want to reflect both fibers of the duplex AUX port

• Human readable email format• Initial email implementation of the ALM was XML-format only• Some customers want to receive human readable emails• Email type to be sent can be configured in the ALM GUI

• SMS capability• In addition some customers request SMS notification• In order to send an SMS an “email-to-SMS” gateway is needed• Many gateways exist (some for free, some for a low fee)

ALM Operation Modes18

Management ALM (Examples)19

• In R2.3 fiber faults are detected automatically in bi-directional operation using a central NTP clock for synchronization

• The ALMs take turns measuring co/counter propagating fibers

NTPTimeslot 1 (15min)

Timeslot 2 (15min)

Timeslot 115min

Timeslot 215min

Timeslot 115min

Timeslot 215min

• A cable cut will cut both transmission fibers and thus will regardless of the timeslot be detected

GIS: Geographical Information System

• GIS integration with Cocon and NetGEO has been realized through a REST interface

• Please refer to the dedicated slidedeck on Cocon for more information

Connection verification Link verification Fault identification

GIS Integration: Cocon and NetGEO25

OSPInsight orConnectMaster

• OSPInsight support is present since ALM release R1.4

• In R2.1.1 support of ConnectMaster is added. It should be noted that ConnectMaster verified the Email functionality of the ALM16, but still has to do some work to complete integration on their end.
