FTTx-Solutions
The consistent use of optical fibres up tothe subscriber instead of installingseparated networks for voice, data andvideo facilitates the implementation of auniversal Triple Play network for allthree services. This is the most future-proof solution for the transmission of100 Mbps without any distance pro-blems.
In particular point-to-point systems pro-vide the highest degree of future-proof-ness for FTTH (Fibre-to-the-Home)connections. Currently switched FastEthernet is the solution of choice provi-ding each subscriber with a P2P conn-nection at data rates of 100 Mbps. Thecentral components and the CustomerPremises Equipment (CPE) made byNexans have specifically been designedfor this purpose. Moreover, the NexansCPE offers a special technology for theefficient multicast transmission of Videoover IP, ports for connecting traditionaltelephones (POTS) as well as particular-ly high security and data integrity.
Unlike shared technologies, such astree-structured passive optical networks(PON), Ethernet can be used to deployscalable networks at data rates up tothe gigabit range without changing theinfrastructure.
Active components for FTTxFTTx networks i.e. Fibre-to-the-Home,Fibre-to-the-Curb, etc. have a rathersimple infrastructure. Network opera-tors setup a data network within ametropolitan area which is similar tothe networks of large companies.
High-performance data switches areinstalled at strategic points and inter-connected via singlemode fibre-opticcables. Gigabit or 10 Gigabit Ethernetwill be used for transmission. From herethe subscriber is connected eitherdirectly via 100 Mbps or remote swit-ches with Gigabit Ethernet uplinks areused as an intermediate stage. Theinstalled switching and routing equip-ment is fitted with optical connections inthe uplink and with 100 Mbps or 1Gbps copper ports on the subscriberside. Media converters convert thecopper ports into single or dual fibresinglemode ports. For the developmentof areas with a higher subscriber densi-ty Nexans offers wavelength divisionmultiplexing systems (WDM) based on
Coarse WDM (CWDM) and DenseWDM (DWDM) technologies.Connectivity to customers in apartmentand single-family houses is implemen-ted as follows:
Single-family houses are equipped withoptical single or dual fibre access. Thecable is terminated for instance in a ter-minating unit in the basement. Hereboth passive and active network termi-nations are located. The passive partprovides the termination of the opticaloutdoor cable and usually contains asplice cassette for accommodating an
optical connector providing the connec-tion to the active network termination, i.e. the Customer Premises Equipment(CPE). On the subscriber side theNexans CPE is equipped with 4 and 8Fast Ethernet switch ports respectivelyand 2 tip-and-ring (TR) POTS ports. Themechanical design of the Nexans FTTHsolution provides some special advan-tages with a view to the minimization ofinstallation costs, the efficient marketingof broadband access lines and a highoperational security based on an opti-cal plug-in connection without opticalconnection cable.

Nexans CPE there is a fixed opticalconnector on top of the passive networktermination unit. The active part is sim-ply plugged-on by the customer (Fig. 2).
Splitting the CPE into an active and apassive part offers the special advanta-ge that first of all it is possible to installall passive network terminations in onego when developing an area. If thecustomer now orders a connection, hewill receive his active CPE part by mailand simply plugs it on himself. Now theCPE automatically sets up a connectionto the central office, receives its custo-mer-specific configuration from there,and is immediately operational, thuseliminating the need of sending out atechnician to the customer. In this waynot only the costs for commissioning theequipment can be saved, moreoversales strategies can be employed wherethe customer has the possibility oftesting the services for a limited trialperiod.
In particular IP-TV offers a multitude ofadditional services and revenue stre-ams. For example Time-Shift TV allowsthe time-shifted provision (by max. 24h) of video on the central video server.The personal video recorder offers thesubscriber the possibility of centrallystoring several programmes from diffe-rent channels at the provider.
The economical operation of the CPEs
requires comprehensive managementand configuration features.Prioritisation is necessary to guaranteethe Quality of Service (QoS) in TriplePlay networks. Additionally specialmeasures are needed to support strea-ming video in IP multicasts. Security andauthentication features, granting accessonly to those users with the correctequipment address and with the appro-priate authorization stored on a centralserver, play a particularly importantrole.
In-house mostly copper cables are usedtoday. However, in the future plasticoptical fibres (POF) will be an alternati-ve.
In apartment houses each family canhave their own optical access. Thecable is either fixed or blown-in. In theapartment there is the Nexans CPE offe-ring the subscriber 100 Mbps TwistedPair interfaces for Triple Play and tele-phone, while the optical fibre is sealedin the equipment inaccessible to thesubscriber.
The use of CPEs with 4 and 8 FastEthernet ports respectively in the apart-ments simplifies and accelerates the ter-mination of the fibre-optical cable andthe conversion into data interfaces. Thiseliminates the need for externalmodems or switch systems with theirassociated fans etc.
For apartment houses with in-housecopper cabling a small 19" cabinet or awall enclosure is used to accommodatethe systems. In order to minimize capi-tal costs, standard Twisted Pair (TP) dataswitches with for example 24 TwistedPair interfaces are installed. The apart-ments are connected via Twisted Paircables. The installation of a CPE with aTwisted Pair uplink in each apartmentallows the customer to use up to 8Ethernet/Fast Ethernet ports.
Nexans believes that Ethernet access inan apartment offers the advantage thatthe customer is able to connect anycommercially available terminal whichhas a standardised Ethernet interface.
The comprehensive management featu-res for central configuration, line moni-toring and bit-rate billing offer the ope-rator the tools needed for a cost-effi-cient and profitable operation of hisnetworks.
As an option the CPE-systems are alsoavailable with an integrated CATV-bro-adband module (862 MHz).
In order to enhance the availability forsensitive applications, specially desi-gned, uninterruptible power supply(UPS) systems complete the CPE productportfolio.
