    1 GENERAL 1.1 Introduction to the equipment The Alcatel 1626 Light Manager (1626 LM in the following) is the new platform of Dense Wavelength Divi- sion Multiplexing (DWDM) systems for Core Networks. The Alcatel 1626 LM addresses terrestrial applications from Long–Haul (< 600 km) to Ultra Long–Haul (up to 4500 km) and unrepeatered submarine applications (400 Km single span), from average capacity for regional networks up to large capacity for pan–continental networks (up to 192 wavelengths).

  • Page 59: Line Terminal (Lt)

    1.2.1 Line Terminal (LT) In Line Terminal configuration (LT), the 1626 LM connects, according to the system architecture, – up to 96 x 10Gbps B&W client signals, with TRBD using, or – 384 x 2.5Gbps B&W client signals, with TRBC using to an optical fibre DWDM line.

  • Page 60: Line Repeater (Lr)

    1.2.2 Line Repeater (LR) In Line Repeater configuration the 1626 LM is a bidirectional DWDM amplifier without transponder nor MUX/DEMUX functions. The line repeater consists of two optical double–stage in–line amplifiers (providing a bidirectional DWDM amplifier) in order to boost the optical power of the aggregate WDM signal avoiding channels demux and regeneration (no optical to electrical conversion).

  • Page 61: Optical Add And Drop Multiplexer (Oadm) Repeater (Or)

    1.2.3 Optical Add and Drop Multiplexer (OADM) repeater (OR) The OADM repeater is a Line Repeater with the capabilities to add and drop one or more wavelenghts to/from the aggregate signal in both directions. Up to 100% of the wavelengths (12 bands) can be added/dropped. All the bands that are not extracted are in complete pass–through, without any regeneration.

  • Page 62: Back To Back Terminal (Bt)

    1.2.4 Back to back terminal (BT) The back to back terminal is a single NE grouping two line terminal configurations giving the capability to address both East and West direction of a link/ring. It has both add and drop and 3R regeneration capabilities. Up to 96 channels/wavelengths (12 bands) are added/dropped or regenerated in current release.

    In the next block schemes, only Tributary Direct Transponders (TRBD) with one 10 Gbps B&W client signal and one coloured 10 Gbps signal, are taken into account. From current release is also available the Tributary Concentrator (TRBC) with 4 x 2.5Gbps B&W client signals and one coloured 10Gbps sig- nal but it is not shown in the following figures, for semplicity reason.

    Figure 22. shows the upgrade scheme with the MDX401 mux/demux scheme. Whatever the actual number “N” of installed channels the remaining 80–“N” channels can be filled with 1626 LM transponders directly connected to the MDX3xx boards of the 1640 WM mux/demux scheme. It is not allowed to upgrade an already installed 1640 WM system (with MDX4xx and MDX342 boards) with the 1626 LM mux/demux scheme (instead of MDX343) connected to the MDX4x board.

    1.3.1.2 Line terminal equipment built–up of 1626 LM and 1686 WM Hereinafter, a brief description of the 1686 WM mux/demux scheme is given. It 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 bidirectional) up to 16 chs each (one in red band, the other one in blue band) on a 100GHz grid –...

    Figure 25. shows the 1686 WM upgrade scheme with the 1626 LM mux/demux scheme connected to the expansion board of the 1686 WM. This configuration is possible when only one 1686 WM Mux/Demux is installed (up to 16 chs), allowing the connection of the 1626 LM mux/demux to the unused port of the 1686 WM EXP board.

    4.3.3 OSCU1010 (Optical Supervisory Channel Unit) The OSCU board is used for the management of the supervision channel, transported over a 1510nm ex- tra–band wavelength with a 4.864 bit rate being the result of the multiplexing of two 2.048 Mbps streams: the 2 Mbps OSC frame and the 2 Mbps service channels (UDC, future rel.).
  • Page 194 The supervisory channel path is bidirectional. At first, the 4Mbps signal (OSC + UDC) on a 1510 nm wavelength, is extracted from the optical aggregate signal with an optical filter, in amplifier or mux/demux board. Then it is received by the OSCU board and electrically demultiplexed in two 2 Mbps streams: the 2 Mbps UDC stream and the 2 Mbps OSC stream.
