Faceplate MarkingsThese are the abbreviations that are used for the 8CSM/P+#C1470-#C1610-DM faceplate and their meanings.

DescriptionThe 8CSM/P+#C1470-#C1610-DM is a passive 8-port CWDM channel splitter and combiner module with upgrade port and monitoring port for dual power level monitoring. It is designed for bidirectional data transfer in dual-fiber linear add/drop and ring configurations.

The module allows access to the CWDM channels #C1270 to #C1450 or a sin-gle gray channel (#G1310) from a network fiber and splits/combines the CWDM channel set which ranges from #C1470 to #C1610.

The 8CSM/P+#C1470-#C1610-DM contains power splitters and a combination of specific add/drop optical filters as well as MUX/DEMUX filters. These filters perform the add/drop function on the pre-defined wavelengths and multi-plex/de-multiplex the eight CWDM channels #C1470 to #C1610 to/from the full duplex signal carried by the network fiber pair. The other eight CWDM channels of the spectrum or the gray channel are passed on to the upgrade port. The power splitters provide a facility for power level monitoring and optical spectrum analyzing. For this purpose, they drop 5% of the multiplexed/demultiplexed net-work signals to be passed on to the ingress/egress monitoring interfaces.

The module has eight bidirectional client ports, one bidirectional network port, one bidirectional upgrade port and one unidirectional monitoring port with two connectors (one for monitoring the ingress and one for the egress data signal power level).

On the client side, the 8CSM/P+#C1470-#C1610-DM works in conjunction with the corresponding channel modules. Table 173 on p. 841 lists the allocation of the client ports of the module to the individual CWDM channels.

The isolated gray channel is interfaced to an appropriate channel module. Con-necting the 1310-nm channel to the client equipment without using a channel module requires special attention.

Optionally, the power level of the incoming network signal and outgoing client signal may be monitored. The power level of the incoming (ingress) network sig-nal will be monitored, if the output connector Mon-D is connected to a power meter or OSA. If the output connector Mon-M is connected to a power meter or OSA, the power level of the outgoing (egress) client signal will be monitored.

This module is intended for use in an SH1HU/PASSIVE shelf only.

Features• Support of 16 channels (#C1270 - #C1610) according to ITU-T G.694.2

(20 nm wavelength spacing) and ADVA Optical Networking’s channel plan

• Power level monitoring of the incoming and outgoing network signals

• Front accessible LC type receptacle connectors

• Transport protocol independent

• Size: 5 HU high, 8 HP wide (2 slots)

Signal PathFigure 460 on p. 843 shows the operation of the 8CSM/P+#C1470-#C1610-DM and illustrates the signal path, which is described below.

* The input and output connectors of the client ports are not explicitly labeled on the faceplates.

CAUTION

If third party equipment with a wavelength of 1310 nm is connected to the 8CSM/P+#C1470-#C1610-DM, the operating organization of the network has to make sure that the output power of this equipment does not exceed the power limit of laser hazard level 1 as specified in IEC 60825. The operating organization is solely responsible for the laser safety of the end-to-end system.

PS

Note

As this module is completely passive, it is not visible in the inventory database. Therefore it is not supported by inventory management, the Control Plane or the Network Manager.

Figure 460: 8CSM/P+#C1470-#C1610-DM Operation Scheme

Receive DirectionThe 8CSM/P+#C1470-#C1610-DM receives a composite CWDM channel sig-nal through the input N-D of the network port from the far end of the link. In the direction of signal flow, the incoming network signal is split at the ratio of 95:5. 95% of the optical power is fed into the drop filter, and 5% of the optical power is fed into the output Mon-D of the ingress monitoring port. The drop filter drops the channel set #C1470 — #C1610 out of the composite CWDM channel signal and couples them into the DEMUX filter. The remaining the gray channel #G1310 or the channel set #C1270 — #C1450 is reflected onto the output U-D of the upgrade port for further de-multiplexing. The DEMUX filter in the splitter sec-tion de-multiplexes the set of CWDM channels into eight channels and couples them into single fibers to have the eight channels separate on the C1-D to C8-D outputs of the client ports. These channels are then transmitted to the corre-sponding CWDM channel modules.

Transmit DirectionThe 8CSM/P+#C1470-#C1610-DM receives the channels #C1470 to #C1610 from the corresponding channel modules through the inputs C1-M to C8-M of the client ports. The MUX filter in the combiner section multiplexes these eight individual channels into one channel signal and couples it into a single fiber. The add filter adds this combined channel signal in the direction of signal flow to the gray channel #G1310 or the eight blue band channels (#C1270 — #C1450) received through the input U-M of the upgrade port. The power splitter splits the resulting composite channel signal at the ratio of 95:5. 95% of the optical power is coupled into the output fiber and transmitted through the output N-M of the network port to the far end of the link. 5% of the optical power is fed into the out-put Mon-M of the egress monitoring port.
