7.11.1 40-WSS-CE Faceplate Ports
The 40-WSS-CE card has eight types of ports:
• ADD RX ports (1 to 40): These ports are used for adding channels. Each add channel is associated
with an individual switch element that selects whether an individual channel is added. Each add port
has optical power regulation provided by a VOA. The five connectors on the card faceplate accept
MPO cables for the client input interfaces. MPO cables break out into eight separate cables. The
40-WSS-CE card also has one LC-PC-II optical connector for the main input.
• COM RX: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE)
and sends it to the optical splitter.
• COM TX: The COM TX port sends an aggregate optical signal to a booster amplifier card (for
example, the OPT-BST card) for transmission outside of the NE.
• EXP RX port: The EXP RX port receives an optical signal from another 40-WSS-CE card in the
same NE.
• EXP TX: The EXP TX port sends an optical signal to the other 40-WSS-CE card within the NE.
• DROP TX port: The DROP TX port sends the split off optical signal that contains drop channels to
the 40-DMX-C card, where the channels are further processed and dropped.
Figure 7-30 shows the 40-WSS-CE card faceplate.
