16.7.6 32WSS Card
The 32WSS has six types of ports:
• ADD RX ports (1 to 32): 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 32WSS has four physical receive connectors
that accept multifiber push-on (MPO) cables, which break out into eight separate cables, on its front
panel for the client input interfaces.
• EXP RX port: The EXP RX port receives an optical signal from another 32WSS module in the same
network element.
• EXP TX port: The EXP TX port sends an optical signal to the other 32WSS module within the
network element.
• COM TX port: The COM TX port sends an aggregate optical signal to a booster amplifier card (for
example, OPT-BST) for transmission outside of the network element.
• COM RX port: The COM RX port receives the optical signal from a preamplifier and sends it to the
optical splitter.
• DROP TX port: The DROP TX port sends the split off optical signal that contains drop channels to
the 32DMX card where the channels are further processed and dropped.
A terminal site can be configured using only a 32WSS card and a 32DMX card plugged into the east or
west side of the shelf.
Figure 16-51 shows the 32WSS module front panel and identifies the traffic flow through the ports.
