The two-slot 32-Channel Wavelength Selective Switch (32WSS) card performs channel add/drop
processing within the ONS 15454 DWDM node. The 32WSS card can be installed in the following pairs
of slots:
7.3.1 32WSS Faceplate Ports
The 32WSS has six types of ports:

ADD RX ports (1 to 32): These ports are used for adding channels (listed in
Each add channel is associated with an individual switch element that selects whether that channel
is added. Each add port has optical power regulation provided by a variable optical attenuator
(VOA). The 32WSS has four physical receive connectors that accept multifiber push-on (MPO)
cables on its front panel for the client input interfaces.Each MPO cable breaks out into eight separate
cables.
EXP RX port: The EXP RX port receives an optical signal from another 32WSS card in the same
network element (NE).
EXP TX port: The EXP TX port sends an optical signal to the other 32WSS card within the NE.
COM TX port: The COM TX (line input) port sends an aggregate optical signal to a booster
amplifier card (for example, OPT-BST) for transmission outside of the NE.
COM RX port: The COM RX port receives the optical signal from a preamplifier (such as the
OPT-PRE) and sends it to the optical splitter.
DROP TX port: The DROP TX port sends the split-off optical signal containing drop channels to
the 32DMX card, where the channels are further processed and dropped.
