14.7.6 32WSS Card
A ROADM network element utilizes two 32WSS cards (two slots each) and two 32DMX cards (one slot
each), for a total of six slots in the chassis. For a diagram of a typical ROADM configuration, see
"ROADM Node" on page -8. The 32WSS card can be installed in slots 1-2, 3-4, 5-6, or in slots 12-13,
14-15, or 16-17.
The 32WSS has six types of ports:
•
•
•
•
•
•
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.

ADD RX ports (1-32): 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.
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 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 pre-amplifier 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.
