The single-slot 32-Channel Demultiplexer (32DMX) card is an optical demultiplexer. The card receives
an aggregate optical signal on its COM RX port and demultiplexes it into to (32) ITU-T 100-GHz-spaced
channels. The 32DMX card can be installed in Slots 1 to 6 and in Slots 12 to 17.

32WSS-L Card-Level Indicators
Description
The red FAIL LED indicates that the card's processor is not ready or that an
internal hardware failure occurred. Replace the card if the red FAIL LED
persists.
The green ACT LED indicates that the 32WSS-L card is carrying traffic or
is traffic-ready.
The amber SF LED indicates a signal failure on one or more of the card's
ports. The amber SF LED also turns on when the transmit and receive fibers
are incorrectly connected. When the fibers are properly connected, the light
turns off.

COM RX port: COM RX is the input port for the aggregate optical signal being demultiplexed. This
port is supported by a VOA for optical power regulation and a photodiode for optical power
monitoring.
DROP TX ports (1 to 32): On its output, the 32DMX provides 32 drop ports (listed in
page 7-28) that are typically used for dropping channels within the ROADM node. These ports are
connected using four 8-fiber MPO ribbon connectors. The incoming optical signal to the
demultiplexer comes into the COM RX port. This input port is connected using a single LC duplex
optical connector.Each drop port has a photodiode for optical power monitoring. Unlike the two-slot
32DMX-O demultiplexer, the drop ports on the 32DMX do not have a VOA per channel for optical
power regulation. For a description of the 32DMX-O card, see the
on page 5-16.
