and typically connect to transponder modules in colocated equipment. The MON port
allows you to monitor the composite signal at the output of the multiplexer and at the
input to the demultiplexer.

C-Band
In the line-in direction, the incoming C-band channels from the L1 port are demultiplexed
into individual wavelengths for output onto the respective client ports.
In the client-in direction, the individual C-band channels are multiplexed onto a composite
signal for output on the L1 port.
OSC
The FMD96 does not process the OSC signal from the attached ROADM module. Instead,
the FMD96 demultiplexes the OSC signal from the composite signal on the L1-In port
and multiplexes it back into the composite signal for output on the L1-Out port. This
allows the connected ROADM module to detect the presence of the FMD96 if applicable.
