21 dBm gain flattened high gain EDFA
EDFA modules are single-wide, single-output devices. Each module is connected to
one input fiber and one output fiber through optical fiber connectors on the side of
the module housing. The modules can be mounted in either receiver or transmitter
slots on the optical interface board in the node lid using a reversible pin adaptor. The
pin adaptor is used to adapt the module to the connector arrangement for a
transmitter slot or a receiver slot, which are different. To mount the module in a
transmitter slot the red side of the pin adaptor must face out. To mount the module
in a receiver slot the blue side of the pin adaptor must face out.
Refer to Optical Amplifier and Optical Switch Module Pin Adaptor (on page 128)
for pin adaptor installation instructions.
