Reconfiguring Forward Signal Routing
109
2x4 Redundant Forward Configuration Modules
Two primary receivers (RCVR 1 and RCVR 3) and two redundant receivers (RCVR 2
and RCVR 4) each pair feed 2/3 output ports.
The first pair of primary (RCVR 1) and redundant (RCVR 2) receivers feeds the right
side of the amplifier (Ports 4 and 5/6). The second pair of primary (RCVR 3) and
redundant (RCVR 4) receivers feeds the left side of the amplifier (Ports 1 and 2/3).
The Status Monitor/Local Control Module switches between primary and
redundant receivers upon loss of optical input to a primary receiver, and switches
back to the paired primary when optical input is restored.
Install the first set of receivers as follows:
 first primary receiver RCVR 1
 first redundant receiver RCVR 2
Install the second set of receivers as follows:
 second primary receiver RCVR 3
 second redundant receiver RCVR 4
4-way forward segmentable node
The following diagram illustrates forward path signal flow in this module.
