Chapter 5 Multiplexer and Demultiplexer Cards
and input ports is monitored through the use of virtual photodiodes. A virtual photodiode is implemented
in the firmware of the plug-in module. This firmware calculates the power on a port, summing the
measured values from all single channel ports (and applying the proper path insertion loss) and then
providing the TCC2/TCC2P card with the obtained value.

5.5.2 Power Monitoring
Physical photodiodes P1 through P8 and virtual photodiodes V1 and V2 monitor the power for the
4MD-xx.x card. The returned power level values are calibrated to the ports as shown in
