7.13.3 MMU Power Monitoring

Physical photodiodes P1 through P3 monitor the power for the MMU card. The returned power level
values are calibrated to the ports as shown in
been created by adding (by software computation) the relevant path insertion losses of the optical
splitters (stored in the module) to the real photodiode (P1 to P3) measurement.
