Patent abstract
A device for increasing a number of optical signal channels detectable by an optical channel performance monitor having M detectors includes an input to receive an optical signal, a filter assembly coupled to the input, a controller connected to the filter assembly, and an output. The controller selectively configures the filter assembly to filter the optical signal in a repeating sequence of periodic passbands. The output transfers an output of the filter assembly to an optical channel performance monitor.
