Abstract:
1. An optical power control system configured for use with a wavelength division demultiplexer, said optical power control system comprising: a plurality of photodetectors connected so as to monitor output power on a plurality of outputs of said demultiplexer, each of said outputs carrying a different WDM channel; and a control system that receives power level indications from said plurality of photodetectors, controls a gain of an optical amplification system providing input to an optical filter, and controls a tilt of said optical filter providing input to said demultiplexer; and wherein said control system sets a gain of said optical amplification system such that a power level indication based on said output powers monitored by said plurality of photodetectors is set within a desired range and sets a tilt of said optical filter such that a difference in said monitored output powers is reduced.
