ABSTRACT:
A system and method for spectral loading unutilized channels of a partially loaded WDM system may be used to suppress spectral hole burning (SHB). Dummy tones may be loaded at different loading wavelengths within the band of system wavelengths such that the loading wavelengths are associated with a subset of unutilized channels in the WDM system. The loading wavelengths may be selected and spaced based on a distortion in the gain spectrum of the partially loaded WDM system such that the dummy tones alter the distortion to provide a desired gain spectrum.
