Abstract
Aspects of the disclosure provide systems and methods which avoid the negative effects of Spectral Hole Burning when spectral changes are made for an optical communication system (OCS). Embodiments of the disclosure are directed to methods and systems which preform spectral holes for the range of wavelength channels expected to be used in the OCS. Embodiments include a configurable idle tone source for providing power to each of a set of idle tone wavelengths distributed across the spectral band used in the optical communication system. The configurable idle tone source is communicatively coupled to an output fiber of an optical network element and controlled such that optical power is present in the output optical fiber at each one of the set of idle tone wavelengths.
