Aspects of the disclosure provided systems and methods which mitigate negative effects of Spectral Hole Burning when spectral changes are made. 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 optical communication system. In some embodiments this is achieved by controlling the network to ensure optical power is provided at each of a set of idle tone wavelengths distributed across the spectral band used in the optical communication system. In some embodiments a routing and spectrum assignment function satisfies new service requests while maintaining power to the set of idle tone wavelength functions. In some embodiments a network control function configures Reconfigurable Optical Add/Drop Multiplexers to broadcast idle tone wavelengths to provide power to each idle tone in each section.
