Abstract
Novel tools and techniques are provided for implementing optical frequency spectral optimization in dense wavelength division multiplexing (“DWDM”) flex grid systems. In various embodiments, based on a determination that one or more gaps of optical spectrum exist in a range of optical spectrum that contains one or more media channels that support transmission of corresponding one or more first signals, a computing system may determine a network wavelength service frequency assignment for shifting frequency of at least one media channel among the one or more media channels to optimize one or more spacings among the one or more media channels in the range of optical spectrum for supporting transmission of one or more second signals; and may cause one or more optical signal devices to shift a center frequency of each of the at least one media channel, based on the determined network wavelength service frequency assignment.
