Optical frequency spectral optimization in dense wavelength division multiplexing (DWDM) flex grid systems

A system, comprising:

• one or more optical signal devices;
• and
• a computing system, comprising:
• at least one first processor;
• and
• a first non-transitory computer readable medium communicatively coupled to the at least one first processor, the first non-transitory computer readable medium having stored thereon computer software comprising a first set of instructions that, when executed by the at least one first processor, causes the computing system to:
• based on a determination that one or more gaps of optical spectrum exist in a range of optical spectrum that contains one or more first media channels that support transmission of corresponding one or more first signals, determine a network wavelength service frequency assignment for shifting frequency of at least one first media channel among the one or more first media channels to optimize one or more spacings among the one or more first media channels in the range of optical spectrum for supporting transmission of one or more second signals;
• cause the one or more optical signal devices to shift a center frequency of each of the at least one first media channel, based on the determined network wavelength service frequency assignment;
• receive, from a spectrum analyzer, one or more measurements of the one or more first media channels of the range of optical spectrum;
• and
• determine, whether the one or more gaps of optical spectrum exist in the range of optical spectrum based at least in part on the one or more measurements.
