  • Patent number: 12126376
    Abstract: In an alien wave system, one or more transponders connected to a line system may be owned and operated by a different entity from the entity that owns and operates the line system. In such a situation, diagnosing and correcting faults, and achieving good performance, may be challenging. As such, a system and methods for interoperability in an alien wave system are provided.

  • Publication number: 20240235677
    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.
