Partial activation of a media channel on channel holder-based optical links

Abstract:

Systems and methods include, responsive to provisioning a media channel (52) on a degree, wherein the media channel (52) is a contiguous portion of optical spectrum supporting N channels, N is greater than 1, causing allocation of optical filter bandwidth in an optical multiplexing/demultiplexing device for M channels (56) in the media channel (50), where M is less than N; causing provisioning of the M channels (56) in the media channel (50); and causing configuration of channel holders in the media channel from a channel holder source (20) for a part of the portion of the optical spectrum unoccupied by the M channels (56).
