摘要： A multiplexer module and method are herein disclosed. The multiplexer module comprises a WSS configured to receive a plurality of first optical signals, selectively multiplex the first optical signals into a second optical signal, and output the second optical signal; an OPM operable to determine a power of one or more slice within a sample optical signal, the sample optical signal being selected from a group consisting of a particular optical signal of the first optical signals and a portion of the second optical signal including the particular optical signal; a processor; and a memory storing instructions that cause the processor to: validate the particular optical signal using the power of one or more slice within the sample optical signal; and if the particular optical signal is valid, cause the WSS to open a particular passband so as to multiplex the particular optical signal into the second optical signal.

摘要： A network element is disclosed herein. The network element comprises an add transceiver to generate a first optical signal having one or more optical channel; a line port optically coupled to an optical fiber link; an optical signal inspector operable to sample an optical power of one or more spectral slice of the one or more optical channel; a WSS operable to attenuate the one or more spectral slice of the first optical signal; a processor; and a memory storing instructions that cause the processor to: determine a sample power profile based on the optical power of the one or more spectral slices; generate an attenuation profile based on the sample power profile and a target power profile; and apply the attenuation profile to cause the WSS to shape the one or more spectral slices of the first optical signal into the second optical signal.

摘要： Disclosed herein are methods and systems for configuring a spectral loading pattern for a transmission line segment in an optical network, the method comprising obtaining at least one loading policy, activating at least one of the at least one loading policy, receiving a plurality of requested operations, obtaining one or more static datapoint and one or more dynamic datapoint associated with the transmission line segment, obtaining loading parameters and one or more loading algorithm from the at least one activated loading policy, generating a loading response according to the one or more loading algorithm, and changing a spectral loading pattern of the transmission line segment based on the loading response. The requested operations may identify operations to be executed in either of a current cycle or one or more subsequent cycle. The loading response may identify a subset of the operations to be executed in the current cycle.
