Abstract
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.
