Abstract
Systems and methods to control optical signals in a spectrally overlapped, flexible grid spectrum system include receiving measured power within a control bandwidth for an optical signal, wherein the control bandwidth is less than a spectral occupancy of the optical signal and equal to or greater than a resolution bandwidth of a measurement device configured to measure the measured power; and controlling the optical signal based on the measured power and a target power within the control bandwidth. The optical signals can include Nyquist spaced or super Nyquist spaced signals in a media-channel.
