Abstract
A method, a controller, and an optical section include performing an analysis to determine an amount of power offset on any in-service channels in an optical section due to a capacity change with a channel; defining a step size to ensure the capacity change does not exceed an offset limit based on the analysis; performing the capacity change in one or more iterations using the step size to limit the capacity change; and performing an optimization between each of the one or more iterations to adjust amplifier gains in the optical section to compensate for offsets on the in-service channels caused by a previous iteration.
