Abstract
A method includes calculating a phase of a light pulse that is propagating along an optical fiber of a fiber broadband communications network, calculating a change in the phase of the light pulse due to a nonlinearity, determining a cause of a portion of the change in the phase, wherein the cause is at least one of: a self-phase modulation, a cross-phase modulation, or a four-wave mixing, and initiating at least one action to mitigate the nonlinearity, wherein the at least one action is selected based on the cause that is determined.
