Abstract
Systems and methods for monitoring non-linear effects along an optical communication line transmitting an optical signal, the optical signal being formed from a plurality of sub-signals, each sub-signal being carried over a corresponding wavelength of a plurality of wavelengths. The method includes modulating, by a power dither, an optical power of a first set of sub-signals among the plurality of sub-signals at an output of a first amplifier assembly of the optical communication line; and determining, at a second amplifier assembly of the optical communication line downstream from the first amplifier assembly, a gain modulation affecting a second set of sub-signals due to the modulation of the optical power of the first set of sub-signals.
