ABSTRACT:
A method and apparatus for reducing nonlinear phase noise that is induced in an optical transmission system by the interaction of optical amplifier noise and Kerr effect. The apparatus includes an intensity-scaled non-linear phase noise compensator. The phase noise compensator provides a phase noise compensated representation of a differential frequency by combining a measured differential frequency with a scaled differential signal strength estimate. The scale factor is derived from the number of spans in the transmission system.
