Abstract
Cross Phase Modulation is one of the major interchannel nonlinearity which occurs in multichannel systems. It is a nonlinear effect where the intensity of the optical signal propagating through the fiber alters the refractive index of the transmission medium through the Kerr effect. This causes phase shift between the co propagating signals and polarisation rotations even in the absence of polarisation mode dispersion. We theoretically and experimentally analyse the effects of XPM using OPTSIM simulator. A method to reimburse the effects of XPM is also proposed
