Impact of intra-channel cross-phase modulation (IXPM) on high speed optical fiber transmission system

摘要

Analytical estimation of phase fluctuations induced by intra-channel cross-phase modulation (IXPM) in a periodically dispersion managed (DM) transmission line has been deduced using variational analysis. We have obtained several dynamical equations for various pulse parameters which are solved by Runge-Kutta method. Next the effect of various parameters such as transmission distance, input power, duty cycle and bit-rate on phase fluctuation is investigated. Finally, in some cases the analytical results are verified by numerical simulation.
