Abstract

This work investigates the effect of phase fluctuation averaging on phase fluctuation induced by intrachannel four-wave mixing (IFWM) in highly dispersed differential phase-shift keying transmission systems. Through repeatedly averaging the phase fluctuations of adjacent pulses, a simple analytical model and numerical simulation revealed that the IFWM-induced differential phase fluctuation is suppressed and convergent, even after an ultralong transmission. The influence of averaging the phase fluctuations on the bit error rate is also evaluated by the semianalytical method.
