Abstract

Based on 40Gbit/s Return-to-zero differential phase-shift keying (RZ-DPSK) DWDM system, the four dispersion management programs are proposed to suppress optical pulse phase jitter induced by kerr nonlinear effect including the self-phase modulation (SPM) and cross- phase modulation (XPM). The tolerance against the kerr nonlinear effect is studied through detailed numerical simulation by Split-Step Fourier Method. The results are showed that there are more than 2dB power penalty difference for different channels in a program and 5dB power penalty difference for different compensation programs. Through appropriate selection, DPSK system must be having 2dB performance improvement.
