Paper Abstract

An extensive investigation has been carried out, by computer simulation, to evaluate the impact of self phase modulation (SPM) on residual dispersion for a wavelength-division multiplexed (WDM) system at a bit rate of 10 Gbit/s. Degradation of the eye opening of the transmitted pulses at the output of the transmission fiber due to interplay of the SPM and the group-velocity dispersion effects is investigated for post- and bi-end compensation configurations, including residual dispersion. Hence the eye-opening penalty and the threshold power limit at 3-dB eye-opening penalty are determined for both the configurations. It is found that the bi-end compensation configuration offers the best performance in respect of the SPM effect and that for a WDM system positive residual dispersion should be used.
