Dependence of self-phase modulation impairments on input pulse shape over a dispersion-compensated transmission link using standard single-mode fiber

The effects of pulse shape on self-phase modulation on 10-Gb/s pulse transmission over dispersion compensated fiber links using dispersion compensating fiber technique are investigated numerically. The transmission performance of a dispersion compensated fiber link using standard single-mode fiber is evaluated when the input pulse varies from a Gaussian to a super-Gaussian pulse with very sleeper leading and trailing edges. The interaction between SPM and GVD are stronger for a pulse with steeper leading and trailing edges.
