Abstract

A comprehensive simulation on the optimization of the management of the non linear effects in long haul light wave systems has been carried out by chirped RZ format as the format has significant advantages over the RZ and NRZ modulation formats in WDM systems We have tried to demonstrate that a system reach of long-haul light wave link could be significantly improved by optimizing the dispersion map in transmission path and pre-chirping input pulses. Input powers were reduced to provide quasi-linear regime. There is a need for the optimization of the length of compensation fiber on both terminal sides to maximize the effect for channel away from zero-dispersion wavelength.
