Abstract

A performance analysis method of WDM optical fiber transmission system is proposed in this paper based on a semi-analytic approach. Here signal distortion caused by combined effects of fiber chromatic dispersion, SPM and XPM is obtained from computer simulation, while ASE noise and crosstalk due to fiber FWM are treated as additive Gaussian noise in the optical domain. An analytic formula for FWM noise power in a dispersion-managed system is also proposed. As an example, non-zero positive dispersion fiber and large negative dispersion fiber is used as transmission and dispersion compensating fiber respectively in a wide-real WDM network. Our results of performance analysis show that appropriate design of dispersion management scheme for the WDM network may achieve 4 X 10 Gb/s transmission over 2000 km with 6 dB power margin.
