Abstract
In wavelength division multiplexing (WDM) optical transmission system, crosstalk due to cross-phase modulation (XPM) is one of the most significant nonlinear effect. On the other hand in a first order group velocity dispersion (GVD) compensated system, second order GVD also restricts bit rate. This paper presents an analytical treatment of XPM effect in presence of second order GVD in WDM fiber-optic transmission system. It is found that in long haul high bit rate system, second order GVD plays a critical role in limiting performance in a WDM system. Results show that XPM crosstalk penalty in presence of second order GVD is 43 dB more for dispersion shifted fiber than standard single mode fiber at 10 GHz modulation frequency and 0.8 nm channel spacing.
