Abstract

In this paper cross-phase modulation (XPM) and its impact on multispan NRZ-modulated wavelength division multiplexing (WDM) systems is examined. An analytical model is presented to assess the signal degradation. The impairments due to XPM are related to a Q-factor. The presented formulas are examined for different dispersion compensation schemes and also mixed-fiber systems. The analytical models are verified by system simulations employing the split-step Fourier method. To determine the impairments due to XPM the pump-probe model is used, which assesses the distortion of an unmodulated probe channel. It is shown that this model is applicable to NRZ systems. Existing analytical models are extended for certain conditions, e.g. given dispersion compensation schemes such as the distributed under-compensation scheme (DUCS) or the full-inline and optimized post compensation scheme (FOCS). Furthermore, a formula will be suggested to estimate the degradation of performance, if further WDM channels are added to an existing system.
