The effects of channel separation, input power and cross-phase modulation on nonlinear WDM systems with dispersion compensation

Abstract

This paper analyzes the effects of channel separation, cross-phase modulation and input power on nonlinear WDM systems with conventional single-mode fiber combined with dispersion-compensating fiber. The conclusions are: (i) The performance of different signal channels depends on the input power and the channel separation. (ii) In general, the shorter the channel separation, the shorter the maximum transmission distance; the larger the input power, the shorter the maximum transmission distance. (iii) Cross-phase modulation plays an important role on the performance of nonlinear WDM with DCF compensation.
