摘　　要：在多个信道和任意调制的情况下 ,推导 XPM效应对光纤波分复用 (WDM)系统性能的影响 .通过数值模拟计算表明 ,在此情况下的 XPM效应是限制系统性能一个重要因素 ,应在系统功率预算中给予考虑 .同时 ,提出抑制 XPM影响的几种方法 .Under the condition of multiple channel and arbitrary modulation, the authors derive the influence of crossc phase modulation (XPM) effect on the syslem performance of wave division multiplex (WDM). As indicated by numerical analog computation, XPM effect is an important factor restricting system performance which should be taken into account in the budget of system power. Several methods are proposed for inhibiting the influence of XPM.
