摘　　要：推导了多个信道和任意调制的情况下 XPM效应对光纤 WDM系统性能的影响 ,通过数值模拟计算表明了在此情况下 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。提出了抑制This paper investigates the influence of cross phase modulation (XPM) on the perfor mance of the multi channel multiplexed systems. By digital simulated calculating, the XPM induced system optical power penalty is proved to be large enough to be considered in system design and maybe one of the most important nonlinear effect. Several methods of avoiding effect on XPM are introduced.
