摘　　要：本文分析了波分复用 (WDM)全光通信环网中串扰起因 ,指出 WDM环网中的串扰分析可以简化为单一串扰源的情况。从接收机检测光电流的概率分布函数出发 ,给出了单一串扰源的精确误码率表达式 ,串扰功率代价的分析结果与论证实验的测量非常吻合。This paper studies the intraband cro ss talk mechanisms in wavelength division multiplexed (WDM) ring networks.In WDM ri ng networks,the crosstalk analysis can be simplified to the single crosstalk sou rce case.The exact BER expressions of single crosstalk path are derived from the probability density function of the output current in the optical receiver.The calculated crosstalk penalties are in good agreement with the experimental data.
