摘　　要：分析了光网络节点串扰产生的原因以及级联光交叉连接 ( OXC)和光分插复用 ( OADM)系统的串扰 ,对级联系统进行模拟 ,计算并分析了光开关隔离度、上路信号的功率差对系统误码率的影响 ,得出了光开关隔离度是产生串扰的主要原因。This paper analyzes why the crosstalk is produced in optical node,and also analyzes the crosstalk of cascade system of OXC and OADM.The influence of both optical switch's insulation and the input signals power difference on system BER were calculated and analyzed.We also simulate it in cascade system of OXC and OADM,and draw the conclusion that non-ideal character of optical switch's insulation is the main reason for producing crosstalk and equalizing the optical power before the optical switch has better effects,etc.

关 键 词：级联光交叉连接 光分插复用 串扰 光纤通信 光网络 误码率
