摘　　要：光纤的偏振模色散(PMD)是光纤高速率和长距离传输的重要制约因素之一.对三盘24芯光缆的每芯光纤及其串接构成模拟长途链路的PMD值进行实际测量,并用统计平均的方法进行估算,得出了链路PMD的实测值与估算值非常接近的结论,这对光缆链路的设计具有指导作用.The polarization mode dispersion（PMD） of optical fibers is one of the important factors that constrain high rates and long distance communication.Based on real test of PMD of each fiber and linked chains for three reels of 24 fibers cable,and calculating their statistic average value for each chain,a conclusion is obtained that PMD＇s statistic average value is very close to real test value for each chain.It is a very useful conclusion for optical chain design.
