摘　　要：用琼斯矩阵本征分析法和邦加球法 ,分别测量了 2 2km和 75kmG .6 5 2单模光纤中的二阶偏振模色散 ,并对其平行分量、垂直分量、PCD(Polarizationdependentchromaticdispersion)、消偏振项、各个分量的统计特性及其影响进行了详细的分析 ,得到了二阶偏振模色散随波长的分布情况及统计特性 从统计结果可以得到 ,与PCD项相比 ,消偏振项在二阶偏振模色散中起主要作用The second-order Polarization Mode Dispersion of 22 km and 75 km single mode fiber were measured with Jones matrix eigenanalysis method and Poincare Sphere Method. The parallel component, perpendicular component, depolarization effect, PCD, the statistical characteristics and effects of these components were analyzed. The result is that the perpendicular component had a greater impact on pulse than that of the parallel component in mean. This will be a very helpful researching work for second-order PMD compensation.
