G.655光纤偏振模色散测试方法对比及光纤链路测试探讨

G．655 Optical Fiber Polariscope Mode Dispersion Testing Methods Comparison and Discussion on Optical Fiber Link Test

介绍G．655光纤的偏振模色散（PMD）测试方法；通过对比测试、光缆敷设前后PDM值变化测试分析，以及光缆串接测试与计算值比较，摸索G．655光纤的PMD的变化。

It firstly introduces G．655 optical fiber PMD testing methods and then gropes optical fiber PMD change by the aid of comparative tests the analysis of PMD value change before and after the laying out of optical cable optical cable concatenation test．
