摘　　要：光纤的偏振模色散是限制光纤长距离传输的一个主要因素。在相同条件下,通过实验分析了搓动与未搓动光纤的PMD值,表明了搓动光纤的PMD值小于未搓动光纤的PMD值,且PMD链路值波动更稳定。A mostly factor to restricting the long-distance transmission of fiber is PMD. By testing the PMD between twisted fiber and without twisted fiber in same condition ,indicating that PMD of twisted fiber is smaller, also it＇ s rolling is more stable.
