1·The problem of low sensitivity will become seriously if DOP is used as the monitor signal of DGD in SCM system.

在光副载波复用(SCM)系统中若使用DOP作为DGD的监测信号将会遇到灵敏度低的问题。

2·The topic of this thesis is focused on the DOP technique applied to monitor the PMD of the optical link and the impact of the PMD on the PM system.

本文着重研究了偏振度法监测光纤链路PMD的性能和PMD对偏振复用系统的影响。
