Electrical power, changing with differential group delay (DGD) and detected from an optical communication link, can be used as feedback signals of compensating for PMD.

光纤通信线路检测到的电功率随差分群延迟变化，可以作为PMD补偿的反馈控制信号。

Moreover, one would expect reductions in job security to require a compensating differential even to maintain the current level of supply.
