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。
The problem of low sensitivity will become seriously if DOP is used as the monitor signal of DGD in SCM system.
第三，对采用不同调制格式（包括幅移键控和二进制相移键控）的光副载波复用（OSCM）系统中，PMD引起的功率代价进行了量化。
Thirdly, we quantify the power penalty caused by the PMD in optical subcarrier multiplexing (OSCM) system with amplitude shift keying (ASK) and binary phase shift keying (BPSK).
