We experimentally demonstrate a polarization-mode dispersion (PMD) monitoring technique that is insensitive to chromatic dispersion (CD) utilizing a polarizer and a low-speed detector for an 80-Gb/s polarization-multiplexed return-to-zero differential phase-shift-keying (pol-muxed RZ-DPSK) data channel. Measured RF power increment of 16.2 dB, which is insensitive to 0 approximately 100 ps/nm CD, is measured in the presence of the increasing differential group delay (DGD) from 0 to 12 ps. High-speed components are not required for monitoring the PMD on the pol-muxed data channel, which means that the proposed technique is potentially applicable to the higher speed pol-muxed data channels.
我们通过实验演示了一种偏振模色散（PMD）监测技术，该技术利用偏振器和低速探测器，对80Gb/s偏振复用归零差分相移键控（偏振复用RZ-DPSK）数据通道的色散（CD）不敏感。在差分群延迟（DGD）从0增加到12ps的情况下，测量到16.2dB的射频功率增量，该增量对0至100ps/nm的CD不敏感。监测偏振复用数据通道上的PMD不需要高速组件，这意味着所提出的技术可能适用于更高速度的偏振复用数据通道。
