摘　　要：首先阐述了扰偏器的工作原理,对实验中所用的扰偏器的工作特性做了测试,给出了测量结果;搭建了4×10Gb/s光时分复用信号产生系统,将扰偏器加在系统中,测试了扰偏器工作前后系统的性能。实验结果表明,扰偏器明显消除了偏振效应给系统性能带来的不良影响。Principle of the polarization scrambler is introduced in this paper. And the performance of the polarization scrambler is tested. In the experiment, a 4×10Gb/s optical time division multiplexing （OTDM） signal generating system is established and the polarization scrambler is employed in the system. Then, the performance of the system with and without polarization scrambler is mea- sured. The experimental result shows that, the quality of the signal is improved when the polarization scrambler is working.
