摘要

针对100Gb/s偏振分复用相干光OFDM (PDM-CO-OFDM)系统中激光线宽引起的相位漂移,提出了接收机上的导频辅助相位补偿器(PC)。仿真结果表明,对于100khz线宽800km的链路,PC是非常有效的,Q的改进大于5dB。

The phase compensator for laser linewidth of 100Gb/s PDM-CO-OFDM system
We present the pilot-aided phase compensator (PC) at receiver to compensate phase drift due to laser linewidth for 100Gb/s polarization division multiplexing coherent optical OFDM (PDM-CO-OFDM) system. Simulating results are shown that PC is very effective and the improvement of Q is >5dB for 800km link with 100kHz-linewidth.
