| 摘 要： | 通过理论分析和数值仿真,搭建了100Gbit/s的PDM(偏振复用)-CO-OFDM(相干光正交频分复用)系统,并使用OPC(光学相位共轭)技术对100Gbit/s的PDM-CO-OFDM系统的传输性能进行了补偿。研究表明,相位共轭技术不仅能够补偿系统的各阶色散,还能补偿非线性效应,使用OPC技术能使系统的传输距离达到1 200km,在最佳补偿距离上,使用OPC的系统Q值比使用传统的DCF(色散补偿光纤)的系统Q值大6.3dB。

| Abstract: | Based on theoretical analysis and numerical simulation, 100Gbit/s polarization division multiplexing (PDM) coherent-detected optical (CO) orthogonal frequency division multiplexing (OFDM) transmission system was established. And its transmission performance was compensated by optical phase conjugation(OPC). Research results show that not only the dispersion but also the nonlinear effects in this transmission system are compensated. Using OPC technology can make the transmission distance of the system up to 1200km, and in the best compensation distance, the Q factor of the system with using OPC is 6.3dB higher than that using traditional dispersion compensating fiber(DCF). |
