摘要

本文通过数值模拟研究了在线色散补偿对100Gb/s极化分复用相干光OFDM (PDM-CO-OFDM)系统的影响。结果表明，附加掺铒光纤放大器(EDFA)中的自发发射噪声(ASE)放大和色散补偿光纤(DCF)中的非线性对在线色散补偿CO-OFDM系统的性能有很大影响。为了平衡以上两种影响，对DCF的输入功率进行了优化。小于标准单模光纤(SSMF)的DCF最佳输入功率为5dbm。此外，剩余欠补偿色散对CO-OFDM有利，当剩余色散从0增加到700 ps/nm时，最大Q值下降从3.2 dB到1.2 dB。

Inline dispersion compensation effect for 100GB/S PDM-CO-OFDM long-haul transmission systems

In this paper influence of inline dispersion compensation in 100Gb/s polarization division multiplexing coherent optical OFDM (PDM-CO-OFDM) system is studied by numerical simulation. The results show that amplified spontaneous emission noise (ASE) in additional Erbium-doped fiber amplifier (EDFA) and dispersion compensation fiber (DCF) nonlinearity has great impacts on the performance of inline dispersion compensation CO-OFDM system. In order to balancing both above effects, the input power of DCF is optimized. The optimal input power into DCF less than standard single mode fiber (SSMF) is 5 dBm. Furthermore, residual undercompensated dispersion per span is beneficial to CO-OFDM, the drop in maximum Q varies from 3.2 dB to 1.2 dB as the residual dispersion increases from 0 to 700 ps/nm compared with no inline compensation.
