摘要
针对强度调制/直接探测(IM/DD)系统,采用一种改进型光分路器结合数字信号处理(DSP)算法,实现了一种简单有效的偏振解复用方法。仿真结果表明,在2×40 Gb/s的偏振复用强度调制/直接探测(PDM-IM/DD)系统中,该方法能够较好地分离两路偏振复用信号,并且算法收敛迅速,与传统IM/DD系统相比,误码率为10-4时对应的功率灵敏度仅为-2.3 dBm。
Abstract
A simple and effective polarization demultiplexing method employing improved optical splitter and digital signal processing (DSP) algorithm for intensity-modulation direct-detection (IM/DD) optical communication systems is proposed. Simulation results show that in a 2×40 Gb/s polarization-division-multiplexing intensity-modulation direct-detection (PDM-IM/DD) optical transmission system, the PDM signals can be effectively separated. The DSP algorithm can rapidly converge with the receiver sensitivity of -2.3 dBm at bit error rate of 10-4.
