摘要
为了优化光纤通信系统色散补偿方案,采用软件仿真的方法设计了一个用色散补偿光纤进行色散补偿的单信道通信系统,利用光纤环形镜的全反射特性使该系统的色散补偿方案得到了优化,补偿效果良好,并节约了成本。对色散补偿及光纤环形镜的工作原理进行了理论分析和仿真验证,取得了系统在2.5Gbit/s和10Gbit/s下Q参量和眼图的仿真数据,分别找出了两个信号速率下的系统最佳输入功率。结果表明,系统在2.5Gbit/s下的最佳输入功率为13dBm,此时Q参量达到了172.88;系统在10Gbit/s下的最佳输入功率为6dBm,其相应Q参量为45.96。这一结果对实际应用中光纤通信系统的色散补偿是有帮助的。
In order to compensate dispersion in an optical communication system, a single channel dispersion compensation system which used of dispersion compensating fiber was designed and simulated. The system was optimized by a fiber loop mirror so that it economized the cost, and the effect of dispersion compensation was fine. The simulation results such as Q factor and eye diagram were given and analyzed in this system with different velocity of 2.5Gbit/s and 10Gbit/s, and their input power were obtained. When the system＇ s velocity is 2.5Gbit/s, the optimum input power is 13dBm, and Q factor is 172.88; When the system＇ s velocity is 10Gbit/s, the input power is 6dBm and the corresponding Q factor is 45.96. The obtained results are helpful for the application of dispersion compensation in an optical communication system.
