Simulation Study of Dispersion Compensation in Optical Communication Systems Based on Optisystem

基于Optisystem仿真软件,建立带色散补偿的光纤通信系统仿真模型。仿真系统在NRZ调制格式下,利用M-Z调制器作为外调制器,使用FBG改善系统传输性能。仿真过程中,详细给出系统参数设置,通过输入输出光信号对比和眼图分析,比较不同色散补偿方式对系统性能的影响。

This paper builds the simulation model of optical communication system with dispersion cornpensation based on the optisystem. The simulation system uses M -Z as external modulator and FBG to improve transmission performance under NRZ modulation formats. When simulating, the parameter setting of this system is presented in detail. Through analyzing eye diagrams and comparing input and output signals, we obtain the influences caused by different dispersion compensation on this system.
