摘要

为实现光信号的有效传输

研究了DCF（色散补偿光纤）和FBG（光纤布拉格光栅）的基本原理

利用Optisystem软件对基于RZ（归零）码调制格式的单信道传输系统中的两种色散补偿方法进行仿真

分别比较了前置补偿和后置补偿的色散补偿性能

并在此基础上提出了FBG中间色散补偿。仿真结果表明

采用FBG中间色散补偿后系统的Q值均高于另外两种色散补偿方式。进一步采用中间补偿的级联FBG模块作为波分复用系统的色散补偿器件

利用Optisystem软件对此补偿方法进行仿真

结果表明

该方法在长距离传输时仍能保持良好的补偿效果。

Abstract

In order to achieve effective transmission of optical signals

the basic principle of different dispersion compensation methods（dispersion compensation fiber and fiber Brag grating）is studied.A single-channel transmission system based on RZ modulation format by Optisystem is designed and two dispersion compensation schemes（pre-compensation

post-compensation）of DCF and FBG is studied.In this paper

the intermediate dispersion compensation method based on FBG is proposed.Simulation results show that the Qvalue of the system is higher than the other two methods when use the FBG intermediate dispersion compensation.The intermediate cascaded FBG module is further proposed as a dispersion compensation device of WDM system.The simulation model in Optisystem is established.Simulation results show that this method can maintain good compensation effect even if the transmission distance is long.
