光纤通信系统中色散补偿的研究

Study on Dispersion Compensation in Fiber Communication System

本文从光纤色散和啁啾光栅所提供的延时两方面对光通信系统中的色散补偿进行了分析，表明每隔放大器的中继距离插入一啁啾光栅进行色散补偿可实现信号无失真传输，在此基础上提出了在中继器中同时实现全光信号放大和色散补偿的光纤通信系统方案。

This paper analyses dispersion compensation in fiber communication system from fiber dispersion and dispersion accounts provided by chirped grating.It is proved that inserting a fiber grating at a distance between two amplifiers may transmitting signals without distortion.Giving a method of fiber communication system completing simultaneously all optical signal amplification and dispersion compensation in repeater.
