基于啁啾光纤光栅色散补偿问题的思考

色散已成为光纤长距离、高速率通信中的巨大障碍.鉴于色散补偿光纤插入损耗大、易引入非线性效应等缺点,文章采用啁啾光纤光栅对系统进行色散补偿,克服了以上不足.通过分析啁啾光纤光栅色散补偿的原理,结合理论分析,提出在多通道波分复用系统中使用啁啾光纤光栅,以实现长距离无中继传输.

Study on chromatic dispersion compensation with chirped fiber gratings

Chromatic dispersion has become an enormous obstacle to the development of long-haul high-speed fiber-optic communications.So Dispersion Compensation Fibers(DCF) are usually used to solve this problem,but they are liable to great insertion loss and nonlinear effects.On the basis of analyzing the dispersion compensation principle of the chirped fiber grating,we propose to use it in multi-channel WDM systems so as to realize long-haul repeaterless transmissions,while overcoming the above-mentioned shortcoming...
