摘要
本文针对高速率光传输系统中的色度色散问题,利用啁啾光纤光栅,设计了后置补偿、前置补偿和混合补偿三种方案并实现了320km的G.652光纤单信道40Gbit/s的无中继传输,仿真实验结果表明较之后置补偿和前置补偿,混合补偿具有最好的色散补偿性能。
Aiming at the chromatic dispersion problem in high- speed optical transmission system and taking advantage of chirped fiber Bragg gratings in this paper, we designed three schemes： post - compensation, pre - compensation and symmetrical compensation. The simulation realizes the unrepeatered transmission of G. 652 fiber single channel with 320km long at the speed of 40Gbit/s and the results of simulation experiment show that symmetrical compensation, compared with post - compensation and pre - compensation, is optimal for compensating dispersion.
