摘要
介绍色散补偿光纤DCF及动态啁啾光纤光栅FBG的补偿技术并比较其优缺点,提出在传统光传输系统末端加入动态FBG的方案,通过Optisystem仿真软件搭建40Gbit/s的光传输系统,用FBG仿真光传输400km的Q值为3.745,误码率为7.419 42e-5,用DCF静态混合补偿和静态与动态相结合的补偿方案分别仿真并比较两种方案传输相同距离的Q值和误码率的大小,证明提出的静态加动态的方案提高了光传输性能。
We introduced the dispersion compensation principles of dispensation compensation fiber(DCF)and fiber Brag grating(FBG),compared their advantages and disadvantages,proposed adding the FBG into the end in traditional optical fiber transmission systems.We designed a transmission system with a capacity of 40Gbit/s by using Optisystem software and studied three dispersion compensation schemes.If the FBG dispersion compensation was used only,its Qvalue was 3.745 and its bit error ratio(BER)was 7.41942e-5with the optical signal transmission of 400 km.The scheme of DCF static mixed compensation and the combination scheme of static and dynamic dispersion compensation were simulated,and the Qvalue and BER of the two schemes for transmission of the same distance were compared.It is proved that the scheme combined the static with the dynamic compensation can improve the optical transmission performance.
