混合型色散补偿光纤喇曼放大器由普通G6 5 2光纤和色散补偿光纤 (DCF)组成 ,包括 :DCF +G6 5 2、G6 5 2 +DCF和G6 5 2 +DCF +G6 5 2。讨论了它们的工作原理 使用FRA OptiAmplifier4 .0软件对其进行了优化设计 ,最佳结构为G6 5 2 +DCF 它可补偿光纤网络的色散 ,扩展通信波长范围 14 2 7nm的喇曼激光器作为激发源 ,用Q8384光谱分析仪测量了光纤的喇曼增益谱和小信号放大光谱 ,混合型色散补偿光纤喇曼放大器在S带和C带具有 88nm的增益带宽 ,这增加了光纤通信网络的传输通道
Hybrid Dispersion Compensating Fiber Raman amplifiers consist of normal G6 5 2 fibers and dispersion compensating fibers (DCF), including: DCF + G6 5 2, G6 5 2 + DCF and G6 5 2 + DCF + G6 5 2. Discussed their working principle Optimized design with FRA OptiAmplifier4.0 software, the best structure is G6 5 2 + DCF It can compensate the dispersion of optical fiber network and extend the communication wavelength range 14 2 7nm Raman laser as the excitation source , The Raman gain spectrum and the small signal amplification spectrum of the fiber were measured with a Q8384 spectrometer. The hybrid dispersion compensation fiber Raman amplifier has a gain bandwidth of 88 nm in the S and C bands, which increases the transmission path of the optical fiber communication network
