摘要
对分布式光纤拉曼放大器研究的历史、基本原理、优化设计以及现状和进展进行了讨论.对S波段的色散补偿型分布式光纤拉曼放大器以及采用光纤拉曼激光器作为抽运源,在前向抽运和后向抽运条件下,对5kmDCF-50kmG652光纤色散补偿型分布式光纤拉曼放大器增益光谱和噪声谱进行了研究.设计和制作了光纤光栅的增益平坦滤波器,取得了较好的增益平坦效果.FRA-1型分布式光纤拉曼放大器在校园网进行了应用试验,取得了较好的试验效果.
The history, principle, optimum design,current status and prospect of distributed fiber Raman amplifier(FRA) are discussed. The S band configuration of dispersion compensation distributed fiber Raman amplifier has been researched and developed. The gain spectrum and noise character of the 5 km DCF-50 km G652 fiber configuration dispersion compensation distributed FRA pumped by a fiber laser have been researched in the forward pump and backward pump conditions. The gain flatness filter of FRA has been designed and manufactured by the optical fiber grating and gets a good result. The application test in the campus network was done and got a good result.
