摘要
某电站的光传输系统是其采用的主要通信方式,在电站侧配置了接受灵敏度为-46 dBm和发送功率500 mW的拉曼放大器,以提高光纤线路的衰耗容限。从拉曼放大器的原理、特性和运用出发,讨论了拉曼放大器的替换方法和关键参考指标。
The optical transmission system is the main method of communication, in order to improve the stability of system work- ing, the station sideconfiguration of the receiving sensitivity for Raman amplifier - 46 dBm and the transmit power 500 mW, in or- der to improve the attenuation of optical fiber line tolerance. However, with the running time increases, the fault of Raman amplifier rate gradually increased, in order toimprove the efficiency of maintenance, reduce maintenance costs, this paper from the Raman amplifier principle, characteristic andapplication of the substitution method, discusses the key reference of Xiaowan power station Raman amplifier indicators, and the implementation of the Xiaowan hydropower station, has got good effect.
