摘要
首先介绍了光纤分布式拉曼放大器的工作原理、增益带宽和噪声特性 ,接着阐述了它与 EDFA组合使用对系统性能的影响 ,然后指出传输系统设计应考虑的几个问题 。
The schematic, gain bandwidth performance and noise figure of distributed Raman amplifier are introduced first. Impact of Raman+EDFA hybrid amplifier on system performance are described then. Several problems on optical transmission system design are indicated. Raman amplifier application is presented at last.
