摘要
文章阐述了光纤拉曼放大器(FRA)在延长系统传输距离,提高单信道比特率,减少信道间距,扩展传输频谱,S波段放大及提供高增益方面的巨大作用,同时介绍了FRA的最新成果.
This paper gives a general and detailed introduce to the recent progress of fiber Raman amplifier(FRA) in extending transmission length, increasing bit rates, reducing channel space and exploiting new transmission spectrum. Then the lumped Raman amplifier providing high gain in the Sband and broadband spectrum is introduced.
