摘要
考察了后向抽运分布光纤拉曼放大器(B-DFRA)对光通信系统传输性能的改善.分别讨论了B-DFRA的两种可能用途:1) 作为第一级预放器与掺铒光纤放大器(EDFA)及光接收机一同构成接收终端.2) 在一个有中继的长距离光通信系统中作为各级EDFA的预放器.针对这两种用途分别计算出B-DFRA对系统性能的影响,并给出选择抽运功率的原则.
Abstract
An optical communication system with both EDFA and B DFRA is introduced. Two applications of B DFRA are studied. The first case is a receiver terminal with a receiver, an EDFA preamplifier and a B DFRA. The second case is a multistage point to point optical repeated system with both EDFA and B DFRA. The performance improvements in the two cases are calculated. The principle of the Raman pump power selection is discussed.
