摘要
相对于传统长距离光纤传输系统中的中继器,光放大器是新一代光纤通信系统中必不可少的关键器件,是光纤通信发展史上的一个重要里程碑。文章分别介绍了目前长距离光传输网中应用的各类光放大器,通过案例详细讨论了带掺铒(EDFA)的喇曼光纤放大技术在实际线路中的应用,能有效改善线路光信噪比(OSNR),适用于G. 652、G. 655等光纤,能很好的提升系统传输性能。
Relative to the repeater used in the traditional long distance optic fiber transmission system, fiber amplifier is the essential key device in the new generation fiber optic communication system. It is an important milestone on the development history of optic fiber communication. The paper introduced and discussed current application of various optic amplifiers in long distance optic transmission net, and also, through cases, discussed the applications of EDFA optic fiber amplifiers plus Ramam optic fiber amplifiers in practice. This can improve OSNR effectively, suitable for different optic fibers, such as G.652, G.655 etc., and promote systematic transmission performance very well.
