摘要
拓展光纤的可用光学带宽是应对不断增加的光传输系统容量需求的有效手段。将传统C波段光放大器的工作频谱展宽到超级C波段的方案传输性能可控,管理简单;在C波段光放大器上增加并联的L波段光放大器方案,增加管理复杂度,牺牲部分传输性能,但对传输容量提升大;在将L波段放大器工作频谱进一步向长波长延伸的探索中,如何实现高泵浦转换效率和平坦增益的折衷仍是待解决的技术难点。
Extending more usable optical bandwidth is an effective solution for dealing with the transmission capacity demand multiplication.It is with acceptable performance and easy for management by extending conventional CBand to super CBand.Adding Lband amplifier in parallel with CBand amplifier will bring some performance penalty,while almost double the bandwidth.The technical solution for further extending to super Lband is still under investigation,to study how to achieve high pump conversion efficiency as well as gain flatness.
