长途干线波分复用的技术分析

Technology Analysis of WDM in Toll Trunk

随着波分复用设备的商用化速度加快及多媒体等各种信息对传输带宽的要求急剧增加 ,中国电信利用波分复用技术对八横八纵光缆中的一部分进行了扩容 ,广泛采用 8× 2 5Gbit s密集波分复用 (DWDM)系统 ,并选用了 4× 10Gbit sDWDM系统进行试验。文中对这两种DWDM系统作一个初步的技术分析。

Accompanied with the commercialization of DWDM technologies and the increased need for transmission capacities for all kinds of information, China Telecom adopted DWDM equipment for some backbobne systems of national transport network Lucent Technologies provides 8×2 5 Gbit/s DWDM system for most of projects, while Nortel Networks provides 4×10 Gbit/s DWDM system for only a trial This article introduces technology of DWDM with these two samples
