摘要
随着电信网络的迅速扩大和业务量的急剧增长,发展2.5Gbit/s以上速率的光缆通信系统变得日益迫切和重要。本文首先讨论了我国发展2.5Gbit/s以上速率光缆系统的必要性,然后对主要技术方案的选择、光纤的选型等进行了详细的比较和分析。最后对我国干线网下一步的发展策略提出了建设性意见。
With the expansion of telecommunication networks and growth of traffic demand, it becomes urgent and important to develop ultra-high speed optical communication systems. In this paper, the necessity of developing optical communication systems with a bit rate beyond 2.5Gbit/ s is discussed, and some detailed analysis of the selection of major technical solutions, comparison of different type of fibers and some suggestions on the strategies of national backbone networks are presented.
