双向网设计中反向回路扩容方法探析

Discussion on the Design of Bidirectional Network Reverse Loop Expansion Method

网络的建设速度似乎永远跟不上网络新业务的发展速度,刚建的网络,如果业务发展迅猛,很快便遇到瓶颈。针对目前网络发展中反向回路的扩容问题,提出拆分光节点、调整网络结构、使频率搬移或堆积以及提高调制频谱利用率等几种扩容方法,并对每一种方法进行简要的解析和探讨。

Network construction speed seems not network new business development rate, just build the net- work, if the business is developing rapidly, soon encountered bottleneck. This article in view of the present network development of reverse loop expansion problem, proposed splitting optical node, adjust the structure of the network, so that the frequency shift or accumulation and improve the modulation spectrum utilization of several expansion methods, and each method has carried on the brief analysis and discussion, for your refer- ence.
