摘 要
由于网络迅速发展迫切需要快速增加传输带宽， SDH传输网可以较好的解决这个问题。SDH传输网相对于传统PDH网络存在无法比拟的优势，不仅可以应用在传统的电信领域，还可以使电信网络结构演变成为统一网络。通过对SDH技术理论的分析研究，讨论了SDH传输网组网中需要重点考虑的问题。并设计传输速率为2.5G的本地SDH传输网。拓扑结构选择环形，自愈保护方式选择二纤双向复用，设备选择华为设备OptiX 为网络站点的主要设备。

Abstract
As the network is an urgent need for the rapid development of the rapid increase in transmission bandwidth, SDH transmission network can be used to solve this problem. SDH transmission network to the traditional PDH network are incomparable advantages, Not only can be applied in the traditional telecommunications field, but also can enable the telecommunications network architecture evolved into a unified network. Based on SDH technology theory analysis, discussion of SDH Network needs to focus on the issue. And the design speed of 2.5 G local SDH transmission network. Ring topology choice, self-healing methods of two-way choice of two fiber multiplexing, Equipment Selection Huawei equipment OptiX for the main site network equipment.
