煤炭矿区光同步数字传输系列通信网

Synchronous Digital Hierarchy Communication Network for Mining Area

通过对煤炭矿区通信网应用现状的分析，以及根据国内光同步数字传输系列通信网应用情况和各公司光同步数字传输系列设备组网特点，设计了一个功能齐全且结构紧凑的光同步数字传输系列光纤通信网．结合煤炭通信专网的要求，优化光同步数字传输系列光纤通信网，建立了适合煤炭矿区通信的专网，该网不仅具有满足矿区专网的通信功能要求而且具有高速传输信息的扩展功能。

The mining area communication network and synchronous digital hierarchy(SDH) communication network at home and abroad were studied. A perfect function and structre SDH optical fiber communication network was designed. Based on the requirements of communication network in mining area, optimizating SDH optical fiber communication, a special network used mining area was built up. The network can satisfy the claims mining special and have expand function of information with high transmission.
