淮北煤矿专用通讯网光缆SDH传输网规划建设

淮北煤矿光缆SDH传输网是未来矿区宽带通信业务、数据、图、有线电视、INTERNET等的主要承载。目前，网络规划和设计工作业已完成，工程建设正在顺利进行，2002年底即可全部建成。工程实施建设的是通信、计算机、有线电视三网合一的传输网络，光缆芯数合建将减少重复投资，节省大量资金。网络建成后对增强专用网参与市场竞争的实力、拓宽业务渠道、更好地服务于矿区及今后淮北煤矿通信事业的发展都将起到非常重要的作用。

The Programming Developments of the Special Communication Network and the SDH Transmission Network of Fiber Optic Cable in Huaibei Coal Mine

The Fiber Optical Cable SDH Transmission Network of the Huaibei Coal Mine is the main loader of broad-communication service, data, image, cabled television, and Internet of the coal mine in the future. Now the work of the network programming and designing have already been completed. The engineering into practice developments is the communication network which links three nets of the communication, computer, and cabled television as one. Through core numbers of fiber optic cable matched to set up, it will reduce the repeated investment and save large quantity of money. After the network is built up, it will has an very important effect on increasing the capacity of special communication net participating in market competition, and widening the business ditch, better serving for the coal mine, and developing the communication undertaking of the Huaibei Coal Mine.
