Transmission Network In Hebei Province And Practice Of Design Optimization

Transmission network is a network-based telecommunications network, transmission network as a platform for integrated telecommunications services bearing its impact on network planning is China Unicom Hebei market competition in the future a key factor in the success or failure. New China Unicom, the former telecommunications company operating a single business moves in the direction of the whole business, which will require that the competitive telecom environment towards standardization, quality of service, the business personal direction. Transmission network carrying broadband services as the basic network, the existing supply of fiber optic transmission network bandwidth, network reliability, network quality of service, business adaptability, and new business has been increasingly unable to meet rapidly growing demand. The face of severe competitive pressures, construction for the broadband, efficient, highly adaptable business network of provincial trunk is imminent. Capacity of the provincial network two planes nearly saturated, can not meet the business needs, so in the current and future competitive market environment, the full use of existing transmission network resources, build a new generation of high-capacity transmission network in the province the third plane, to meet the community and a variety of business needs for bandwidth has become a priority.In the second chapter of this technology, SDH and WDM transport networks are introduced, the Ⅲ and Ⅳ of the demand for the Hebei Province, and network communication services, based on the analysis of the status quo, concluded:Hebei transmission network must be optimized, the optimization scheme is to build a new network three-plane system. Chapter V describes in detail the level provincial network triplane DWDM, SDH level and system configuration design.
