Shijiazhuang Unicom Transmission Network WDM Technology Application Research

With the rapid development of the telecommunications industry, supplied by the operators of the main business in the rate and business also is in rapid expansion, a variety of new business continued to occur, as the basis of the transmission network have become increasingly large and complex nature. The operator of the transmission network after years of construction, network infrastructure is perfect with each passing day, clear in hierarchy. But as the transmission circuit demand grow steadily, transmission construction frequency accelerate and transmission network expansion, transmission network in security, scalability and resource utilization, some problems have been exposed to the development and maintenance, network has brought greater pressure.Shijiazhuang Unicom transmission network after years of construction, the network has begun to take shape, especially wave division network has covered the Shijiazhuang local network in county level network. With the transmission of the constant enlargement of the network scale, network in the business of carrying capacity, scalability, maintainability, stability and safety and other aspects of the exposed problems. And wave division of high capacity, high compatibility, can be perfect to solve the network problems encountered. The most important point is the wavelength division equipment can greatly increase the cable resources utilization, can put the network cable resource utilization increase several times or even several hundred times. Therefore, the research on WDM is transmitted in a continuous construction and necessary work.This article mainly studies the WDM technology and its application, discusses the application of WDM technology case:Shijiazhuang Unicom WDM transmission network optimization research of Shijiazhuang Unicom, according to market development and business capacity demand, based on the WDM technology developed transport network optimization scheme, solving the problems of network development capacity, safety issues.I am mainly responsible for the Shijiazhuang Unicom transmission cyber source statistics and participate in optimization design, for Shijiazhuang Unicom east ring WDM system analysis, according to the Shijiazhuang Unicom equipment company Huawei WDM technique is presented in this paper the optimal scheme. Optimization of expansion after the wave division rings of single channel rate with the original 2.5G is promoted to 10G rate rate, And the wave of capacity expansion to become the 40*10G, greatly improve the east ring capacity and Dan Bo utilization rate reaches the expected purpose, for all subsequent WCDMA network and Internet capacity expansion to lay the foundation of.
