Wdm System In Hubei Telecom Backbone

Under the great demands of social development, the telecom industry mades rapid progress, which promotes the process of social life and life modernization. At the same time, the telecom applications enter the people's daily life, and become their essential tools. Technology and research on telecom , especially the basic theory of telecom network ,and the research of telecom network technology, network terminal gains more and more attention. But on the system application and network planning, further probe should be needed. From the current situations of Hubei Telecoms, this article takes systematic ways to plan the transmission network scheme.Part one Introduces the newly development of WDM,development trends of telecom services, the system structure of WDM, discusses the basic characteristics, planning ways of hubei backbone transmission network, analyses the development current situations of hubei transmission network and forecasts the relevant services;Part two Puts forward principles of telecom contructions and the problems that need considerations, then under the guide of the principles, makes thes constrution scheme of hubei backbone transmission network;Part three Puts forward the technological parameters of main telecom equipments, and through the theoretical anlysis and caculation, the main lines in the scheme are proved theoretically so that the scheme's maneuverability and practicability can be guranteed .
