Design Of Metropolitan Transmission Networks Construction Scheme In The Full Service Operation Mode

A full service operation competition pattern has taken shape for three main companies after the restruction of the mobile communication industry. The transport network is the fundamental network of the operators. How to react Full Services Operation smooth evolution from the existing network system to meet the development of the network and have higher cost performance at the same time is an urgent problem.This dissertation starts with the existing problems of the metropolitan transmission networks and put forwards the idea of constructing a new metropolitan transmission network in the Full Service Operation mode according to the changes of Bearer Service,Bandwidth Needs,Network organization and Terminal access. The various optical network technologies are analysised theoretically through relative method and analogism and the best scheme are choosen. The reliability and practicality of the scheme are verified by actual examples.
