Passive Optical Network Technology And Its Application In Xinyu Telecom Access Network

With the sustained and rapid development of Internet, network HDTV, 3D video, backup and disaster recovery, cloud computing and other large flow, multi demand of broadband services emerge in endlessly, to meet the family unit and the user demand for bandwidth to achieve 100Mbps-10 Gbps. Operators on the basis of this, put forward the "light into copper back" access layer network deployment concept, to the user "the last mile" to achieve fiber access ", the current EPON and GPON technology capabilities can provide each user 10-20 M bandwidth, the basic can meet the needs of the current stage and the next 2-3 years. But in the long run, the bandwidth and the ratio of light and light are still unable to meet the needs of50M-100 M development in the future. The next generation of PON technology has been studied.Firstly, this thesis makes a comprehensive analysis on the principle and key technologies of PON network. Then, according to business requirements, the paper gives a detailed description of the evolution of the next generation PON system, compares the application scenarios of different versions of PON and NGPON1 in PON development, and analyzes the current situation and demand of local access network. In the end of this paper, we design the PON PON reconstruction scheme based on PON net and 10 G net.
