Epon Technology In The Broadband Network

With the increasing competition of the telecommunications market, the existing accessed building-mode broadband which make copper as transmission medium, based on asymmetric digital subscriber line (ADSL) technology-based that can not adapt to the future of surfing, high-definition video, safety monitoring of high-speed business bandwidth needs. And with the developing in depth of the broadband services market, fatal problems of the traditional broadband access in the internet speed, stability, construction costs, maintenance and management, market application, and so on have gradually exposed .At the same time, "light back into the copper" as the effective measures to the implementation of restructuring and fixed-line broadband network, will play an important role to improving access bandwidth, upgrading the capacity of support operations to the network, and enhancing the operators'capabilities of the core competitiveness.As a new access network technology, Ethernet-based passive optical network technologies (EPON) effective to alleviate the situation of the current severe stolen copper, prices rose faster and the increasing capital cost.In this paper, it's a review to the development of access network and the development of EPON technical at first, and introduced the EPON detailedly about the system structure and the Working Principle. Focuses on the key technology support EPON: Uplink transmission mechanism, Dynamatic Bandwidth Allocation and ONU discovery and registration etc., and EPON physical layer MPCP protocol. Pass a technical research to EPON and make reference to current EPON technique of applied mode, combine the analysis of local network present condition in Kaifeng City and the summary of the development trend, point to EPON the application deployment in this city carried on study and research and got more suitable origin the city connect into the applied mode of network reformation, service gets stripe at this city network and promote a company competition ability.Finally carry on summary, physically apply the problem in the process and put forward a suggestion to the EPON further application according to this city EPON.
