The Design Of Broadband Access Network Based On PON Technology

The broadband network construction the biggest bottleneck is the broadband access network, broadband access network in the broadband network plays a very important role. It not only affected the broadband backbone cyber source configuration, but also directly related to the user on the use of broad band network. Among the many network scheme, based on Ethernet passive optical network (EPON) network with other incomparable advantages, he made full use of Ethernet mature protocol and equipment, low construction cost, convenient maintenance, and greatly improves the utilization rate of the network bandwidth. Passive optical network (PON) using the tree topology, can achieve the Ethernet service, video service and the TDM service high speed transmission, is the current broadband access network in one of the most popular broadband technologyBased on theoretical analysis and comparison of broadband access technology, it is easy to see that the EPON technology in broadband access has a great advantage, he can give the user to provide a more stable and reliable access to services. In practical engineering applications, the EPON technology has become the telecom operators using EPON technology in broadband access network transformation is the preferred technique, he not only to solve the traditional scheme to solve the problem, and low investment cost, network stability, easy maintenance, has very broad application prospects.This paper from the broadband access network development present situation and the development trend proceed with, a detailed analysis of the technical characteristics of EPON and technical advantages, the research of EPON system structure and working principle, the design of a EPON based broadband access network solutions, and the project carried out a feasibility study, carried out a detailed program design. According to the design scheme of EPON system, specific to each part of the system configuration and function realization, forming a low investment, stable operation, but operation of telecom broadband access network.
