Anyang Epon Access Network Construction Scheme Research

FTTx technology and application of rapid development, it has become the international within the scope of the technical hot, China unicom has also actively into EPON test and construction, I participated in anyang unicom EPON project test and construction and implementation work, including EPON laboratory and field test scheme and test and implementation, this paper derived from this enterprise project.This paper firstly introduces based on Ethernet passive optical network, this paper summarizes the current main PON FTTx technology, the standard present situation, and briefly describes EPON realization principle, key technology and technological advantages. Describes especially China telecom as telecommunication operators in EPON construction of set standards.This paper is focused on the analysis in the user access network EPON applications. To access network analysis of the current situation, summarizes the business application mode, introduces China unicom as access to the main means EPON to reference standards, compares different EPON equipment in user access network scheme, professional ability of the differences.This paper summarizes the key points in EPON implementation process, and explains the device type, business ONU types, such agreement calls for engineering implementation, the elements, in order to verify the feasibility of EPON applied to access network, we have single system and EPON interworking different types were tested and papers on the purpose of testing, test environment, solutions and results is described in detail, test for analyzing EPON in the realization of business buildings business to provide a reference and basis.Fiber-optic access is access network development trend, the current EPON technology already gradually mature, and costs continue to drop, the perfect function at home and abroad, are already widely used, EPON technology will increasingly been applied.
