With the increasingly fierce competition in the telecommunications market, the existing copper cable transmission medium, based on asymmetric digital subscriber line (ADSL) technology based on the construction of broadband access mode to carry out high-definition video, security surveillance, and other rates will be unable to meet future bandwidth services. \This article by the introduction of the principle of FTTH' dissertation">FTTH technology to analyze the characteristics of FTTH technology and compare with other access technologies, proposed FTTH access technology advantages and prospects, and as a basis for comparative analysis of P2P and P2MP (PON) FTTH achieve the technical principles of the way, from the perspective of technical principles, networking, technical maturity APON, EPON, GPON three kinds of PON access technology for detailed analysis obtained using EPON technology as the access network program . EPON will combine Ethernet passive optical network (PON) technology, its goal is the easiest way to achieve a point-to-multipoint topology Gigabit Ethernet fiber access network. EPON belong to the IEEE Ethernet standard areas for the transition to all-IP networks is a good choice. EPON reduce initial costs and operating costs, extensive use of Ethernet technology is mature chip, simple, relatively low cost, simple to maintain, easy to expand and easy to upgrade. This article focuses on the evolution of the up and down the line works in EPON protocol stack, key technologies and technical principles as well as in the standardization of EPON EPON networking solutions in different scenarios (FTTH, FTTB, FTTN) selection. Based on the strategic value of the FTTH access technology, combined with Guangdong Telecom Company \characteristics of the project, select the appropriate mode of construction, this project examples demonstrated early to explore the feasibility of the construction of subdivision EPON network planning model was in accordance with customer demand, as well as OLT equipment, ONU equipment, ODN network planning were discussed with the implementation of the demonstration, and the design of specific networking solutions, including system design, equipment selection, application assessment, focusing on the system design elaborate.
