Analysis Passive Optical Network Practical Application In Fttx

Although in recent years the rate of transmission network communication greatly improved, but user access network transmission rate is very limited, rapid development of Internet and the future content networking can realize further expanded this gap, the "last mile" is still transfer bottleneck between high-speed lans and large capacity backbone. By optical fiber for transmission medium of FTTH (FTTH) in transmission bandwidth advantage, make it become at various operators vigorously develop target, passive optical network (PON) technology for its saving line resources, convenient operation and maintenance equipment, low cost and so on, used by numerous telecom operators.This paper firstly expounds the FTTH developing direction and trend of both at home and abroad.Then the paper introduces the definition of FTTX and makes some briefly summarize for the building mode of several FTTX. Then on to broadband access construction mode summarizes briefly and carries on the analysis, this paper expounds the principle and PON network structure, and to the current mainstream of two PON technology: the EPON and GPON classification comparison, and emphatically introduces in PON technology implementation what the needs are components, then on to access scenes for the classification, and put forward the PON network construction several problems needing attention.Currently in urban area of SanMenXia, many new district are using the traditional DSLAM network construction,the construction model not only the high cost and the construction difficulty, economic benefit is relatively poor, cannot satisfy the next three net fusions of bandwidth needs. So this paper for Haicheng village,the white swan hotel on field investigation and quick to its users,pipe resources,such as bandwidth needs and brim nodes deployment to the choice of the key data carry on the detailed calculation and analysis. Among them because of the construction of the coordination problems, and put forward the construction scheme of network has carried on many times the revision, and finally put forward a suitable for now the operational network FTTX system structure scheme;the scheme not only solves the high cost and the construction difficulty problem, economic benefit and social benefit increased significantly, make can better adapt to three net fusions business launched.
