Abstract


Although in recent years the rate of transmission network communication can be greatly improved, but the user access to the network transfer rate is still very limited , the rapid development of the Internet and the future of things to achieve further expansion of this gap , the \and large -capacity high-speed LAN backbone transmission bottleneck between . Optical fiber as the transmission medium of fiber to the home (FTTH) in transmission bandwidth advantages , making each operator to develop the direction of the passive optical network (PON) technology for its line resources saving , convenient operation and maintenance , equipment costs low many advantages , by many telecom operators are using. This article first FTTH technology development direction and trends at home and abroad are described. FTTx defined in the introduction , based on the analysis of the construction of FTTx broadband access mode and the construction mode. Expounded the principle of PON technology and network architecture , and the two current mainstream PON technology : Ethernet Passive Optical Network (EPON) and Gigabit Passive Optical Network (GPON) were classified comparison , then introduces the PON technology implementation process Selection of the appropriate components and the use of access scenarios were classified, and made a PON network construction, a number of issues that need attention . Finally focuses in Sanmenxia City , a lot of the new district or the use of traditional digital subscriber line access multiplexer (DSLAM) for network construction, this model is not only the high cost of construction , low bandwidth , operation and maintenance of complex , difficult construction , economic and efficiency is also poor , unable to meet future bandwidth requirements of triple play . So for Sanmenxia City Haicheng District , the White Swan Inn two new projects to carry out inspections on its user's situation , pipeline resources , pole road resources , bandwidth requirements, and edge node deployment site selection and other key data for a detailed calculation and analysis . Abandon the traditional DSLAM network construction model presents a suitable existing network system can be operated FTTx network construction mode ; through engineering and economic analysis of technical indicators , the project not only solve the high cost, low bandwidth , operation and maintenance of complex , difficult construction problems, economic and social benefits has also been significantly improved, so that it can better adapt to carry out triple play services .
