Design And Realization Of EPON Technology In The Communication Access In Residential District

With the rapid development of information technology, as well as the national "tripleplay","copper back into the light" development strategy is under the impetus of thecommunication by means of access, residential area on the base of the traditional DSL, LAN isderived on the XPON technology.In this paper, the Changqing Oilfield Community as an example, analyzedand compared from the aspects of communication access business requirements, constructioncost, operation cost and the future development, select the EPON technology to solve the lastmile accessarea. The structure and principle of EPON technology, application mode,designscheme and system test are analyzed and studied deeply.In the aspect of technology selection, this paper uses the comparative analysis method,from the aspects of technical, cost, and maintenance, they are combined with the applicationof performance and trend of development, the EPON technology has an obvious advantagecompared with other technologies in the area of communication access network in china.Inthe engineering design, this article is maily about the EPON system of business,data ofplanning, configuration of hardware resources of OLT, combined with the actual needs ofresidential construction of ONU, ODN, they can achieve the scheme of network system andbusiness system.In the system test, the test and field service verification and other means,thevalidation and test the performance of the system and the businessindex.The results show that the EPON application system construction not only has obviousadvantages, but also it can reduce the cost in the aspect of construction, Operation andmaintenance, which are less than the traditional LAN, DSL technology in order to save thehuman resourses and financial input and meet the business, high current requirements in thebusiness, which can achieve the real implementation of the network data, voice, TV.
