epon在用户接入网的应用研究与实现大学毕业（设计）论文.doc

硕士毕业论文 EPON在用户接入网的应用研究与实现 摘要Ethernet Passive Optical Network以太网无源光网络)宽带光纤接入技术实现FTTH (Fiber ToThe Home光纤到户)、FTTB (Fiber ToThe Building光纤到楼)、FTTO (Fiber ToThe Office光纤到办公室)等方案，从而实现数据、VoIP (Voice over Internet Protocol语音)和IPTV (远程视频)“三网合一”的业务带宽需求。并且具有一定的运行、维护和管理功能。 论文第一部分介绍了EPON技术在国内外的发展情况，PON技术的发展过程，PON的标准现状，综合比较EPON与GPON (Gigabit Passive Optical Network千兆无源光网络)的优缺点；根据国外EPON的发展规律，论文制定了EPON在中国的业务预测模型；并详细描述了EPON的基本原理、关键技术和技术优势。 第二部分分析EPON在用户接入网的应用。首先分析研究EPON的组网应用，总结分析EPON在工程实施中的设计要点，包括OLT的部署方案，ONU部署方案以及分光器的布放方式和原则；然后列举典型住宅小区、工业区、别墅区和边远山区的接入方案。 第三部分是本文的重点，结合具体工程实例，提出并验证FTTH、FTTB、FTTO等接入模式的实现方案，研究探讨了EPON在运营商网络运营中的不同建设模式。Asymmetrie Digital Subscriber Line 不对称数字用户线关键词：以太网无源光网络， Abstract The issues that The Research and Realization of EPON Application in Access Network adopts the technique of Ethernet passive network . It can realize the triple-play business of data, VoIP and IPTV , It can also have the function of certain operation , maintain and management . The first part of paper describes EPON technology development at home and abroad, the development process of PON, the standards of EPON, comparing EPON and GPON (Gigabit Passive Optical Network) the advantages and disadvantages; foreign EPON in accordance with the laws governing the development of EPON thesis developed in China forecast model; and a detailed description of the basic principles of the EPON, the key technical and technological superiority. Analysis EPON access network applications in the second part of paper. analysis of the implementation of EPON in engineering design features, including the deployment of OLT program, ONU, as well as the deployment of the programs deployment spectrophotometric methods and principles; and then cited a typical residential district, industrial district, the villa area and remote access program of the mountains. The third part is the focus of this article, examples of specific projects and put forward and verified FTTH, FTTB, FTTO access patterns,
