西北工业大学明德学院本科毕业设计论文 摘 要 信息产业是当今世界经济领域中最具有活力和竞争力的产业之一，它影响着人类的生活方式和生活质量。接入网是用户网进入城域网/骨干网的桥梁。随着SDH技术的大规模推广应用和ATM技术的发展，电信网的主干网已经基本上实现了光纤化、宽带化和数字化。 关键词：接入网，光纤通信，PON - 1 - 西北工业大学明德学院本科毕业设计论文 ABSTRACT Information industry is the world’s economy the most dynamic and competitive industries in the world, it affects the way people live and the quality of life. Access network is the user network access to metro/backbone bridge. With the popularization and application of SDH technology and large-scale development of ATM technology, telecommunications network backbone has been basically realized fiber, broadband and digital. Firstly, an overview of access network technology. By definition, the physical reference model, access technology, trends and other related content outline indicating the access network, optical access network is the inevitable trend of technological development. Secondly, this in-depth study of the copper access and optical access to both the access network access technology, and focused on particular passive optical fiber access networks (PON - Passive Optical Network) and the current mainstream FTTx (Fiber To The x/some place) .Then, the paper quot;Light of Copperquot; solution for specific research and analysis. mainstream operators first kilometer access networks are still largely dominated by twisted pair copper network, in order to meet the growing bandwidth demand, to achieve optical access, the existing copper access network must be modified. Finally, on the optical access network technologies are introduced, consistent with TMN requirements about the access network management system structure and function, and the realization of the access network of network management.
