1、浙江大学硕士学位论文 AbstractiEPON 在用在用户户接入网的接入网的应应用研究与用研究与实现实现摘要 本课题“EPON 在用户接入网的应用研究与实现”是采用 EPON (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)“
2、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
3、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。由于现有商业楼宇组网结构复杂、不便于管理、需要固定机房、建设成本高等问题，特提出了将 EPON 应用于商业楼宇的方案，总结了业务应用模式，方案有效解决了现有商业楼宇组网方案的种种弊端。同时，也提出了将 EPON 应用于小区的方案，由于现有 ONU 的成本相对较高，因此FTTH+LAN 是较好的选择，该接入方式的建设成本与 ADSL(Asymmetrie Digital S
4、ubscriber Line 不对称数字用户线)基本相同，但系统效率明显增强，因此可以考虑逐步替代 ADSL 的接入方案。最后，为验证 EPON 应用方案的可行性，确保 EPON 系统在业务提供、系统浙江大学硕士学位论文 Abstractii性能等方面能够满足业务的需求，本章还描述和总结了参与 EPON 系统测试的整体情况，包括测试配置、内容和结果。论论文主要特色文主要特色通过查找、搜集的大量宽带接入网相关资料，对 EPON 的技术发展、与其他接入技术的比较与功能进行了详细的介绍；深刻研究了 EPON 的原理结构、相关协议及主要关键技术；根据查找资料，结合工作经验，总结 EPON 在工程实施中
5、的设计要点，提出EPON 接入网方案；以工作中实际工程为案例，具体说明 EPON 在用户接入网中应用，提出EPON 技术在不同接入模式的设计方案。提出 FTTH+LAN 的新型组网模式，既实现 EPON 的高带宽、高速率、易管理等优点，又解决 ONU 投入成本高的问题，是目前可行的接入网建设方案；在实验室进行试验，对 EPON 系统、互联互通进行了测试，论证了应用方案的可行性，EPON 技术已经比较成熟，各项性能指标能够满足现有网络的应用需求。关关键词键词：以太网无源光网络，光纤到户，光网络单元，光线路终端，光配线单元浙江大学硕士学位论文 AbstractiiiAbstractThe issu
