小区EPON接入方案的研究与设计(课题说明书,开题报告,中期检查表,论文12000字)
摘  要 伴随着因特网的日进爆炸式的发展，各种在因特网上的服务应用也进而迅猛发展起来。但用户必须使用某种方式接入网络才得以使用因特网上的多类服务。作为接入网技术之一的EPON特别适用于在光纤接入网的实践操作之中。并且现如今，一些早期传统的方式已不再适用于用户的一些服务要求。为了满足用户的要求，可以大胆猜测接入网的最终处理方法在未来为光纤到户。本文依次介绍了光纤接入技术、EPON、光纤入户等方面。这些都为本次的设计奠定了理论的基础。以太网无源光网络可以给予用户的所需的相关业务。光纤到户能够给予用户使用很大的带宽范围。从第四部分开始我们引入了基于小区EPON接入方案的实例并提供了相关的解决方案，包括设计接入网的网络结构、PON口资源的占用情况、设备选型、光网络单元的位置、光线路终端的容量等方面，体现了基于小区EPON接入方案的可行性，以此来满足该小区所需的业务。

Research and Design of Residential EPON Access Scheme
Abstract  With the explosive development of the Internet, various service applications on the Internet have also developed rapidly. However, users must access the network in some way to use the various services on the Internet. As one of the access network technologies, EPON is especially suitable for the practical operation of optical access network. And now, some of the early traditional ways are no longer applicable to some of the user's service requirements. In order to meet the user's requirements, we can boldly guess that the final processing method of access network will be fiber-to-home in the future. In this paper, optical fiber access technology, EPON, optical fiber household access and so on are introduced in turn. All of these lay a theoretical foundation for this design. Ethernet passive optical network can give users the related services they need. Fiber-to-home can give users a wide bandwidth range. From the fourth part, we introduce an example of EPON access scheme based on cell and provide relevant solutions, including the design of network structure of access network, occupation of PON port resources, equipment selection, location of optical network unit, capacity of optical terminal and so on, which reflects the feasibility of EPON access scheme based on cell, in order to meet the needs of the business of the cell.
