摘 要
接入网（Access Network，AN）是电信网的一个组成部分，负责将电信业务透明地传送到用户，也就是说，用户通过接入网的传输能灵活地接入到不同电信业务节点上。随着网络的演变和用户需求多样化的发展，接入网经历了铜线接入方式、光纤接入方式、综合接入网方式等多个网络发展时期。接入网已成为通信发展的一个重点。
其中，光纤接入网是目前应用比较广泛的接入技术之一，而光纤接入技术中的EPON技术又是一种新兴的宽带接入技术。它通过一个单一的光纤接入系统，实现数据、语音及视频的综合业务接入，具有良好的经济性。EPON系统主要由OLT、ONU和ODN组成。OLT为局端设备，提供丰富的PON口用于连接ONU设备，ONU是用户端设备，提供相应的数据和语音接口实现用户业务的接入。业内人士普遍认为，FTTH 是宽带接入的最终解决方式，而EPON 也将成为一种主流宽带接入技术。
本文主要介绍了用华为OLT和ONU设备来完成EPON接入网的设计及相关原理。文中以一个小区用户的实际业务需求为案例，合理规划相应用户业务数据并新建EPON接入网络。通过对OLT和ONU设备进行相应的硬件和数据配置，为小区内480个用户提供语音业务和宽带业务服务。

Abstract
Access network (Access Network, AN) is a part of the telecommunication network, which is responsible to transmit telecommunication business between equipments and users, namely, the users can access flexibly to different telecommunication nodes by transmission of access network. With the evolution of network and the development of users’ various needs, access network has gone through different period of development such as copper access, optical access, integrated access network. Access network has become a focus on development of communication .
Optical access network is one of the access technology , which is made widely use, the EPON technology is a burgeoning broadband access technology in fiber access network. It can accomplish access of integrated business such as data、voice and media in a single fiber, so it has good economy. EPON system consists of OLT, ONU and ODN. OLT is the central office device, it can provide various PON interface for connecting with ONU, ONU is placed to the users’ terminal in order to provide corresponding interface of data and voice to accomplish access of consumer business. The experts generally believe that, FTTH is the ultimate solution of broadband access, and EPON will become a main broadband access technology.
This paper introduces primarily how to use OLT and ONU of Huawei Co.,LTD to accomplish the design of Ethernet access network and the related theories. In the text, user's actual business requirement as example, Reasonably Ethernet access network is planned and built. At the same time, we provide voice and broadband business for 480 users in the district through configuring appropriate hardware and data for the OLT and ONU.
Keywords access network， Ethernet optical network，optical line terminal，broadband access
