沈阳工程学院毕业设计（论文） 业务实现原理 沈阳工程学院毕业设计 摘要 -  PAGE II -  PAGE I 摘 要 网络融合实现全业务接入已经成为接入网发展的必然趋势，EPON技术在接入速率、带宽效率、分光比和全业务承载能力以及安全性方面都具有明显优势从而成为光纤接入时代的优选技术。 EPON网络以 HYPERLINK /tech/%B9%E2%CF%CB \t _blank 光纤为 HYPERLINK /techClass0 \t _blank 传输媒质，使用以太网协议作为网络传输协议，利用PON的拓扑结构实现数据、语音及视频的综合业务接入。EPON系统主要由OLT（光线路终端）、ONU（光网络单元）和ODN（光分配网）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实现。EPON网络是采用FTTB方式组建，从OLT到ONU采用WDM技术实现单纤双向传输，并使用不同的VLAN标签来标记相应的用户业务流量。 本文通过一个小区用户实际业务需求为案例，合理规划相应用户业务数据新建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400用户提供电话和宽带业务服务。 关键词 以太无源光网络，光线路终端，光网络单元 沈阳工程学院毕业设计 Abstract 沈阳工程学院毕业设计 Abstract  PAGE II Abstract Using network convergence to achieve full-service access has become an inevitable trend of the access network. EPON technology takes advantages in the access speed, bandwidth efficiency, the load-bearing capacity of whole business and security which obviously becomes the preferred technology in access times. EPON network take fiber optics as the transmission medium, using Ethernet protocol as its network transmission protocol, taking the PON topology to realize the integrated services of data, voice and video access. EPON system is mainly composed by the OLT (Optical Line Terminal) which provides a lot of PON equipments to connect ONU equipments, ONU (Optical Network Unit) which provides the corresponding data and voice user interfaces to achieve service access and ODN (Optical Distribution Network). EPON network is formed in the way of FTTB, which using WDM technology to achieve two-way transmission between the ONU and the OLT. It uses different VLAN tags to identify various of users access traffic. By studying the actual business needs of a cell, according to the business data this paper rationally designs
