摘　　要：有线网络传输的介质主要是金属导体和光纤导体,光纤因其简便实用,价格低廉的特性被广泛采用。EPON做为PON技术的一种,采用点到多点结构、无源光纤传输的特点,可在以太网之上提供多种业务被广泛应用。本文以浙江省某中学智慧校园工程为例,介绍了EPON技术的整体构架、主要设备组成、设计原则、安装调试过程中的注意事项等,并对比传统网络分析EPON网络的优缺点,为该技术在此类项目中的应用提供借鉴和参考。。Transmission medium is mainly metal conductor and optical fiber conductor,optical fiber because of its simple and practical,low-cost characteristics are widely used.As one of PON technologies,EPON is widely used to provide a variety of services over Ethernet by adopting the characteristics of point-to-multipoint structure and passive optical fiber transmission.Taking the project of a high school's intelligent campus in Zhejiang province as an example,this paper introduces the overall framework of EPON technology,the composition of the main equipment,the design principles,the matters needing attention in the process of installation and debugging,etc.,the advantages and disadvantages of traditional network analysis EPON network are compared to provide reference for the application of this technology in such projects..
