With the backbone of the ability more enhancement， meanwhile access but not much progress. So， by backbone network to user terminals between several hundred meters or a few kilometres of access network， thus has been aptly called the 。last mile。. Because backbone by using optical fiber structure， basic transmission speed very fast. Therefore， the 。last mile。 will inevitably become the bottleneck of restricting the entire network system. This makes the improved access network has reached the crucial time. This paper briefly introduces a series of basic knowledge about EPON and EPON for the access method and the district access network planning. Based on practical principles， comprehensive consideration of the equipment selection， ONU position， IP address allocation， realize its operational sex. And selected a village， the full optical fiber access network design， achieve the purpose of skills to use.
