EPON技术及其应用

On EPON Technology and Its Application

油田数字化与平安城市建设对接入网络提出了更高的要求。传统的ADSL、LAN、点对点光纤网等接入方式已无法满足数字化油田与平安城市对通信质量的要求。基于PON的以太网无源光网络(EPON)采用点到多点结构,无源光纤传输方式在以太网上能提供多种业务。EPON无源光网络经济而高效的结构成为了当前油田数字化与平安城市建设构建接入网络最有效的通信技术。

Digitization in oilfield and construction of restful city demand for higher net access.Traditional access methods such as ADSL,LAN and point-to-point fiber-optic net hasn＇t met their requirement for communication quality.Because Ethernet passive optical network（EPON） based on PON adopts a point-to-multipoint structure,passive optical fiber transmission is able to provide multiple operation over Ethernet.EPON,as a economical and efficient structure,has become the most effective communication technology for access network of oilfield digitization and construction of restful city.
