摘　　要：EPON网络是采用FTTB方式组建网络,其组网基本单元为OLT和ONU.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.对于不同业务的接入实现主要是采用对不同用户不同业务打不同的VLAN标签来透明传输到相应的业务接入服务器,并将相应的VLAN标签剥离后送入IP承载网传输.EPON network is built by means of FTTB,the basic networking units are OLT and ONU.OLT provides equipment of central office with broad PON interfaces to connect ONU equipment,ONU realizes the user service access by corresponding data and voice interfaces provided by the user equipments.Different user and different service are labeled with VLAN,they are transparently transmitted to business receiving server,then it is send into IP supporting network with the VLAN tag peeled off,so the different service access is finished.
