The Research And Implementation Of EPON

The access network is a bridge between the backbone network and the end users. The access network has great importance in communication networks. Not only does the resource allocation of backbone rely on the access network, but it directly affects the usage of communication networks as well. The Ethernet based Passive Optical Network(EPON), which uses the mature Ethernet Protocol and equipment, has no need to make protocol conversion between IP and ATM as APON Does. With low cost, low overhead and high bandwidth utility, EPON Has became one of the promising approaches of broadband access.Firstly, this thesis introduced the development of the access network, the definition of the optical access network. Analyze the characteristics and advantages of EPON.Proceeding from definition of EPON system, we introduce structure of...
