Design of access network system based on 10G EPON

Improvement and advantages of 10G EPON hierarchical model, which had been standardized in the framework of the IEEE 802.3av Task Force, are analyzed. Based on the analysis, the related upgrading technique scheme of 1G EPON to 10G EPON as well as the corresponding technical key bottlenecks of dynamic bandwidth allocation (DBA) mechanism and security problems are thoroughly studied. Furthermore, three kinds of networking schemes based on 10G EPON systems are proposed, which can respectively be suitable for different situations of FTTH, FTTO and mobile communications. At the same time, these schemes can support various triple-play services and effectively integrate the computer communication with telephone and video services, providing a good reference for future 10G EPON access network system.
