摘　　要：随着智能电网、三网融合、网络视频等高带宽业务需求的不断增长,1 G EPON网络向10 G EPON升级已是大势所趋。文章首先介绍了10 G EPON系统标准的最新进展,然后对10 G EPON系统波长分配、FEC、光功率预算、MPCP等关键技术进行分析,最后结合智能电网信息通信业务对EPON网络的需求,论述1 G EPON向10 G EPON平滑演进的方式。With the continuous increase in bandwidth demand generated by smart grid, triple-play, IPTV applications, 10 G EPON becomes an effective way to meet performance demands in access networks. In this paper, we first introduce the standardization status of 10 G EPON system, and then we discuss the key features of 10 G EPON systems, including wavelength allocation, FEC, optical power budget and MPCP. Finally, considering the information and communication service requirements of smart grid, we discuss the smooth migration from 1 G to l0 C, EPON.
