A Deep Analysis on the Key Techniques of 10G EPON

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 10 G EPON.
