As video consumption and total Internet traffic rises, even current fiber technologies such as GPON will not be able to keep up with the increased demand. Luckily, the Full Service Access Network (FSAN) and the International Telecommunication Union (ITU) are rising to the challenge by firming up their standards on NG-PON2, which promises speeds over 10x that of current PON technologies. This post reveals three exciting characteristics of this emerging access technology.
