Special Section on Next Generation Broadband Access Technologies

Existing broadband access systems include ADSL over metallic wires, optical media converters, B-PON, GE-PON, and G-PON systems. Recent innovations such as the higher speed systems of 10G-PON, 10GEPON, and WDM-PON are receiving a lot of attention, and low cost and mass production technologies for high speed wide bandwidth systems should be developed. New optical access network architecture also should be discussed to provide emerging services economically with higher security. In response, the IEICE Communications Society has organized this special section to analyze and resolve these technical issues.
