Oki builds virtual network for 100-km broadband optical access service demonstration

ntttttttttttt

Oki on Monday announced the development of an adaptive network configuration technology and success in channel-switching between current GE-PON1 systems and the 10 GE-PON2 system, next generation high-capacity optical access. Based on improved functionality in optical line terminals and optical network units, the breakthrough results in a flexible, low-cost optical access system for subscription-based 100-km broadband optical networks.

Despite the rapid advance of FTTH (Fiber-To-The-Home), optical access systems based on current GE-PON systems provide a servicenrange limited to 20 km. Expanding this requires the installation of creating a “digital divide” in underperforming areas and sparsely populated regions, restricting users access to high-speed broadband.

Demand has also emerged in the area of subscription-based optical networks for the high adaptability required to respond flexibly to a growing subscriber base, as well as for various services and variable transmission capacity.

To address these issues, The National Institute of Information and Communications Technology (NICT; an independent administrative institution) in 2009 commissioned Oki to initiate research on subscription-based broadband optical network technologies that would enable broadband services without installing new center offices, based on virtualized connectionsnbetween optical line terminals and optical network units
