New FTTH Technology Radically Cuts Energy Use

AMSTERDAM - GreenTouch, a global consortium dedicated to improving the energy efficiency of information and communications technology networks, is demonstrating a new technology that it says will dramatically reduce energy consumption in fiber-to-the-home networks, wireless backhaul and other applications.

GreenTouch's Bit-Interleaved Passive Optical Network (Bi-PON) technology will enable a power reduction of 30 times over current technologies [note: other information from Greentouch estimates this reduction at 10 times - from 2 watts to 200 milliwatts per ONT], while at the same time improving performance and reducing cost. This breakthrough is possible, according to GreenTouch, because today's optical network units discard 99 percent of all processed data without ever using it. Bi-PON uses a selective data processing technique that dramatically reduces this energy consumption.

FTTH deployment is expected to nearly double over the next five years, reaching 142 million subscribers worldwide by 2016, according to ABI Research. At the same time, new standards will allow speeds of up to 40 Gbps. By using Bi-PON instead of the current optical technology, deployers can have an impact on the carbon footprint equivalent to taking half a million cars - all the cars in San Francisco - from the roads.

GreenTouch member companies imec, a research organization in nanoelectronics and nanotechnology; INRIA, a French public research body dedicated to computational sciences; Orange Labs, the research and development center of France Telecom-Orange, one of the world's leading telecommunications operators; and Bell Labs, the research arm of Alcatel-Lucent, will participate in today's worldwide demonstration event.

The demonstration will show live video traffic flowing through two separate networks - a standard optical network and a Bi-PON-enabled one - both attached to a power meter that will measure the energy consumption and reveal the dramatic decrease in energy consumed in the Bi-PON over traditional XGPON and XGPON operating in sleep mode.

GreenTouch has now developed and demonstrated two technologies, today's Bi-PON announcement and the Large-Scale Antenna System first demonstrated last year. Together, these technologies will improve energy efficiency by more than a factor of 25. More importantly, GreenTouch's first two demonstrations illustrate a path toward much higher gains that will be realized in future research demos. GreenTouch is also actively working on developments across its 25 projects and aims to have new demonstrations in the coming months that will help the consortium reach its goal of creating technologies that will make ICT networks 1,000 times more efficient. A thousandfold reduction is roughly equivalent to being able to power the world's communications networks, including the Internet, for three years using the same amount of energy that it currently takes to run them for a single day.
