More Data, Less Power

Posted November 18, 2010 9:00 AM by Steve Melito

Data-intensive services such as cloud computing and ultra-high definition (UHD) video can clog networks and increase electricity costs. So what does the future hold? According to Japan's Ministry of Economy, Trade and Industry (METI), networking equipment in 2025 will use 13 times more electricity than in 2006. That's unless serious energy-saving measures are achieved, and without the addition of any new network services that METI may have missed.

Fortunately, Fujitsu Laboratories just announced that it can cut the power consumption of an optical waveguide switch by 50%. The subsidiary of Fujitsu Limited plans to use fine-pattered silicon germanium (SiGe) to produce high-speed optical switches that will work across a wide range of wavelengths and feature the world's lowest power requirements. Because it has a narrower bandgap that silicon (Si) alone, fine-patterned SiGe accumulates electrons more efficiently.

Does this development pave the way for high-speed services that can connect cloud networks and provide UHD videoconferencing?
