Researchers say they used a single five-mile cable to transmit twice the amount of data that's currently used by the entire Internet. While it could one day mean faster connections for users, the main benefit of the research could be more ... energy-efficient data centers. The project involved the Technical University of Denmark and the Chalmers University of Technology in Gothenburg. They explored the way most high-speed data connections today involve encoding signals to transmit as light. The key was combining a single laser with a specially-designed optical chip. This breaks the light into 223 ... (view more)
