10Gbps downloads and uploads over cable demoed by Bell Labs

The cable industry R&D consortium CableLabs announced a plan for full duplex technology in February, and the Nokia-owned Bell Labs yesterday said it has achieved 10Gbps symmetrical speeds in the lab in a “world-first” demo.[…] The technology is still in the proof-of-concept stage and requires fiber to be built most of the way toward homes, relying on cable for the final stretch. This isn’t a huge barrier because cable networks already use a lot of fiber. “By leveraging the XG-CABLE technology, operators can effectively use existing HFC [hybrid fiber-coaxial] cables over the last 200 meters to provide upstream speeds never before achievable due to the limited spectrum available,” Nokia said. – Jon Brodkin, Ars Technica
