Nokia said it achieved symmetric uplink and downlink speeds of 10 gigabits per second using hybrid fiber coaxial cable. The tests used a prototype technology called XG-Cable, based on applications developed by Bell Labs, which Nokia acquired through its $16.5 billion purchase of Alcatel-Lucent earlier this year.
The test was conducted in the 1.2 GHz spectrum band and used point-to-point cable topologies. Nokia said the tests show how existing cable systems can be used to deliver symmetrical broadband access services for businesses and consumers.
