Research division of Alcatel-Lucent, Bell Labs, announced a new record in the field of wired data transmission: the developers have managed to reach a speed of 10 Gbit / s using traditional copper telephone wires. Also shown was a prototype technology, so the existing network of copper wires can be used to provide services symmetric broadband at a speed of 1 Gbit / s. Symmetry means that the speed of 1 Gbit / s can be achieved simultaneously in the user side, and from it.
Bell Labs used a technique called XG-FAST, which is an extension of the standard G.fast, which is engaged in the development of the International Telecommunication Union (ITU). Standard G.fast will be introduced in 2015, it will be used for data transmission range of 106 MHz, and claimed it for the speed of 500 Mbit / s at a distance of 100 meters. XG-FAST, in turn, involves a range of 500 MHz to reach higher speeds, but at shorter distances: for 1 Gb / s copper wire length should not exceed 70 meters, for a 10 Gb / s - 30 meters.
In the long term development of Bell Labs will be an alternative to fiber optic lines if their use for technical or economic reasons is difficult. Related Products :
