Bell Labs has taken the Internet speed limits to new heights by achieving a mind boggling speed 10 GB per second over traditional Telephone Copper cables. Bell Labs said it used two pairs of 30m (98.4ft)-long standard phone cables using a prototype technology it calls “XG-FAST,” the successor to its previous “G.fast” technology that is currently being ratified by the International Telecommunication Union. Usually this kind of speed is achieved through Fiber Optic only but Bell did am amazing job of making it possible through the Copper line. This means that now we can existing copper cables to boost the speed of the net rather than using expensive Fiber Optic technology.
The fastest speed however has been achieved using fibre optic cable link which was 1.4 terabits per second and that speed record was also accomplished by Alcatel-Lucent.
