The "fastest ever" broadband speeds have been achieved in a test in London, raising hopes of more efficient data transfer via existing infrastructure.Alcatel-Lucent and BT said speeds of 1.4 terabits per second were achieved during their joint test - enough to send 44 uncompressed HD films a second.
The test was conducted on a 410km (255-mile) link between the BT Tower in central London and Ipswich.
However, it may be many years before consumers notice any effect.
But the breakthrough is being seen as highly important for internet service providers (ISPs), as it means a greater amount of information can be sent through existing broadband infrastructure, reducing the need for costly upgrades.
