Alcatel-Lucent teams with BT for "fastest ever" 1.4Tbps broadband test in London

BT and Alcatel-Lucent claim to have achieved the "fastest ever" broadband speeds in a test conducted in London.

According to the two firms, the joint experiment attained speeds of 1.4 terabits per second – fast enough to transfer 44 uncompressed HD films in a second.

Fibre cable technology that has already been introduced to much of the UK was used to achieve the results.

This is particularly good news for Internet service providers (ISPs), since it confirms that existing broadband infrastructure can be made much more efficient than it currently is. In turn, this will reduce the need for expensive, time-consuming upgrades.

However, it could be a long time before everyday consumers benefit from the breakthrough.

Quicker data transmission technologies are in existence, but this test was the first of its kind to reach such impressive speeds in "real-world" conditions, according to Alcatel-Lucent.

"BT and Alcatel-Lucent are making more from what they've got," said Oliver Johnson the chief executive of broadband analyst firm Point Topic. "It allows them to increase their capacity without having to spend much more money."

Alcatel-Lucent told the BBC that demand for increased bandwidth has risen by 35 per cent on a yearly basis and has subsequently fuelled demand for more efficient ways to shift data.

The UK's rollout of superfast broadband has been widely criticised over recent months, however, IDATE's Pierre-Michel Attali recently assured ITProPortal that our introduction of the service is not yet doomed.

BT and Alcatel-Lucent carried out the trial on a link between Ipswich and the BT Tower in London.
