If you thought your broadband was fast then get a load of the speeds reached by BT and Alcatel-Lucent in London.
The trial, conducted jointly between BT and Alcatel-Lucent, saw broadband speeds reach a whopping 1.4Tbps (terabits per second). That's enough to transfer 44 HD films in one single second.
The speed is thought to be the fastest ever achieved using commercial grade hardware and a real-world environment. The test was conducted over a 250 mile distance between the BT Tower in London and BT's Adastral Park research campus in Suffolk.
Although consumers may not see the benefits for a while, the key takeaway is that these speeds were achieved on an existing fibre core. This means that in the future ISPs (internet service providers) will be able to offer higher speeds without needing to spend large amounts on network upgrades.
"This could allow BT to more easily scale its core network capacity to meet consumer and business demands for more bandwidth-hungry services such as streaming video, whilst more efficiently using its existing core fiber infrastructure." said Alcatel-Lucent.
This is good news looking forward with the increasing popularity of internet services, especially video streaming such as Netflix and Sky's Now TV. Broadband will be under more strain as 4K technology is pushed to consumers.
The firms used a Flexgrid (flexible grid) infrastructure to vary the gaps between transmission channels. The trial was conducted through the overlaying of an 'Alien Super Channel' comprised of seven 200Gbps (Gigabits per second) channels bundled together. The firms saw a record spectral efficiency of 5.7 bits per second per Hertz (b/s/Hz).
