BT core network speed tests smash world records

Speed test

Successful fibre optic network trials have seen BT and its partner Huawei score some other world first.

They’ve incontestable the quickest ever speeds of 2 Terabits per second (Tbps) over a live core network link.

The latest development Marks a leap forward since 2014, where BT used optical superchannels to accomplish 3Tbs over a closed trial network. Now that same technology has been applied to the commercial fibre link carrying live client traffic between London and Dublin – that’s a stretch crosswise more than 700km of cable.

BT proclaimed that it has besides pushed speeds of 5.6Tbps over a single optical fibre running on its trial network, surpassing the 3Tbps record set in 2014.

The speeds are the equivalent to transmission around 200 HD films in a single second.

The transmission was conducted over a link between BT’s Adastral Park research field in Suffolk and the BT Tower in London.

Howard Watson, CEO of BT Technology, Service & trading operations, said: “These landmark trials show that we can easily turn up the dial to deliver the speeds needful in our core networks to stay well ahead of rising client demand.”

Super speed

The results demonstrate how BT’s core fibre optic infrastructure could work even more expeditiously in the future, reducing the need to invest in more cables as information measure demands from consumers and businesses continue to grow.

By exploitation Terabit superchannels and flexible grid infrastructure, BT can increase the speed of its existing core optical networks without the threat of networks grinding to a halt when information measure limits are reached.

Howard said: “The core network is the superhighway of the net. It’s important that our core networks keep pace with the growth in information measure demands driven by take-up of high-velocity fibre broadband, HD content, 4G smartphones and tablets and in the future, 5G services.

So we’re investment in our core, as well as in high-velocity access technology so much as fibre broadband, to make sure there is no capacity crunch and deliver the best possible speeds to clients.”

Zha Jun, president of Huawei Fixed Network Product Line, said: “Ultra-High-Speed optical networks are an indispensable infrastructure for the future of digital life, and this is an area where Huawei is investment, to help telcos so much as BT squeeze as much capacity out of their core networks as possible."
