Scientists at Bangor University in north Wales have achieved fibre broadband speeds of 20Gb during testing, it has been claimed.
Researchers working on the Ocean project say they have achieved speeds 2,000 times faster than those offered by a standard broadband connection, reports the BBC.
And they are now working towards making this 'hyper-rapid' broadband an affordable proposition for homes and businesses.
Dr Roger Giddings, one of the researchers on the project, explained that the capabilities of fibre are increasing all the time.
However, he said it costs "a lot of money" to transfer data at such speeds, meaning the technology is some way from being commercially viable at present.
"The focus for the Ocean project is really to find out if we can do it in a cost-effective way," Dr Giddings stated.
"We hope to have a working module at the end of the three-year project, and we are one year into it at the moment."
