The massive speed increases were made possible by building customized amplifiers to boost signal power

Researchers in London have created the fastest-ever internet connection, much quicker than any ever successfully tried before.

The team at University College London (UCL) used amplifiers to enhance the way light carries digital data through fiber-optic broadband to achieve a record 178 terabits per second which are approximately three million times faster than the average UK home connection.

The connection is so fast that it would be able to download the entire Netflix library in just one second.

Dr Lidia Galdino, lecturer in electrical engineering and also a Royal Academy of Engineering research fellow has led the research team at a lab in Bloomsbury.

Galdino says that such “ultra-broadband” will be able to support the next generation of internet, while also back mobile 5G networks used by data-draining applications such as driverless cars and smart cities infrastructure, The Express Tribune reported quoting The Evening Standard.

The new record was achieved by transmitting data in a greater range of colours than is typically used in optical fibre in order to increase the bandwidth.

Galdino did a speed test by sending computer-generated bits in a 25-mile fibre optic loop around a Bloomsbury lab.

The massive speed increases were made possible by building customized amplifiers to boost signal power, which would be needed at least every 25 miles if deployed commercially.

It meant her super-speeds - the equivalent of 178 million megabits per second - were about 2.8 million times faster than the Ofcom-rated average 64mbps British home broadband connection.

“I managed to achieve the highest bandwidth that has ever transmitted through the internet,” Galdino told The Evening Standard.

“It’s important because internet traffic and data has been increasing exponentially over the last 10 years but we have reached the theoretical limit,” she said.

"The one other way to increase the capacity in optical fibre is increasing the range of wavelengths and colours that we can use, which is exactly what I’ve done,” Galdino added.

“This is underpinning the next generation of communication systems,” she said.
