Researchers Achieve Record Data Transmission Speed, 4.5 Million Times Faster Than Average Home Broadband

Researchers at Aston University have achieved an extraordinary feat by transmitting data at a staggering speed, surpassing average home broadband rates by 4.5 million times.

According to the researchers, this remarkable accomplishment marks the fastest data transmission ever recorded. It was made possible by tapping into previously unused wavelength bands within fiber optic systems.

301 Terabits Per Seconds

Researchers reported transferring data at a rate of 301 terabits per second, equivalent to a staggering 301,000,000 megabits per second, utilizing just a single standard optical fiber.

This achievement dwarfs the average broadband speed reported by the UK's Ofcom in September 2023, which stood at a modest 69.4 megabits per second.

Professor Wladek Forysiak and Dr. Ian Phillips, affiliated with the Aston Institute of Photonic Technologies, played pivotal roles in this groundbreaking endeavor.

Teaming up with researchers from the National Institute of Information and Communications Technology (NICT) in Japan and Nokia Bell Labs in the U.S., they spearheaded efforts to push the boundaries of data transmission capabilities.

With the burgeoning demand for data, the newly developed technology promises to address future data requirements effectively. Leveraging optical fibers-minute glass strands that convey information via light, researchers harnessed the potential of these fibers, which far outstrip the data-carrying capacity of conventional copper cables.

The key to this remarkable achievement lay in unlocking untapped wavelength bands within fiber optic systems. By expanding into novel wavelength bands, equivalent to different colors of light transmitted through optical fibers, the researchers could significantly enhance data transmission capabilities.

This breakthrough was facilitated by developing devices, such as optical amplifiers and optical gain equalizers, designed to access these previously unutilized wavelength bands.

Dr. Phillips spearheaded the development of a management device optical processor at Aston University, instrumental in orchestrating the seamless transmission of data through optical fibers.

"Greener Solution"

Dr. Phillips noted that the data transmission process resembled that of a typical home or office internet connection. However, what set this endeavor apart was the utilization of additional spectral bands-E-band and S-band-beyond the conventional C and L-bands.

Professor Forysiak emphasized the significance of this achievement in enhancing transmission capacity within backbone networks, potentially translating into vastly improved connections for end-users.

"This groundbreaking accomplishment highlights the crucial role of advancing optical fibre technology in revolutionising communication networks for faster and more reliable data transmission. Growing system capacity by using more of the available spectrum - not just the conventional C-band but also other bands such as the L, S and now E-bands can help to keep the cost of providing this bandwidth down," Forysiak said in a statement.

"It is also a 'greener solution' than deploying more, newer fibres and cables since it makes greater use of the existing deployed fibre network, increasing its capacity to carry data and prolonging its useful life & commercial value. "

The findings of the team were published by the Institute of Engineering and Technology and presented as a post-deadline paper at the European Conference on Optical Communication (ECOC).
