Researchers Manage To Transmit Data 4.5 Million Times Faster Than Average Broadband!

In today’s digitized world, the internet has become a crucial part of our personal and professional lives. From personal entertainment to corporate webinars, from free Wi-Fi in public areas to running government services and essential utilities, our lives are connected by the internet.

Additionally, our homes, workspaces and even industrial houses are being revolutionized by IoT (Internet of Things), artificial intelligence (AI) and similar technology.

It’s no surprise that we’re on the constant lookout for faster internet speeds, connectivity and data transfer capabilities.

In this regard, researchers from the National Institute of Information and Communications Technology (NICT) in Japan, Nokia Bell Labs in USA and a team from the Aston University collaborated to attain faster data transfer speeds and have some exciting news.

So, what did the researchers reveal? Let’s explore!
 

What Did The Researchers Announce?

 

• In a news article published on Aston University’s website, researchers from the university were able to send data at speeds 4.5 million times faster than the average home broadband speed.

• This was done by opening up specific new wavelength bands that haven’t been used in fiber optic systems.

• The research, which comes as a part of an international collaboration, saw the researchers transfer data at 301 terabits or 301,000,000 megabits per second by using a single, standard optical fiber.

• The team from the Aston Institute of Photonic Technologies was led by Professor Wladek Forysiak and Dr. Ian Phillips.

• Fiber optics are used by computers to transmit data by sending light signals across small and thin tubular strands of glass or plastic, which is also called the core. Typically, transmissions use light wavelengths of 850, 1300 and 1550 nanometers to carry data, however, the researchers used wavelengths not previously used.

• While the most used wavelengths include the conventional band (C-band) and the long-wavelength band (L-band), the researchers opted to use additional spectral bands, which were the extended wavelength band (E-band) and the short wavelength band (S-band).

• This was done by developing new devices called optical amplifiers and optical gain equalizers, which was led by Dr. Phillips.

• The speed comparison of home broadband mentioned in the research was sourced from Ofcom’s UK Home Broadband Performance Report, which was published in September 2023 and mentions the average download speed at 69.4 Megabit per second in March 2023, with a 17% increase year-on-year 

• The speeds observed here aren’t the fastest transmission ever achieved, as NICT (Japan) researchers hit speeds of 1.02 petabits per second or 1,020,000,000 megabits per second. However, in that experiment, they used a customized cable of four cores rather than a standard single-core line.

 

What Did The Researchers Say?

 

• Dr. Ian Phillips, School of Computer Science and Digital Technologies, Teaching Fellow, Electronics & Computer Engineering, said, “Broadly speaking, data was sent via an optical fibre like a home or office internet connection.

• “However, alongside the commercially available C and L-bands, we used two additional spectral bands called E-band and S-band. Such bands traditionally haven’t been required because the C- and L-bands could deliver the required capacity to meet consumer needs.

• “Over the last few years Aston University has been developing optical amplifiers that operate in the E-band, which sits adjacent to the C-band in the electromagnetic spectrum but is about three times wider. Before the development of our device, no one had been able to properly emulate the E-band channels in a controlled way.”

• Professor Wladek Forysiak, Aston Institute of Photonic Technologies (AiPT), College of Engineering and Physical Sciences, said, “By increasing transmission capacity in the backbone network, our experiment could lead to 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.”

• “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.”

As demand for faster speeds and more data increases, the belief is that new technology will be developed to meet the growing demand.

Do you think this breakthrough constitutes such development and will it gather the interest of technology companies looking to offer better internet connectivity for commercial, public and personal use?
