In the past few decades , the internet has changed most aspects of our lives and the technology is continuing to evolve. What if the entire content available on your streaming service could be downloaded in only one second? Yeah, London researchers have achieved the fastest internet ever by hitting a speed of 178 Tbps (terabits per second), or 178,000 Gbps.
The UK researchers from University College London (UCL) achieved a data transfer rate of 178 terabits a second which is five times faster than the previous record set by a research team in Japan, and approximately twice as fast as the fastest internet accessible today.
“While current state-of-the-art cloud data-centre interconnections are capable of transporting up to 35 terabits a second, we are working with new technologies that utilise more efficiently the existing infrastructure,” said lead author Lidia Galdino, a Lecturer at UCL and a Royal Academy of Engineering Research Fellow.
To achieve the lightning-fast speed, London-based researchers typically sent data over far wider wavelengths compared to the one used in optical fibres. Instead of 9THz which is still available in select few markets, the team used 16.8 Terahertz (THz). The one our internet runs on uses a 4.5THz bandwidth.
To do this, researchers combined various amplifier technologies needed to improve the signal power over this wider bandwidth and maximized speed by creating new constellations of geometric shaping (GS) that control the properties of each individual wavelength.
The advantage of the technique is that it can be cost-effectively implemented on existing infrastructure by upgrading the amplifiers located at 40-100 km intervals on optical fiber routes, the researchers said.
Naturally, with a global pandemic pushing many of us to work and socialize online rather than face-to – face, the need for faster speeds and greater connectivity has never been more topical – particularly with some 40 percent of the world ‘s population still to be linked.
