Scientists in the United Kingdom have claimed that they have achieved the world’s fastest internet data transmission rate, and as per their estimates, it is a speed which would make it possible to download the entire Netflix library in less than a second.
The researchers from University College London (UCL) in the UK have achieved a data transmission rate of 178 terabits a second – which is five times faster than the previous record. The record, which is described in a research paper and is published in the journal IEEE Photonics Technology Letters, is double the capacity of any system which is currently deployed in the world.
This speed can be achieved by transmitting data through a much wider range of colours of light as well as wavelengths and it is typically used in optical fibre, the researchers said. What they did was essentially combine different amplifier technologies which needed to boost the signal power over this wider bandwidth and then this maximised speed by developing new Geometric Shaping (GS) constellations. It can also manipulate the properties of each individual wavelength.
These GS constellations are patterns of signal combinations that make best use of the phase, brightness as well as polarisation properties of the light.
Now, the benefit of this technique is that it can be deployed on already existing infrastructure cost-effectively hence, by upgrading the amplifiers which are located on optical fibre routes at 40-100km intervals as per the researchers.
“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.
