Scientists at University College London have achieved a data transmission rate of 178 terabits per second (tbps) – a speed at which you could download the entire Netflix library in less than a second.

The breakthrough involved a collaboration between University College London (UCL) and two companies, Xtera and KDDI Research. The technology used a much wider range of colours of light, or wavelengths, than is typically found in optical fibre. Most of today’s infrastructure has a limited spectrum bandwidth of 4.5THz, with 9THz commercial systems entering the market. The researchers in this study, however, used a bandwidth of 16.8THz.

The hyperfast speed – around three million times faster than conventional broadband – was made possible by combining different “amplifier” technologies to boost signals over this wider bandwidth, and then maximised by developing new Geometric Shaping (GS) constellations. The latter are signal combinations that make best use of the phase, brightness and polarisation properties of light, manipulating the properties of each individual wavelength.

SpaceX just hit the FCC’s goal for low internet lag. Next step: 1 gigabit internet speeds.

Researchers have fashioned ultrathin silicon nanoantennas that trap and redirect light, for applications in quantum computing, LIDAR and even the detection of viruses.

Light is notoriously fast. Its speed is crucial for rapid information exchange, but as light zips through materials, its chances of interacting and exciting atoms and molecules can become very small. If scientists can put the brakes on light particles, or photons, it would open the door to a host of new technology applications.

Now, in a paper published on August 17, 2020, in Nature Nanotechnology, Stanford scientists demonstrate a new approach to slow light significantly, much like an echo chamber holds onto sound, and to direct it at will. Researchers in the lab of Jennifer Dionne, associate professor of materials science and engineering at Stanford, structured ultrathin silicon chips into nanoscale bars to resonantly trap light and then release or redirect it later. These “high-quality-factor” or “high-Q” resonators could lead to novel ways of manipulating and using light, including new applications for quantum computing, virtual reality and augmented reality; light-based WiFi; and even the detection of viruses like SARS-CoV-2.

The internet has transformed most areas of our lives over the last few decades, and the technology keeps improving: researchers just set a new record for data transmission rates, logging an incredible speed of 178 terabits per second (Tbps).

That’s around a fifth faster than the previous record, set by a team of researchers in Japan, and roughly twice as fast as the best internet available today.

With 4K movies about 15GB in size, you could download about 1,500 of them in a single second at the new speed.

Engineers in London just smashed the world’s data transmission rate with a speed a fifth faster than the previous record. They hit a rate of 178 terabits a second, beating the previous 172 terabits.

The world’s fastest data transmission rate has been achieved by a team of University College London engineers who achieved internet transmission speed a fifth faster than the previous record.

Working with two companies, Xtera and KDDI Research, the research team led by Dr. Lidia Galdino (UCL Electronic & Electrical Engineering), achieved a data transmission rate of 178 terabits a second (178,000,000 megabits a second) – a speed at which it would be possible to download the entire Netflix library in less than a second.

The record, which is double the capacity of any system currently deployed in the world, was achieved by transmitting data through a much wider range of colors of light, or wavelengths, than is typically used in optical fiber. (Current infrastructure uses a limited spectrum bandwidth of 4.5THz, with 9THz commercial bandwidth systems entering the market, whereas the researchers used a bandwidth of 16.8THz.)

First and foremost, I would likd to reiterate that Elon Musk is not motivated by money. Elon Musk uses his wealth to make a difference to mankind. Yes he makes billions (and deservedly) but he invests his billions for other projects too. From Tesla to Neuralink; from Starlink to The Boring Company. And for me the ever exciting SpaceX. My only wish is I live long enough to witness his many inventions and projects.

Four months ago when I did the video below and predicted that Elon Musk would be the World’s First Trillionaire, most people laughed and ridiculed the video especially as at that time Elon was only the 35th Richest Man in the World with a net worth of around the $30 Billion mark.

“We’re essentially trying to trap light in a tiny box that still allows the light to come and go from many different directions,” said postdoctoral fellow Mark Lawrence, who is also lead author of the paper. “It’s easy to trap light in a box with many sides, but not so easy if the sides are transparent—as is the case with many Silicon-based applications.”
