Default revolutionary breakthrough on data transmission

It's an science article behind a paywall only a part of it is there to read.

Quote:
We experimentally demonstrate transmission of 1.84 Pbit s–1 over a 37-core, 7.9-km-long fibre using 223 wavelength channels derived from a single microcomb ring resonator producing a stabilized dark-pulse Kerr frequency comb.

Here is a translation from a Danish Science article which explain it more simple.

Danish Videnskab writes:

Record: Danish-Swedish chip can transfer twice the total Internet traffic data every second

Researchers from the Technical University of Denmark and Chalmers tekniska högskola in Gothenburg have managed to transfer more than 1.8 petabits per second using a laser and a single optical chip.

That's the equivalent of 1.8 million gigabits, or twice the world's total internet traffic.

The study, published in the journal Nature Photonics, shows that the experiment succeeded using a special optical chip that can use the light of a laser to create data signals.

This is a new world record, writes DTU in a press release.

The new invention, which uses only a single laser, can transmit data that would otherwise require more than 1,000 lasers with today's very best equipment. It could therefore prove to be a revolutionary discovery.

However, the researchers actually came across it by chance. In fact, the chip wasn't optimised at all for what the experiment entailed, but the researchers have managed to work out why

The invention consists of an optical chip that receives infrared light from a laser. The chip is able to multiply the frequency of the light by hundreds of times. That means hundreds of different colours.

The chip can then produce a beam of light with the many different colours in it. It can be seen a bit like a comb, where each tooth in the comb is a distinctive light. All the colours are locked at a certain distance from each other.

The researchers then managed to turn each colour in the light into a data signal, which it is then possible to reassemble into a single light. It is then possible to transfer the light as data to a light guide that can receive and read data from it.

The researchers have also worked out that there is considerable potential for scaling up the project. According to them, a single laser would be able to transmit up to 100 petabits per second.

So the experiment probably also bodes well for the future power consumption of the internet. This is explained by one of the researchers behind the project, Leif Katsuo Oxenløwe, professor and head of the basic research centre Silicon Photonics for Optical Communications at DTU.

"In other words, our solution has the potential to replace hundreds of thousands of lasers in Internet nodes and data centres, all of which consume power and generate heat," says Leif Katsuo Oxenløwe in the press release.

Thats fast. Or is a lot. Not sure what description matches the fact better: speed or quantity.

I forgot all about this thread.

Yes it's fast and it's a lot.

What I'm speculating in is this:

You have a computer based on lights-Laser. What does it help that you could send the entire contains on the internet during a second or two, if the fiber isn't geared for this. Our fiber cable who I use has a limit of 1000-something Mbps if I remember correctly.

Special made fiber cable can carry 5000 Mbps information

Perhaps some technicians, scientist or similar have invented some type of fiber who can carry 10-100 Tbps

Maybe it'll be ready for rollout in 70 or so years, even then, every part of a PC and all the infrastructure will have to be upgraded to handle those speeds, it's all piss and wind in the minds of a few scientists old boy, consensus says it won't happen as it'll be too costly.

So, the question here is: when do we get the transporters?
