Researchers Claim New Internet Speed Record of 44.2 Tbps (theverge.com) 47
Researchers based out of Australia's Monash, Swinburne, and RMIT universities say they've set a new internet speed record of 44.2 Tbps, according to a paper published in the open-access journal Nature Communications. That's theoretically enough speed to download the contents of more than 50 100GB Ultra HD Blu-ray discs in a single second. The Verge reports: What's interesting about the research is that it was achieved over 75km of standard optical fiber using a single integrated chip source, meaning it has the potential to one day benefit existing fiber infrastructure. The test fiber connection ran between RMIT's Melbourne City campus and Monash University's Clayton campus, and the researchers say it mirrors infrastructure used by Australia's National Broadband Network (NBN). The findings represent a "world-record for bandwidth," according to Swinburne University Professor David Moss, one of the team members responsible.
Those speeds were achieved, thanks to a piece of technology called a micro-comb, which offers a more efficient and compact way to transmit data. This micro-comb was placed within the cable's fibers in what the researchers say is the first time the technology has been used in a field trial. Now, the researchers say the challenge is to turn the technology into something that can be used with existing infrastructure. "Long-term, we hope to create integrated photonic chips that could enable this sort of data rate to be achieved across existing optical fiber links with minimal cost," RMIT's Professor Arnan Mitchell says.

The wrong NBN problem (Score:2)
The problem with the NBN has never been the back end infrastructure. I appreciate that the rest of the world will gain from this technological development, but in researching improvements to NBN maybe they should try and figure out how to increase speeds over a corroded copper twisted pair which connects houses to the fiber.
Re: (Score:3)
In Sydney and Melbourne the NBN does get congested in the evenings. But the biggest issue is access costs charged to the ISPs that are then passed on to the customers. NBN is expensive.

That's only 5GB per second, the fastest PCIe SSD is capable of reading at 5GBps and writing at 4.4GBps. So a small array (2 or 4) of those can definitely sustain it.

Miscalculated. It's 5000 GBps. So you only need 1000 SSD's like that. I've seen 4000 disk configurations over InfiniBand in compute clusters so it's not unreasonable.

The road to more AI surveillance (Score:2)
With the Internet being fast enough for us to watch video over it does one have to wonder what to do with higher speeds. The answer will likely be: more surveillance with artificial intelligence. While most people may only be interested in watching one video stream at a time and thus find satisfaction at speeds around 100 Mbps per person can IAs surveil many more streams, coming from countless cameras. So the most interesting question is at what speeds will global surveillance find its satisfaction? The ans

First, the Internet is only marginally fast enough to do as much video as people want to do. With the surge in demand from Coronavirus, major providers downgraded their default streaming quality to reduce the load.
Second, it takes a lot of infrastructure for distributed hosting to get all this to everybody. The faster the backbones, the more you can consolidate data centers to save $$$.

Yes, indeed. The Internet can run through air on sound waves, EM waves and photons, as well as through optic fibres, copper & aluminium wires (any conductor really), twisted, untwisted, shielded or unshielded, ... any medium one can think of really. Over distances from less than a meter to distances as far as Mars and beyond. It can get carried, packed or encapsulated on top of many protocols, too. But this wasn't just any signal over any medium. You should read the article.
