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 answer is "we don't need to." The very first sentence in TFQuote says "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."

  • Not at my ISP. Damn, that's fast.
    • Well, it makes sense for the "Undersea Cables" to go this fast... where else does anybody have enough data to fill that bandwidth?

      • Porn!
        • I'm not even sure about that. Assuming you take the comparison of 50 full to the brim HD Blu-ray discs per second, that's over 4 million such discs per day. I'm not certainly exactly how many pornographic films have been created over the years, but I don't think it's quite up to that. IMDB has (as of Dec. 2019) just a bit under 540,000 movies (or about 4.5 million T.V. episodes) in its database [imdb.com]. Maybe if you burned all of the digital content that's released to the internet to disc you'd start to approach or

            Well then, clearly we need to increase production. We're on a war footing, aren't we? Where are our Riveting Rosies?

      • Large ISPs for their long haul backbone networks. This isn't something you'd use for residential customer edge connections.
        • Probably right, but I remember 9600 baud being insanely fast. Too fast to even read the text as it scrolled by. That was less than 40 years ago. Now I'm musing over upgrading my home network from 1G to 10G.

        • Eventually the technology will move downmarket and it _will_ be residential; and that's a good thing. I think one of the Cringelys used a pringles antenna to connect down valley to a user who had a high speed connection who was willing to sell a bit. Got around some cali-cul-de-sac with shit internet. This kind of technology should not be locked up by some Wells Fargo of ISPs.
      • If it is cheap enough it might not be about providing the huge increases in bandwidth and more about having to rollout less fibre cables.

  • you better hope they just write it off as an error or you will owe them billions in overage charges. /s

      What's the volumetric conversion between those 100GB Blu-rays and 512GB microSD cards? Would I save enough space in the station wagon to bring along a dog?

  • 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.

    • by _merlin ( 160982 )

      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.

      A lot of them ... when set up as a RAID.

    • by guruevi ( 827432 )

      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.

      • by guruevi ( 827432 )

        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.

  • Why does everything always have to be in the frame of "the internet"? Why not just refer to "fiber optic cable bandwidth" or something more accurate?
    • Because that's better then calling it "cloud speed"? :-)

      But yes, I immediately had the same reaction.I suppose that is for the masses to associate it with Skype, Instagram and the rest of it?

  • The problem here is this isn't an Internet record, because there was no Internet anywhere. Where are the routers or switches? And what is the deal with calling it a "speed" record when they didn't measure the speed of anything, but rather some form of capacity?

  • 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

    • Couple thoughts.

      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 $$$.

  • Now any signal sent over any medium is "internet"?
    • Now any signal sent over any medium is "internet"?

      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.

  • I wonder when I can buy an internet package with such bandwidth

You know you've landed gear-up when it takes full power to taxi.
