back to article Boffins shatter data transmission speed record

European scientists claim to have achieved a data transmission speed of 1.8 petabits per second, all with a single laser and an optical chip.  For those unsure, 1.8Pbit/s is a lot. As in, more than the total volume of global internet traffic sent every second, the Technical University of Denmark (DTU) said in a statement. The …

        What about the colors on the wires? White Blue, Blue, White Orange, Brown, White Green etc... surely they must carry the correct colors???

      The Wikipedia has it like this:

      "The Technical University of Denmark (Danish: Danmarks Tekniske Universitet), often simply referred to as DTU, is a polytechnic university and school of engineering. It was founded in 1829 at the initiative of Hans Christian Ørsted as Denmark's first polytechnic, and it is today ranked among Europe's leading engineering institutions."

      "From 1933, the institution was officially known as Danmarks tekniske Højskole (DtH), which commonly was translated into English, as the 'Technical University of Denmark'."

    Neat, how small is it?

    Because it would be interesting to see if this will be an obvious add to the silicon photonics stuff that Intel has been too busy putting out fab yield issue fires to do much interesting stuff with recently.

    Sounds like a way to get a large boost to on-box optical SerDes as well if both can be fabbed at the same time. Good to know there may be something interesting to look forward to in a decade or so. (Just like 3d stacked chip fab teasers in years gone by).

    nearly enough capacity for the interwebs to carry all the POS insecure IOT, spammers, snoops and of course, javascript. Browsers will be unable to be used for information as all the snoopware code, logging, monitoring, malvertising, advertising code runs and reports. A few pointless, rehashed, badly acted, sermonising repeats of some 60 year old cartoon or movie will add to the toxic mess. Sort of makes me wish the snoopers demanding backdoors get their wish.

    Well, yes, indeed it is less than a third. Also less than a quarter and less than a fifth. *BUT* it's a bit more than a sixth. Wouldn't that be the better comparative?

    Okay, if 1.8Pbps is more than all Internet traffic today, and knowing that the natural effect of having more of something is that you use it up, what is an Internet with 100Pbps goint to look like ?

    Are we going to have petabytes of cat videos in VR ?

    "Oxenløwe said the system could also greatly reduce the energy footprint of the internet since just a single laser would be needed in place of "hundreds of thousands of the lasers located at internet hubs and datacenters"

    And create a massively significant single point of failure?

    Are boffins sort of like puffins who can solve tech things?

    I have to say these boffins are great. They’re always solving everything and coming up with excellent new solutions to things.

    Where do they live, what do they eat and what are their mating habits? David Attenborough could do a wonderful documentary.

    Honestly, just find it odd for a tech site to use headlines that belong in a British tabloid. It’s one stop short of calling engineers “a bunch of geeks.”

      I used to work as an engineer on scientific projects, and was proud to be granted the title of "boffin" by them sometimes. It was an acknowledgement of being part of the intellectual community as opposed to being a mere "technician".

      Seriously? You signed up as a commentard back in June 2010, and possibly were reading the site for a some while before then, and you STILL don't get the "house style"? And you managed to miss the many articles using the word "boffin" where someone else made the comments and had to have it explained to them?

    How much information is there? I mean, I know that the internet has led to the creation of a load of extra traffic which isn't actually true, but my Gb internets can deliver more stuff than I can consume.

      It will lead to the M25 effect for data (build a high capacity relief road and it doesn't relieve traffic as much as generate entirely new stuff).

    the transmission managed to hit 1.84Pbps over 7.9km (4.9 miles) of fiber line

    More than sufficient for datacenter application; just because its fibre doesn't mean it has to be able to go large distances.

    Only thing missing is details on the type of fibre line being used and its connectors.

    Looking at this story, it mentions a lot about transmitting this huge amount of data. Maybe the next thing they should work on is a receiver for it.

        As one with a name instead of a worthless AC using "AC" to post stupid nonsense: How dumb can you be to believe that there would be no receiver? "Transmit" means send AND receive. Therefore I down voted you.
