back to article Deutsche Telekom shatters data-transfer speed record

Researchers at Deutsche Telekom's T-Labs have blasted bits at impressive velocity down a single optical fiber, breaking the previous long-distance data-transfer record by more than a factor of two. The bit boffins achieved a 512 gigabits-per-second transmission rate over a single optical fiber from Berlin to Hanover and back, …

    77 music CDs in one second

    The sound you hear is the RIAA and the BPI expiring from apoplexy!

      It's only an equivalent rate; the experiment got cancelled after the first three CDs when automated "Three Strikes" software disconnected them.

        We don't have three strikes here in Germany and many ISPs roundly ignore requests to associate IP addresses of alleged P2P users with customer details.

    El Reg units?

    Surely we need this new uber-capacity pr0n hose specified in terms of the standard unit of the kilowrist?

      could be based on the size of a standard resolution 30 second preview clip; usually one of four so maybe a semi-demi-spank?

      If you need something doing...based on the figures here:

      The demo link was thus able to deliver 'pleasingly sharp' gratification at an impressive 15.6killowrist, and the proposed switch was just a few tissues short of the mythical Megawrist barrier that has eluded desperate boffins so far.

    Of course...

    Deutsche Telekom is also one of the providers which complains about their customers using the Internet to much.

    I mean think of it. 512 GBits per wavelength per fiber! That's a lot, particularly since Deutsche Telekom is not exactly a company known for having the smartest beans in the pot, and you'd expect that technology to be available in commercial products, soon.

    (Ignore the text and just look at the acting, here they are determining phone numbers, the rest of the story is how their boss complains about 2 customers getting assigned the same number)

    so home users

    could use their monthly cap in 20 seconds!

      Wow I want the monthly cap your on. My 10GB cap would be gone in 0.2 seconds.

      My German ISP has no monthly cap. My router tells me I shifted 116GB last month.

        Re: so home users

        One should note that the earliest tariffs for DSL in Germany by Deutsche Telekom were based on time. That's why Germany has PPPoE and "dial in", they even continued the same user names from their old "Prestel"-based BTX and the automatic hangup after 24 hours.

        Re: so home users

        Same here. No cap on Deutsche Telekom.

        Back when I was a tester for SUSE Linux, I would mampf my way through 3-400GB a month with ease. DT never batted an eyelid.

        We looked at Fibre, here at work, last year. Telekom wanted around 2K€ a month for 10MB symetrical. I hate to think how expensive that link would be!

    Can't wait...

    ... until this technology is rolled out to the fibre BT are installed to my house which is scheduled at some point Q2 in the year 2406.

    77 music CD's... I'm surprised the Reg hasn't got its own standardised unit for this.

    Optical tunnelling?

    "We are very proud of having attained this tremendous transmission performance *over the Internet* under real-world conditions" (my emphasis)

    So are they tunnelling photons inside IP packets and sending them over the commodity Internet? Or is there just a shortage of clue in the PR department?

    Wrong big G string

    Typical telco exaggeration as in( Subtracting out the error-correction overhead, the total usable bandwidth was 400Gb/s ) we should all note that Gb/s is the abbreviation GigaBYTES per second and bits is done with a small g. Typical telcos trying to slip in a factor of 8 times more than reality just like with the ATT 4G Lite which is really 3G. We did a spoof of this stuff called MEGA BS in Telcoland =
