Germans transfer data at 26Tb/s

2011-05-23 22:18

Berlin - Computer users who despair over slow internet connections should take heart. German scientists have broken a speed record, sending data contained on 700 DVDs over a single laser beam, in one second.

The scientists at the Karlsruhe Institute of Technology (KIT) on Monday said they had broken the world record by sending data at a speed of 26 terabits per second.

The data, sent over 50km on a single laser beam, was coded thanks to a system known as orthogonal frequency-division multiplexing (OFDM) in which the laser beam is divided into separate colour streams.

"With 26 terabits per second, you can simultaneously transmit up to 400 million telephone calls per second," said Professor Juerg Leuthold of the institute in a statement.

    Nice!

  • JM - 2011-05-23 22:45

    Please SA, get onto this with all your might! 700 DVDs per second, WOW, I want!

      It's a German invention. It'll stay in Europe for a few years, then the Americans will find it relevant to their interests, and about 50 years from now we'll have 50Mbps lines. A friend of mine in Sweden has a 100Mbps down and 90Mbps up line. Costs him about R400-R500 a month, uncapped.

    I gonna apply by Telkom tomorrow for this speed. HE HE HE

      In all our dreams

  • birdman - 2011-05-23 23:34

    It's like getting the answer before you can think of the question!

  • Louis - 2011-05-23 23:36

    I'm also gonna place an order for this , one day when i'm 200 years old it will most prob be in SA. Telkom must first get rid of 384 kb Adsl and make 512 entry level

      rammstein.f4n - 2011-05-24 07:53

      I'd say 1Mbps should be entry level. And ridiculously cheap.

    As I read this I am waiting for my Ubuntu install CD download. 5 hours, 24 minutes remaining...

      In South Africa, snail mail is sometimes quicker... or you could use a pigeon, this was proven to be faster in a experiment a little while ago...

  • SoulF - 2011-05-23 23:53

    This would eat all my available HDD capacity in a couple of milliseconds lol.

  • mike.james.warren - 2011-05-24 00:14

    Hmm bit scary having laser beams flying all over the place.. Oh and Telkom claims 000000.3762 terabits/s (384 kilobits/s) a second is "world class broadband".

      White Wolf - 2011-05-24 02:08

      You do know that 000000.3762 terabits/s is exactly the same as 0.3762 :p Think your decimal point should have been 5 places to the right.

      elbie - 2011-05-24 05:57

      Left, White Wolf?

      Swazy - 2011-05-24 09:18

      LOL buddy, looks like math isn't ure strong point. Maybe telkom have a position for you?

      Sammajoor - 2011-06-23 17:38

      these lasers run through fibre, not through the air

  • Martin du Plessis - 2011-05-24 00:20

    And the sound you heard moments after this story broke was that of thousands of RIAA and MPAA agents all screaming out in terror and pain, and then were suddenly silenced.

  • SlayerSaves - 2011-05-24 00:25

    Think of all the prons! Naked News will be the absolute least of the moral watchdogs' problems!

      daaivark - 2011-05-24 08:13

      What's a "pron"?

      cromagnon - 2011-05-24 08:35

      pr0n is how you spell porn 'l33t', a type of spelling format made famous by hackers.

  • 24.comreader - 2011-05-24 00:35

    and I complain about our 1.2 gigabyte internet backbone link at the office and 100 megabyte link at home (Switzerland) :(

      rowan.swanepoel - 2011-05-24 09:04

      you sure its not gigabit and megabit?

      PlayOn - 2011-06-23 18:23

      I find amazing and worrying how interchangeably people use the terms megabit and megabyte or for that matter gigabit and gigabyte. There is, after a factor 8 difference between these (8 bits in byte!).

  • Lekker Jan - 2011-05-24 04:07

    Lol, here in Hong Kong, I pay around R200/month for unlimited 100mb connection. I cannot imagine 384kb.

      Looter - 2011-05-24 04:35

      honestly i dont know what you guys do with such speed, unless it is to watch movies all day??? I have a 4mb line and that plenty, all i could ask for and im a serious gamer! Ping of 15 to 50ms is perfect, and i can download youtube vids without waiting, not HD but why always over the top...its over the top that got us in our mess we are today, how the air?

      NuttyZA - 2011-05-24 06:41

      Looter... and Bill Gates once said "I can't see anyone needing more than 64kb of RAM"... I have a 4mb shaped connection (so it's closer to 1mb/sec) and it sucks... at 100mb/sec, you could download an entire movie (avi) in 7 secs.... TV really will start becoming a thing of the past

      ZipZap - 2011-05-24 07:23

      bastard.

      Johan van Zyl - 2011-05-24 08:56

      @NuttyZA - Not 7 secs. Absolute minimum of 56 seconds for a 700mb avi file under perfect latency conditions, and if the source of download can allocate that size pipe (thus 56 seconds in theory). Remember, it is megabits, not megabytes.

      NuttyZA - 2011-05-24 10:22

      @Johan... true but 56 Seconds is still a sh!rt load better than we currently get... and if you're streaming, the movies downloaded before the opening credits have even started

      Martin du Plessis - 2011-05-24 11:35

      I hate you all. My top Dl speed hovers around 45Kbps

  • Arri - 2011-05-24 04:29

    Imagine Telkom had an advert running for that..

  • FearoPhobia - 2011-05-24 05:35

    Cool now I can use up my 5Gb a month limit.... in 0.0005 seconds!

  • Casper - 2011-05-24 06:03

    How's that for swooooossshhh!

  • Sammy - 2011-05-24 06:31

    Very cool but we will NEVER see this sort of tech in ZA, Imagine how much ICASA would kick against something like this?

  • kaMazibuko - 2011-05-24 06:33

      ZipZap - 2011-05-24 07:27

      a:\ UPGRADE. MFM hard drives are supposed to be clocks at this point as well!

      John - 2011-05-24 07:35

      Stiffy or the famous A drive, i thought they were all mesuem pieces by now? Damn Winentendo users!

      or gotten someone to shout the code at you in binary through the phone.

  • noitall - 2011-05-24 06:41

    400 million telephone calls a second - thats good for my wife what's the rest of you going to do?

  • ZipZap - 2011-05-24 07:08

    awesome, so in about 20 years we will get that at quadruple the price.

  • Jason Francke - 2011-05-24 07:14

    If only telkom can Stop trying to use old technology and stop trying to take all our money and actually do this country right and then we as South Africa can actually be transfering that kind of DATA...

      ZipZap - 2011-05-24 07:30

      state enterprise... not going to happen. look at everything run by the state-rapists of wallets.

      Jason Francke - 2011-05-24 07:37

      If ICASA gets telkom to do what they did in the U.K. We can get cheaper and faster Internet. They call it Local Loop Unbundeling(LLU).Last I hear MBeki went to Europe and saw what they were doing. He was busy lobbying for it then he lost his job the whole thing went hush, hush after that.

  • Karoogypsy - 2011-05-24 07:18

    WOW will take up to 10 days in South Africa. Reading this we realise how 3rd world we still is !

      Uwe Klopfer - 2011-05-24 09:15

      we is yes, we is....

  • Willie - 2011-05-24 07:32

    OH I wish i can get 384kb/s I tried to download a driver for my wifes laptop over 3G it started at 49kb/s and i killed it when it got to 2kb/s I cannot even imagine how fast this will be, where we are there is no ADSL, hellkom want to charge me some redicilous amount to install it and we went for 3G. I got the message your download of 20mb will complete in 1 day and 17 hours.

  • thabatao - 2011-05-24 07:34

    The world's internet will get this in 2015 and South Africa in 3010. We will have to wait a 1000 years before Telkom will implement it.

  • daaivark - 2011-05-24 08:11

    The way my machine works it's definitely not here yet.

  • Horst - 2011-05-24 08:13

    I see everyone (nearly) is moaning about Telkom. Do they have the monopoly on internet connectivity? If yes, isn't it time to change that?

  • preshengovender69 - 2011-05-24 08:22

    that will be tons of porno

  • Esperanza - 2011-05-24 08:27

    Now that's what I call sexy. Wow.

  • Dean - 2011-05-24 09:01

    You could download the entire Internet in about 3 minutes. How cool is that. Just find a HDD that is 500 gazillion Terra-bytes in size.

      Sum1 - 2011-05-24 09:27

      Yeah... and Linux. "wget http://*.*" :-)
