Japanese scientists transferring data at 14 Tb/s

Posted on 01.10.2006 at 12:07 in Tech News by Martin

Crazy high-speed news appeared on the website of japanese ISP called NTT. Nippon Telegraph and Telephone has announced data transmission at a rate of 14 terabits per second over a single optical fiber. The value of 14 Tbps (111 Gbps x 140 channels) greatly exceeds the current record of about 10 Tbps and so claims the record of the world’s largest transmission capacity. They had to use a lot of special technologies like wavelenght multiplexing or ultra-wide amplifiers to achieve such a speed. You can read more details about this record at their website if you are interested in technical stuff. I’ll probably consider moving to Japan, this is totally worth it :) .

    14336/8 = 1792.

    1792MB/s hmm very tasty speed.

    pleb: Maybe, your calculator is wrong because it is 1792 GiB/s! ;)

    No I don’t think I’m wrong mate.

    Let’s see 14 Terabits = 14 * 1000 Gigabits = 14,000Gigabits. Divide by 8 gives you bytes and therefore you end up with 1792MB/s (megabytes per second)

    Hmm yeah it’s confusing but I think he’s correct as connection speeds are listed in bits > terabits. gigabits and megabits, you have to divide by 8 to get bytes.

    If you look the quoted connection speed its rated as Tbps and it’s the lower case b that means bits if it was TBps then uppercase means bytes.

    but the site claims
    “140 digital high-definition movies transmitted in one second”

    either they have their math wrong, too, or they are talking about very very very short HD movies…

    “Nippon Telegraph and Telephone Corporation (NTT, Chiyoda Ward, Tokyo, President and CEO is Norio Wada) has successfully demonstrated the ultra-large capacity optical transmission of 14 Tera bits per second (Tera is one trillion) over a single 160 km long optical fiber. The value of 14 Tbps (111 Gbps x 140 ch) greatly exceeds the current record of about 10 Tbps and so claims the record of the world’s largest transmission capacity”

    it’s really 1629 GB/s
    fuck. =)

    I’m really going to need a lot of dvd’s with that speed… :P
    2gb/s is alright for me, I offer you the other 1790gb, don’t need them!

  11. yeah

    You divided GIGAbits by 8 to get MEGAbytes?

    I think we’re unlikely to see pleb post anymore.

    1792 GB gb gb gb gb gb gb gb gb.
    Not MB…

    The End.

    14/8=1,75TB/s
    1,75*1024=1792GB/s
    ..Enough proof for you? :)

    Funny enough, 1792gb/s is way faster than my HD could write the data, not to mention, it’ll be filled to the last byte within half a second (or less ;P).

    What’s the fuzz? The bottleneck is…
    Need no say more!
    By the time the rest of the world is to profit from such a speed, we are all old and incapicitated, the next generations will profit by it and then they’ll say:”Hey man, damn slow speed, 1792Gb….”
    So, be happy with your dsl….. and stop naggin’ numbers.
