NTT and Partners Show 1 Petabit/Sec Transfer Over 50km of Fiber

Posted by timothy on Saturday September 22, 2012 @10:33PM from the wake-me-up-when-it's-petabytes-instead dept.

symbolset writes "NTT and some partners, in a late paper to the ECOC 2012, show a successful transmission of 1 petabit per second data transfer over a 12-core optical fiber 52.4 km long." How long that transfer speed would take to transfer one Library of Congress's worth of data all depends on who you ask.

  You could use up your monthly bit-cap in about five seconds... USA! USA! USA!
  I dunno, I'd be pretty happy with a 655360 gigabyte bit-cap if it'd take 5 whole seconds to chew it up at this speed.

  OMG. You would need a script to generate all the zero's needed for the amount of damages the music companies would sue for if you used that just for downloading music.

NSA data gathering capability by Taco+Cowboy · 2012-09-22 22:41 · Score: 5, Insightful

I read TFA, click on one of the links, and ...
http://www.popsci.com/technology/article/2011-05/every-six-hours-nsa-gathers-much-data-stored-entire-library-congress
Every day NSA gathers 4 times the amount of data of the entire library of congress
I do not question the availability of the disk space for all those data - after all, NSA has an unlimited budget on purchasing hard disks.
But ...
How are they going to crunch all those data?
How big the machine they have to crunch at least 40 petabytes of data every-single day?
And we are not talking about simple crunching - they need to sieve through all those data to find things that are worth to keep - and then, many of those things that are worth to keep may themselves be encrypted (terrorists ain't stupid these days) - and it takes a helluva juice to decrypt all those encrypted data.
It's truly mind boggling !!

  Just look at commercial institutions that do the same thing. Google, for example.

  Some would argue that not wanting to be "average" is being average.
LoC per second is just bandwidth by jd · 2012-09-22 23:14 · Score: 4, Funny

To be a true measure, you need latency as well. After all, you can't really play a decent MMORG if the latency is through the roof.
As two dimensional values confuse people, I suggest dividing the bandwidth by the delays in getting it, giving you Libraries of Congress per second per fillibuster.

If you created a fiber loop around a drum, using 50 km of fiber and this technology, you would be able to use it as ultra-high-speed storage
It would store 20.8 Gbytes of information with read-write speeds of 1 Pbit per second, and a random access r/w time of 166 microseconds max.
Not bad eh? But unlikely to come in 2.5" format I suspect.
