NTT and Partners Show 1 Petabit/Sec Transfer Over 50km of Fiber
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.
That's a lot of porn.
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 !!
Muchas Gracias, Señor Edward Snowden !
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.
It's a small world and it smells funny; I'd buy another if it wasn't for the money; Take back what I paid (SoM)
x shows a successful transmission of y bits per second over a z-core optical fiber w km long.
Is that good? Is that much faster than before, or only a bit?
systemd is Roko's Basilisk.
That's some really fast porn.
The future is now. Soon every American home will integrate their television, phone, and computer. You'll be able to visit the Louvre on one channel, and watch female mud wrestling on another. You can do your shopping at home, or play Mortal Kombat with a friend in Vietnam. There's no end to the possibilities.
I think Slashdot has to get it right. We use LOC (Library of Congress) as the analogy for this story because it deals with transfer speed. For anything else, we use a car analogy and it always isn't the same car.
I propose a change. We need to standardize. Therefore, we should use the number of mini-vans (each filled with books) that can be parked in the LOC. I only suggest we use a mini-van since it has more storage space. This is challenging in itself to standardize since mini-vans must be parked so we will lose out on floor-to-ceiling space vs traditional bookcase technologies currently used.
Now my boss is going to want me to implement it commercially.
Of course data is such a precious and finite resource. Sure, we can use it so much faster, who cares if we'll run out? Oh wait... wrong metric. Okay, so we all know that data caps are BS, and that ISPs whinge about overusage, hence the caps. When they bring things like Gigabit Ethernet and now this, rendering the 'oh, we don't have the bandwidth so we have to limit it' argument invalid (especially with the known presence of dark fiber buildouts) why hasn't some agency or coalition come together to force data providers to stop treating data as a need-to-meter-amount resource like water or natural gas and start treating it like the need-to-regulate-speed resource like highways? It makes much more sense to limit someone based on how fast they can download data, not how much they can fill an imaginary bucket. If they're so worried about bandwidth, they need to start offering more realistic packages for light, medium and heavy users or something. Say about 1.5MB for light or email only users, 5MB or so for medium users and gamers, and 15MB for high users, and the just go up from there for ultra heavy users or biz class users who need those kinds of packages. I guarantee there will be people who will be perfectly happy paying $100 a month for 25MB throttle if they can use it as much as they want guaranteed, especially if they can drop down to a $30 5MB tier with the same unlimited usage. One person can get along fine with 5MB for watching HD Netflix and Youtube, and most users are just single users. Plus, if they really want, it's trivial to even offer you a bandwidth speed customized to what you need if they reallly wanted to. As long as they stopped treating it like we were going to have to mine for the last bits of useable data out of some hole in Zimbabwe for $10,000 a kilobyte or something.
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.

Depends how much .jpg compression you use...
At that rate it can just keep up with the amount of data produced by CERN when it is in operation. http://www.v3.co.uk/v3-uk/news/2081263/cern-experiments-generating-petabyte
