Japanese demonstrate ultra-fast 1 petabit per second technology

Posted 24 September 2012 18:16 CET by Jan Willem Aldershoff

Researchers of Japanese telecom giant NTT have demonstrated an impressive data transfer technology. They were able to achieve a download speed of 1 petabit in a single second over a distance of 52.4 kilometers. Converted to gigabytes, that is a whopping 131,072 GB per second. The result is described as ‘a new world record throughput over a single strand of optical fiber’ and is an enormous increase over the previous 305 Tbps record. Downloading at this speed means that you could watch 5000 HDTV streams over a single fiber and the researchers claim that it’s 1000 times faster than current commercially available technology.

Researchers expect that over 10 years we will consume 10x more data than now due to the availability of faster connections, both wired and wireless. With current technology it’s hard to keep up with the demand, mainly due to the fact that when multiple fiber cores are close to each other, they suffer from data leakage due to electromagnetic interference.

To achieve the 1 petabit a second the researchers had to rethink how the cores in fibers are combined and found the solution by designing a special fiber that arranges 12 cores in a near cylindrical configuration, where there is only interference on the left and the right of the fiber.

They also changed how the optical sensors and transmitter works. Normally these work by putting the signal on and off, thus having two states. With the new technology they found a way of sending more values at once, this technology is called: ‘polarization multiplexed QAM digital coherent technology’.

The researchers expect that in the future they will be able to achieve the higher speeds over longer distances.

For this to be a truly reolutionary jump they will need to be able to do this on EXISTING cable.. nobody's gonna rip up old fiber and replace it with new fiber JUST to get a 1000x increase in speed. They'll have to do better with existing cable first.. it's quite possible if they can get this technology ready for commercial use, all NEW builds might just end up using the newer cables if they aren't substantially more costly to make..

Doesn't matter. The ISPs will throttle us down to 500kbps anyway. LOL.

I think I just heard a collective groan from the headquarters of the RIAA and MPAA.

NTT needs to get these innovations out of the labs and into commerical production.. The biggest buyers of this cabling would be for international undersea cabling that could have the 1000 fold increase in throughput. As it is, international bandwidth is at a premium and is throttled among the major telecom companies.. imagine getting your full tier capacity to almost any country around the world?!? This cable could ensure that and more..

Also, internet-2 cabling could aggregate with fewer actual fibers-- 1 or 2 vs dozens of fibers multiplexed.

BTW, these are internet backbone aggregation technologies, no actual consumer would see this kind of cabling bandwidth in home local networking equipment for another 20 years.

A 57km cable. Boy. Just imagine how much faster this would make Windows!!

I get over 100mbs downstream and 100mbs upstream and my computer is no faster than the guy who has 50mbs up and down. (At least I cant see it) I dont upload that much) but most of my downloads are limited by the server I am downloading from , not my connection.

Where are you getting those speeds and which company?

Verizon and I pay through the nose, but I got over 100mbs downstream from my cable company. Only 2 upstream though.
