Terabit Fiber (In 2010)
Paul Heavens writes "A Japanese company has developed technology to transmit a two-hour movie in 0.5 seconds, the world's fastest speed achieved with fibre-optic cables in the field, it says. Kansai Electric used fibre-optic cables on power-transmitting steel towers to achieve the speed of one terabit per second, which is more than 100 times faster than inter-city data transmissions currently in use, a spokesman says. The company, Japan's second-largest power supplier, has not decided when to put the technology into practical use but says it is possible that it would come in 2010 or later."
You guys sure know how to bait the MPAA here, don't you?
could you bump your mtu to 2937498723498, I don't want to keep fragmenting these...
Click here or here.
If you throw a 500GB harddrive fo the empire state building, it's not only faster moving data that this, the data is accelerating.
:)
Beat that, japan
That "story" is ridiculously short. What I want to know is, was that over *one* strand of fiber, or a big bundle of fibers with each at a non-record-setting speed?
1) They didn't transfer 1 Tbit/s in an actual network, at least it appears that way if you RTFA. I am more impressed with Bell Labs 100 Gbit/s in actual ethernet reported a few weeks ago. As far as I know they could have measured the rate photons got from point A to point B in the cable, worthless statistics, like measuring the speed of electricity.
2) According to other news entries like RTFA, they don't contain any info whatsoever about how the company actually conducted the test. One source, Returters IIRC, says it's "secret". Right.
What do you mean? When I was a kid, fiber cable was just a novelty you read about in Popular Science. They claimed that it had the potential capacity to transmit things like War and Peace in just a few seconds.
Well, guess what: Today, in the comfort of your own home, you can download War and Peace in just a few seconds.
Now we humans just need a way to watch that 2 hour long movie in 0.5 seconds
Over the years, I've been tracking the waiting attention span on my downloads and those who got from me. I've ran BBSes since 1200 baud modems were $500.
The 3 minute mark seems consistent over the years as the shortest period of time necessary to acquire something of value. Shorter times are nice but not needed.
To download a 2 hour HiDef movie in 3 minutes, we'd need a connection speed of 222mb/s (28MB/s). I can see little need for a format beyond this at any time in the future. In fact, in 1993 I figured a preferred video resolution would be 2560x1440, not much greater than 1920x1080.
We'll soon see posts about how corporations won't want to spend money running these fibers to the home, but this is pure bullshit. Cities prevent more cable runs, not economics.
Municipal Wi i is a huge waste due to ever increasing wired bandwidths and the costs and latencies of government changes would never keep up with free market changes.
Allow ISPs the freedom to run fiber. Deregulate TV and radio frequencies in exchange for more wireless frequencies. You'll see the most amazing growth of information distribution in history.
Mabey by then I could get DSL in my area.
Umm... so because people are unwilling to spend that kind of money, the FCC should force them to spend that kind of money through taxes? Besides, I don't want this. I'd be happy with 100Mbit (network, 100/100) to the wall. That's not in the "never have" category, it already exists in places like South Korea, Japan, many university campuses and certain apartment blocks here (Notway). There was a time not too long ago, when the main interconnect to my city of 150000 was 2.5Gbit, that has probably changed by now. But that is 25 people maxing a 100Mbit connection. Solutions such as these make sure I don't sit there with lots of bandwidth and nowhere to go. 1Tbit isn't all that much if hundreds of million of people try to transfer something over it...
Live today, because you never know what tomorrow brings
0.5 seconds? But I want it now!
