New Data Transmission Record — 14 Tbps

Posted by ryuzaki0 on from the that's-140-hi-def-movies dept.

deejne writes to alert us to a new bandwidth record: Nippon Telegraph and Telephone has announced data transmission at a rate of 14 terabits per second over a single optical fiber. The paper claims the previous record was "about 10 Tbps." In the new experiment, NTT sent data over 160 kilometers (nearly 100 miles) of optical fiber, in 140 channels of 111 Gbps each.

    Just to put 14 Tb/s in perspective, 1920 x 1080 x 32 bpp at 30 fps is about 2 Tb/s.

    Arthur C. Clarke wrote a short story that had the telephone networks becoming self aware when the network became sufficently complex. It's possible I tell you, the telephone networks just don't have the bandwi.......

    My title at work is actually 'Radiology Information Systems Manager', and I'm one of the people responsible for sending MRI images from hospital to hospital, handling video streams from telerobotic surgeries, and the like.

    Surprisingly, data demands in the medical environment aren't nearly as high as you might think. We routinely route MRI images from hospital to hospital with infrared and T1 connections. Those MRI images are actually only about 10MB each. We got ourselves a 1Gb/s imaging network at our hospital, and we don't use more than 10% of that bandwidth at any time. A home video camcorder can easily out produce our imaging equipment, in terms of pure data content creation. At best, the large community hospital I work at in NYC (700 beds) has about the same data networking needs as a small or medium sized digital television studio. Granted, at the hospital, we're much more concerned with *quality* of data content rather than *quantity* of data content. All things considered, we're much more concerned with quality of service than bandwidth.

    I'd expect these high bandwidth paradigms to be essential to the telecommunication companies as they need to deal with more users, and more video streams. Notice that it was developed by Nippon Telegraph and Telephone, a company which is much more concerned with bandwidth of major pipes between cities. This will get applications in data trunk lines between major cities, with last mile fiber optics to the hospitals rated in the gigabit speeds.

    At this point can we start using Bytes instead of bits to measure?

    or a 70 MPH trip this adjusts to 2.25 Million DVD's or 225,000 (100 disk spindles) Each Spindle Weighs 4Lbs
    I missed by an order of magnitude here... 2.25 M /100 = 22,500 so this moves it down to a 45 ton cargo . Which isnt even close to the heaviest load on the road.

    So while the new line isnt quite nothing compared to a truck, a truck can move more data 100 miles faster than the new link.
