    Meanwhile my ISP refuses to upgrade my upload speed beyond 12mb while I have 120mb download...

    Yah i have 400mbit that only 20mbit up, and my isp 1gbit is still 20mbit up an price jump from 400 to 1gbit is extra $40 month, can you image what we would be charge for such speeds? not that we have storage that could even cope with such speeds and even if we did it probably cost limb or 2

    Crazy stuff when you stop to consider that even ultra-high end enterprise kit runs around 100-400Gb/s. Obviously this article's tech is geared at ISP usage for backbone or otherwise but it is still insane to think that that sort of throughput is even possible.

    While impressive speeds its all thanks to their use of 4 core fiber that they have made. While the fiber can be interesting, especially if its commercially viable, its basically a fancy spacial division multiplexing, so not that groundbreaking concept.

    What grinds my gears is that even if you're on coper cable the latest DOCSIS can get good bandwidth. That said, most coper cable operators are changing the major lines to fiber, so hybrid coper/fiber networks are being installed for even greater speeds!
    And for fiber connections if the ISP don't at least match the down with up they're just milking us. Vodafone has some good deals, but no connection at my door...

    the speed is set in Tbit , not TByte
    the actual speed is 3MB/s , but over that distance it's quit the achievement

    you are way way wayyyy off ! 1 byte = 8 bits ! 319 Tbits /8 = 39,875 TBytes ! your estimation of 3Mbytes /sec is only off by a factor of 13.291.667 ((yes 13 million :p ))
