    the basics....

    "Researchers reporting in Nature Photonics suggest putting not one beam of light down a fibre, but a pair, each a kind of mirror image of the other.

    When recombined on the receiving end, the noise that the signals gather in the fibre cancels out.

    These paired beams can travel four times farther than a single one.

    The team used the technique to send a signal of 400Gb/s - four times faster than the best commercially available speeds - down 12,800km of optical fibre, farther than even the longest trans-oceanic fibre link."

    Dunno... I just doubled mine with my DSL carrier, went from a 6G to a 12G for the same price. I'd say they'll keep pushing the price up as much as they can as long as they can get away with it...
