Transpacific Unity Fiber Optic Cable Leaves Japan

JoshuaInNippon writes "The 10,000 km (6,200 mile) long Unity fiber optic cable, funded by Google and five East Asian communication companies, left Japanese shores on November 1st to be laid along the northern Pacific Ocean floor. The Japanese end of the cable is expected to be fused to the American end sometime around November 11th. The cable, which was announced in February of 2008 at a cost of around $300 million USD, has the theoretical capacity of 7.68 Tbps, but will be set at a capacity of about 4.8 Tbps (supposedly equivalent to about 75 million simultaneous phone calls) during its initial use. When Unity begins full operation sometime early next year, it is projected to increase internet traffic capacity between the two regions by over 20%, a wonderful boost to transpacific relations!"

      That maybe fine for you, but here in Japan the Internet is basically one big LAN.

      So basically we have so much of the stuff tentacles are poking out of our USB ports.

      What that does mean for us, here in the land of Hello Kitty, is faster access to a range of porn featuring fewer celaphods and more girls with non-pixelized genitals.

  4. How does that work, exactly? by wandazulu · · Score: 4, Interesting

    So I've got a bunch of cable laying around, figure I'll run my own line from Japan to California. How does that work, exactly? I assume the cable is protected in some extremely strong waterproof and snag-proof sheath, but do they really just roll it off the ship, let it fall to the ocean floor, and there it sits? Do they have to occasionally throw a repeater overboard as well? I've always been curious how we're actually able to have these outrageously long cables under the sea and that it works, and works well enough that I believe cables are still the preferred method of data movement, with satellites being a distant second.

      Yes, you need repeaters every 100km or so, which are powered through the cable by DC current.

      Other than that, I think it just lays in the bottom, yes. These are sturdy cable, they weigh about 10 kg/m.

      Yeah screw the article, here is a video and they speak a thousand words. Very cool to actually see the cable being pulled out and what the repeater looks like.

      Don't forget sharks, that seem to be fooled by the electric field that results from the DC current powering the repeaters, and occasionally attack the cables. I believe newer cables include upgraded armor that is more shark-resistant.
