Interesting article - http://news.yahoo.com/insane-process-connecting-world-undersea-internet-cables-155139609.html
There are 263 active cables that carry upwards of 95 percent of global Internet traffic

Underwater cables carried 51 billion gigabytes of data per month in 2013, and that figure is expected to swell to 132 billion gigabytes in 2018.

Currently, less than 40 percent of the worldwide population has any access to the Internet at all.

    One of my favorite books: A Thread Across the Ocean by John Gordon. It's about the first attempt for telegraph cables.

    When I started in electronics, there were 80 telephone voice channels from Oz to NZ provided by the undersea cable. By using TASI (time assigned speech interpolation) they were able to increase this (to 120???). Extra capacity was now by satellite and big "earth stations".

    When I lived in Guam we would go scuba diving frequently at Gun Beach. There was a communications cable that we would follow out through a cut in the reef. On the way back we would use the cable to pulls ourselves in against the current. That's about all I know about undersea cables.

    Oh, that and if they wash up on your deserted island after a storm you can cut into them, call people with a coconut phone and then repair them with other natural island materials.

    I forgot about that book. it reminds me of the steamship "Great Western"
    The "Great Western" is the greatest Side Wheel Steam/Sail Ship ever built... They didn't need coconuts or bamboo to make the thing work.

    I sounds like you learned that on Gilligan's Island.

    There is a major internet cable that enters Taiwan about an hour south of where I live. It was damaged back in 2010 and everything got a bit slower.

    Yes, the Professor was a genius. He could make a radio out of a coconut.

    Yet curiously, he couldn't fix a hole in a boat.

    Ttailspin that is the Great Western.

    The largest ship ever at it launch. It was so inefficient and hungry for coal that it was far too expensive to run as a passenger liner. So it was converted for cable laying duties.

    That must be why it reminded me so much of the Great Western. :innocent:

    I've got Side Wheeler on the brain right now, My current project is all about Paddle Wheels...And Rudders of course.

    He probably could have. But then Ginger would have been gone from his life.

    An excellent book...it should be required reading in college for all engineers.
