Cross section of an undersea cable

  1. Doesn't look like any data cable I know of. If I had to guess, it's a power cable in three phase, with fairly high voltage considering the massive dielectric shield around the copper. Anybody more knowledgeable got a better idea?

    1. Agreed. Power transmission. Otherwise you couldn't get more than one phone call through.

  2. Right you are, Greg. The cross-section is for a power cable with integral shielded grounding. The small circle in the upper left looks like a coax cable used for signaling between monitor points in the transmission line. Telecom cables are much smaller and all those in the past ~20 years are combinations of several fibers in amongst a fair number of strength members and polymer seals.

  3. It'd make a nice wall hanging in someone's den.

  4. "The Cable" (Gillian Cookson) interesting book on the first trans-Atlantic telegraph cable; the people, the technology, the success and the failures.
    Putting it into focus for it's place in time and history; one message alone sent by the British government made the governments investment back with interest. Though the Crimea War had ended, a Canadian regiment was about to sail for the Crimea and an undersea telegraph message stopped them.

  5. I thought undersea cables were optical fiber bundles.
