Cable designed to be placed underwater. Such cables must be specially protected against moisture. At shallow depths on continental shelves, submarine cables commonly are plowed in and armored to protect them against ship anchors, trawler nets, and sharks, which are attracted to the electromagnetic fields and like to gnaw on the cables and repeaters.

Modern submarine cable is all fiber-optic. It's about a foot in diameter. In it they run just a few strands of fiber optic cable. It's packed in Vaseline--seriously, that's what they use. Then it's wrapped in plastic, metal and fiberglass jackets for protection.In the cable are inline amplifiers that boost the signal.Now, in the OLD days before submarine cable went digital, each wire pair in a submarine cable carried 16 channels of communication, as opposed to 12 channels on a terrestrial link. They did it that way because submarine cable is so expensive.

Submarine cable is constructed in much the same way direct bury cable is made. The major differences involve "what" is done rather than "how" it is done. What is done is that a whole lot of extra armor and waterproof jacketing is added. Check out the information posted by our friends at Wikipedia by using the link. The pictures alone are worth the time.
