The armored tube that carries 99% of intercontinental data/Technology
Submarine communications cables are laid on the ocean floor and carry over 99% of intercontinental data traffic. A typical deep-sea cable is only about the diameter of a garden hose, with optical fibers at the center surrounded by layers of steel wire, copper, and polyethylene. Repeaters every 60 to 100 km amplify the signal.
