Deep Trouble

An experimental undersea telephone cable in the Canary Is­lands had to be lifted from the ocean floor three times because of breakage. Each time sharks' (акула) teeth were found in the dam­aged cable. Though the cable contains optical fibres transmitting signals in the form of light, it carries a very small amount of electri­cal wires. It is known that electricity attracts sharks. Therefore, or­dinary electric power cables are usually provided with some kind of protection to stop their being attacked by sharks. However, it was not expected that it was necessary to mount this expensive protec­tion on the new cable. But provided the designers had used this conventional protection on the new cable, the sharks would not have approached it.
