Google has to wrap its underwater fiber cables in a Kevlar-like material to protect against shark attacks. The material is a synthetic material of high tensile strength-to-weight ratio, which makes it 5 times stronger than steel on an equal weight basis. A 1987 story from the New York Times describes how an experimental fiber optic cable laid off the Canary Islands was being chomped on. Google recently announced that it was investing in a new, $300 million undersea fiber optical cable system running between the US and Japan.”]
