Undersea fibre optic cables carry data across continents at up to 1 Gigabit per second, which is around 100 times faster than the older copper cables. In the Pacific, surveillance video of a shark biting these cables has led Google, and it's partner companies, to reinforce the cable with Kevlar-like coatings to prevent damage from shark bites. The older copper cables did not attract the same attention from sharks as the new fibre optic cables. This could be because of the magnetic field created by the high voltage carried through fibre optic cables is similar to that produced by fish. Although most of the cables already have shielding to prevent electrical transmission outside of the protective layers, some electrical and magnetic fields may be able to expand beyond the cables protective covering.
