Shark Week on Discovery always brings a lot of attention to the whole shark area. But are shark attacks to undersea fiber optic cables a significant threat to the world’s optical transport networks? An old YouTube video receiving a lot of renewed interest would indicate yes. https://www.youtube.com/watch?v=1ex7uTQf4bQ&feature=youtu.be The video appears to show a six-gilled blunt nose shark chomping down on a submarine cable.
This new interest shark versus fiber optics was significant enough to prompt a response by the International Cable Protection Committee (ICPC). They reassured us not to worry. They closely track undersea fiber optic cable faults and their causes. Less than 0.5% of cable faults appear to be caused by fish bites. There is no need to worry that Jaws is going to disturb your next NetFlix or YouTube viewing session.
