Reports of sharks attacking undersea fiber optic cables have actually been happening since the 1980s. This phenomenon is something that has recently caught media attention as footage of sharks aggressively biting undersea fiber-optic cables have resurfaced on the Internet.
Why do they do it?
There are over 60,000 miles of older copper wiring found under the depths of the sea but they seem to be ignored by the streak of aggressive shark attacks that have been reported over the years. One theory as to why sharks specifically attack fiber-optic cables instead of copper cables is that fiber-optic wiring radiates an electric current that activates a shark’s instinct to attack. Essentially, it mistakes these signals for a living organism, which it considers as prey.
Google owns valuable fiber-optic cables found under the sea that stretch for thousands of miles. These cables stream data and information all over the world. Without these cables, the high-speed Internet we enjoy would not be possible. Some of the wires with their outer jacket are just as small as a typical garden hose, which is why this valuable hardware needs to be protected from all kinds of damages.
Protective coating applied
Google is reinforcing fiber-optic cables with what’s described as Kevlar-like material, which serve as a buffer and protective coating. With the company partnering with Asian telecoms in order to build FASTER, a new and highly sophisticated a trans-Pacific cable, taking proactive measures in minimizing threats to this infrastructure is wise. The new cable will provide high-speed connectivity of up to 60 terabits per second and will cost around $300 million dollars to construct.
Aside from shark attacks, undersea cables are susceptible to damage caused by human activity. In fact, sharks don’t even come close to us humans – one of the biggest causes of cable damage is ship anchors dropping on them as well as large-scale fishing activities.
