Sharks bite Google submarine cables

There are many, many things that can go wrong when you put thousands of kilometers of fiber optic cable to the bottom of the ocean. Earthquakes, fishing hooks and even ordinary sharks can damage the cable. Sharks are, of course, nonsense.

According to Google Product Manager Dan Belcher, who spoke with Network World, Google plans to put its cable into a Kevlar shell to protect it from sharks chewing on the data line. It turns out that among those who put the cable on the seabed, it is considered to be quite an ordinary procedure to place the cable in a protective sheath in order not only to keep it from attacking fish, but also to preserve aquatic life.

Reporters asked Google representatives what they thought about the fact that sharks want to eat fiber optic cable, but they could not say anything. Perhaps the video below will help answer this question.

As Google expands its online empire, submarine cables are becoming an increasingly important part of the plan. The company has invested in the two largest submarine cables connecting the western US and Asia, and the third cable, which will expand the Google network in Asia. Cables are the bottleneck of today's data transfer, and the lack of fiber can seriously inflate the market prices for data transfer between two continents. Unless you have your own data cabling.

It is known that squirrels are a serious problem for terrestrial cables, but according to various reports, sharks and other fish remain surprisingly stable problem for a submarine cable. In the 1980s, deepwater fiber optic cable dropped four times. Researchers blamed crocodile sharks after they found teeth in a cable.

Cable protection people have no idea why sharks bite cables, although some suggest that this may be due to an electromagnetic field in a live cable.

Sharks, like other animals, can detect magnetic fields - and they have miniature voltmeters in their mouths, which they use to detect prey and bond with colleagues. However, there is a simpler explanation, says Chris Low, a professor at the Shark Lab at the University of California. It can be ridiculously simple.

“If you just throw a piece of plastic in the form of a cable into the water, there is a high chance of being eaten. But even a small bite is enough to tear the cable and damage the fiber. ”
