Sharks take a bite of Google’s undersea cables
Google has had to reinforce its fragile undersea internet cables with a material similar to that used in bulletproof vests – partly to protect them from curious sharks.
The Telegraph online says this was announced by the massive technology company at its Google Cloud Roadshow event last week.
The Telegraph reports that Google owns about 160 000km of private fibreoptic cable around the world.
Fibreoptic cables use lasers to send data across the ocean, allowing transfer rates up to 100 times higher than traditional copper cables.
But they are made of fragile glass strands and must be protected from any knocks or sharp movements.
At the event, the Telegraph reports, Google said it was now using a “Kevlar-like material” to protect its cables.
For unknown reasons, sharks seem drawn to the data cables that rest on the ocean floor. One attack was even caught on camera.
In 1985, shark teeth were found buried deep in the coating of an experimental fibreoptic line near the Canary Islands off the northwest coast of Africa. – Staff reporter
