How are internet cables able to withstand the devastating pressure at the ocean floor? Will it not be destroyed?
In: Engineering
They are solid through and through. Solids are not really compressible. You are thinking of a submarine getting crushed. But there’s the difference – in a submarine, you have to maintain a pressure difference between inside and outside. You want your crew in normal pressure air. That creates a force on the hull. In a cable, there is no such pressure difference.
