A working fiber will transmit those pulses all the way across the ocean, but a broken one will bounce it back from the site of the damage. By measuring the time it takes for the reflections to come back, the engineers can figure out where along the cable they have a problem.
Thereof How do they fix undersea cables? The ROVs can’t operate in deep water due to the increased pressure, so to fix a deep water cable, the ship has to use a grapnel, which grabs and cuts the cable, dragging the two loose ends to the surface. If needed, one end can then be hooked to a buoy and the other end brought on board.
Can Russia cut undersea communication cables? Chief of Defence Staff: Russia cutting underwater cables could be ‘an act of war’ Admiral Sir Tony Radakin said by targeting global communication cables, Russia could “potentially exploit world’s real information system”.
Similarly, Why do we need undersea cables?
Subsea or submarine cables are fiber optic cables that connect countries across the world via cables laid on the ocean floor. These cables – often thousands of miles in length – are able to transmit huge amounts of data rapidly from one point to another.
Where do undersea cables come ashore?
Do the cables actually lie on the bottom of the ocean floor? Yes, cables go all the way down. Nearer to the shore cables are buried under the seabed for protection, which explains why you don’t see cables when you go the beach, but in the deep sea they are laid directly on the ocean floor.
How deep are submarine cables laid? Modern cables are surprisingly thin, considering how long they are and how deep they sink. Each is usually about 3 inches across. They’re actually thicker in more shallow areas, where they’re often buried to protect against contact with fishing boats, marine beds, or other objects.

Why do sharks bite undersea cables? So why are sharks attracted to undersea data cables? It’s not exactly known. Some believe that because sharks can sense electromagnetic fields through jelly-filled pores on their snouts called ampullae of Lorenzini, perhaps they are attracted by this electrical current and confusing it for food.
How deep are subsea cables? Modern cables are surprisingly thin, considering how long they are and how deep they sink. Each is usually about 3 inches across. They’re actually thicker in more shallow areas, where they’re often buried to protect against contact with fishing boats, marine beds, or other objects.
