Submarine Cables

1. Is it true that sharks biting the cables is a problem?

  • Cables do fail pretty often, but most of the time it gets cut or snagged by a fishing boat, or gets destroyed by natural occurrences such as earthquakes or strong tides.
2. Cables can break just by wearing out - but what are some other things that cause them to break?

  • Boats or submarines can cut them, as well as other natural disaster such as a tidal wave or earthquake.
3. Who uses submarine cables?

  • Everybody who uses the internet uses these cables, especially if you are trying to reach a server that is on another continent. 
4. How thick is a cable?

  • A cable is typically the diameter of a garden hose but the fibers inside them are about as thick as a human hair.
5. How does fiber-optic technology work with the cables?

  • Lasers fire light down the fibers and a receptor on the other end of the cable picks it up. Since the speed of light is very fast, it does not take long at all, even on the longest cables.
6. What did you find most interesting about the cables?

  • I thought it was crazy just how many they are and that so many people don't even know they exist. I also thought the fiber optic technology was really cool because I hear about it in commercials all the time but never really know what it means.
