>Effect on fiber optics is zero.
Note that underwater cables carry a copper conductor to power the inline laser amplifiers. Would they pick up an eddy current 100m underwater? Probably not, but you'd hope they have disconnect switches at the beach landing hut, and someone on call 24/7 within 10 minutes drive distance to open them.
Without the amps, an undersea fiber cable is just an unusually long strand of glass.
- Johnythree 5y agoThe problem is large scale ground currents, eg currents of thousands of amps traveling through the ground. Which means that deeply buried (or underwater) cables are particularly vunerable. And of course that even happens today, eg the ground currents caused by electric trains and trams can be very destructive.
