- sidewndr46 4y agoI don't think all Fiber optic is free from the effects of geomagnetic storms like the Carrington event. Lots of "fiber" also has copper along with it for critical telemetry and for powering repeaters placed directly into the cable assembly. If the repeaters burn up, the cable still fails. That being said, if a geomagnetic storm takes out fiber laid on the bottom of the ocean we're probably all going to be needing new chromosomes shortly anyhow.
- lxgr 4y agoFiber optics still need amplifiers every couple of kilometers – and to feed these, you'll need a metal-based electricity supply.
- BenjiWiebe 4y agoMore like 100km, I believe.
- lxgr 4y agoYes, but since in many locations in the world you won't find a power grid to tap into every hundred kilometers, that still means you'll effectively have a cable carrying both fiber and copper.
- dark-star 4y agofiber optics might give you data, but you cannot run power over them, and power lines are basically huge antennas... There's not a lot you can do to mitigate that
