I think that electrical cables have pretty low current. The fiber optic ones need to power amplifiers, so they have quite a bit of power going through.

- jimktrains2 12y agoI guess I figured copper wire would also required amplification.
- usbreply 12y agoYes, copper cables have repeaters too. And I would expect them to work at similar voltages. The only difference I can think of is that the amplifier power is probably a steady DC (and corresponding magnetic field) whereas the signal in copper will be varying voltages - creating a fluctuating magnetic field that repels the sharks ?
