It is very unusual for there to be any interference whatsoever between electrical circuits and fibre-optic cables.

The fiber optic cable must be kept full at all times. If the level drops below 75% you might get some interference at around 1.1 times the frequency at 22kv.

You will need demonic isolators if this is the case.

Forgive my ignorance, but a Cathode Ray Tube (television) springs to mind. Could not a sufficient magnetic field distort the path of photons, such as those within fibre optic cables. I assume it doesn't seen as it's 99.99% internally refractive??

The fibre optic cable must be kept full.......hehe good one

Whoa! I have to correct the haneous confusion of sub atomic theory I just blurted out. Obviously fibre optics is not concerning electrons such as in a CRT. I really shouldn't type things that "spring to mind".
