In case you were wondering how fiber-optic FPV drones work in practice, this shows it pretty well (these are the types of ads i get nowadays, hah). Most FPV drones are controlled by radio frequencies, which can be jammed or disrupted quite easily these days, using Electronic Warfare systems jamming frequencies in a general area, or directional drone jammers like these:
These fiber-optic drones however have an actual physical connection to the controller, so control can only be cut off by actually cutting the fiber-optic wire (or actually shooting down the drone, of course).
