On the Ukraine-Russia front line, to deal with the Russian fiber optic FPV suicide drones that are wreaking havoc, the Ukrainian army has demonstrated a low-cost passive solution. They took wires from a barbed wire fence, straightened them and fixed them on a support pole, using a small motor to make this blade-like wire rotate continuously. If a fiber optic drone flies over, the fiber released from its fiber optic tube may be cut by the rotating blade wire.
This solution is somewhat feasible, but it needs to be deployed in large numbers in open areas, and maintenance issues also need to be resolved. It must ensure that the small motor keeps rotating.
