Russian fiber-optic UAVs are almost always successful, causing great suffering to the Ukrainian military. It's unclear who gave the Ukrainians an idea. Picking up the communication fibers left by Russian fiber-optic UAVs and feeding a beam of light into the equipment immediately opens a clear path to the Russian UAV operator position.
However, this method is both useful and not so useful. Because there are too many Russian fiber-optic UAVs, and the Ukrainian military is also extensively using fiber-optic UAVs. Among the many communication fibers on the ground, it is difficult for you to find which one is the correct one you are looking for.
Moreover, this method can only be used at night, and the tangled communication fibers need to be straightened out. The key point is that the battlefield is too chaotic, with all kinds of vehicles, explosions, fires, and many of the communication fibers on the ground are fragile, damaged by explosions, trampling, etc., on the way.
Now, the Ukrainians are studying that Russian fiber-optic UAV operators transmit wireless signals when controlling UAVs.
And because of the problem of line length, fiber-optic UAVs have very limited range, just up to 5 kilometers or 10 kilometers. Using electronic reconnaissance systems, it may be possible to discover a nearby weak-power but stationary wireless signal.
