Fiber optic drone
A fiber optic drone is an unmanned aerial vehicle (UAV), usually a first-person view (FPV) loitering munition, which uses an optical fiber as its primary guidance and teleoperation link. These drones usually have fiber optic cables between 5 and 20 km (3.1 and 12.4 mi) long, although prototypes with up to 50 km (31 mi) range have been developed.
