Inside the fiber-optic FPV that beat the jammers

Electronic warfare made radio-controlled FPV drones unreliable over contested ground. The fix was almost absurdly low-tech: replace the radio link with a physical fiber-optic cable that pays out from a spool as the drone flies.

Because the control signal never touches the electromagnetic spectrum, jamming has nothing to grab. The trade-off is range and weight — but field tests now put effective range well beyond ten kilometers.

This report reconstructs a single, geolocated engagement to show how the system performs when the theory meets terrain, weather, and a moving target.
