The unjammable drone tether — why G.657.A2 matters

The war in Ukraine has revealed a fundamental truth: every RF-controlled FPV attack drone can be jammed. Both sides have deployed extensive electronic warfare (EW) systems that disrupt the 2.4 GHz, 5.8 GHz, and 900 MHz control links used by conventional FPV drones. In response, both Russian and Ukrainian forces have pivoted to fiber-optic tethered FPV drones — small quadcopters or fixed-wing UAVs that carry a spool of ultra-thin fiber optic cable that unwinds as they fly.

These drones are completely immune to EW jamming because their control signal travels through a physical glass fiber, not over the air. The trade-off: the drone is limited to the length of fiber it carries, typically 10–20 km.

The specific fiber that makes this possible is ITU-T G.657.A2 bend-insensitive single-mode fiber. Its exceptional bend tolerance (down to 7.5 mm radius) means the spool can pay out at high speed without the fiber breaking, and the drone can manoeuvre aggressively without signal loss.
