Fiber-Optic Drone Defense
Jam-proof fiber-optic FPV drones — proven across the Ukrainian battlefield and now fielded against northern Israel — defeat every RF-based counter-drone system. Cherev builds the layered detection, interception, and operator training that actually stop them.
What Is a Fiber-Optic Drone?
A fiber-optic drone is a first-person-view (FPV) attack or reconnaissance drone that flies trailing a hair-thin spooled optical fiber instead of a radio link. The fiber carries both flight control and live HD video. Because the drone emits no radio signal, it cannot be jammed by electronic warfare and is invisible to RF detection. Fiber tethers run 5–20 km today, with next-generation models reaching 50–100 km.
This breaks the entire deployed counter-drone playbook. RF jammers, RF direction-finders, and GNSS-denial systems detect and defeat drones through their radio emissions — a fiber-optic drone has none. Defenders across the front report fiber drones flying straight through "protected" electronic-warfare bubbles. The only exploitable weaknesses are physical: the spool adds weight that cuts speed and maneuverability, the trailing fiber can snag or be cut, and the airframe is still visible to optical, thermal, and radar sensors.
Moving the Kill Chain Off Radio Frequency
If you cannot jam it, you must see it, decide, and defeat it. Cherev integrates a layered, non-RF counter-FPV capability and trains the crews who run it.
AI Optical & Thermal Detection
Passive electro-optical and thermal (EO/IR) sensors with AI vision that see what radar and RF cannot — the only reliable way to spot a fiber drone that emits no signal.
- EO/IR + AI target recognition
- Radar + EO/IR sensor fusion
- Day, night & degraded conditions
Kinetic Interception
Because the link can't be cut electronically, the drone must be physically defeated. We integrate interceptor-drone, net, gun, and directed-energy options into a coherent defeat layer.
- Interceptor-drone employment
- Nets, guns & cable-cutting rigs
- Directed-energy & laser options
Counter-FPV Operator Training
Counter-FPV is a detect-decide-engage problem measured in seconds. Built on our Keshet Yehonatan platform, our injury-free simulation builds the crews who win that window — with real-time analytics and after-action review.
- EO/IR cue-recognition drills
- Engagement decision under stress
- Unlimited, injury-free repetitions
Battlefield-Lessons Doctrine
We convert frontline counter-FPV lessons — Ukraine's interceptor tactics, route overwatch, dispersal, overhead cover — into doctrine, drills, and force-protection SOPs your units can use now.
- Route overwatch & dispersal
- Layered force-protection SOPs
- Rapid doctrine iteration
The Counter-FPV Kill Chain
Three steps, none of them radio-based — and all of them dependent on a trained crew.
Detect
See it without radio. Passive EO/IR and AI vision, fused with radar and acoustic cues, find a target that emits no signal.
Decide
Confirm and prioritize in seconds. Trained crews classify the threat and choose the right effector before it closes the distance.
Defeat
Stop it physically. Interceptor drones, nets, guns, cable-cutting, or directed energy end the threat — the link can't be jammed, so the airframe must be killed.
EMP & High-Power Microwave: When Jamming Fails, Fry the Electronics
Jamming can't touch a fiber-optic drone's glass link — but the drone is still a flying computer. Electromagnetic-pulse (EMP) and high-power microwave (HPM) weapons fry the flight electronics directly: the one electronic path to a kill that jamming closed. Israel already leads here — Rafael's Iron Beam laser and high-power microwave systems, fielded in Gaza, now anchor a layered directed-energy response. In December 2025, an HPM system became the first to bring down a fiber-optic drone in a documented test.

Founded by veterans of Israel's special forces, Cherev translates frontline lessons — from Ukraine to the northern border, and from October 7th onward — into counter-FPV solutions and training. We do not sell a single magic box. We assess your real RF-blind gaps, integrate layered detection-to-defeat, and build the operator readiness that turns hardware into protection.

Fiber-Optic Drone Defense: Key Questions
An FPV attack or reconnaissance drone that flies trailing a thin spooled optical fiber instead of a radio link. The fiber carries flight control and live HD video, so the drone emits no radio signal — it cannot be jammed and is invisible to RF detection. Tethers run 5–20 km, with newer models reaching 50–100 km.
