Ukraine has begun using a new fiber-optic anti-drone device on the battlefield.

It works by cutting the cables through which operators control the drones.

The technology comes at a time when militaries around the world are looking for ways to protect themselves from these drones.

The Ukrainian Chaharnyk (“bush”) device, introduced in September, is designed to physically sever the fiber-optic cables used to control many FPV drones.

Unlike drones that are controlled via radio signals, fiber-optic drones cannot be stopped by blocking their electronic signal.

They have also been used recently in the conflict in Myanmar, as well as in deadly attacks against Israeli forces, A2 reports.

Their use has also prompted Israel to intensify efforts to find effective ways to protect itself from them.

The director of the Ukrainian company, Logika Design Bureau, which developed the Chaharnyk device, told Radio Free Europe that "dozens" of such systems have been delivered to Ukrainian units on the front lines in recent days.

He declined to be identified for security reasons and said it is "still too early to talk about official assessments or statistics" regarding the effectiveness of these devices on the battlefield.

The chaharnyk resembles a cattle fence and is about 80 centimeters high.

When its acoustic sensor detects a drone in the vicinity, the system is activated: electric motors set in motion wires equipped with sharp hooks, similar to barbed wire, in a special area for capturing and cutting the cables.

The manufacturer did not provide details on how this part of the system works.

When the fiber optic cable is caught and cut, the physical connection between the drone and the operator controlling it is severed.

James Patton Rogers, co-director of the Future Threat Lab at King's College London, likens Chaharnyk to "intelligent barbed wire."

He predicts that the device could face significant problems in an active war zone, including the risk that the system itself could become a target of attacks.

Also, depending on where it is placed, it could also hinder the movement of Ukrainian forces, according to him.

However, Rogers emphasizes to Radio Free Europe that "if deployed along the front line or around villages, residential areas and important military facilities, alongside other anti-drone technologies, it could provide vital protection against a threat that has not yet been neutralized."

During demonstrations of the system, fiber optic cables that pull FPV attack drones behind them are caught in Chaharnyk's hooks and then pulled towards the cutting mechanism.

The Logika company claims that the system succeeds in severing cables in 95 percent of cases.

But cutting the cables does not necessarily neutralize the drone.

The head of the Ukrainian company Logika told Radio Free Europe that many Russian FPV drones, which are controlled via fiber optics, also have a backup radio connection.

If the cable is cut, the drone switches to that alternative mode of communication.

"In that case, electronic warfare systems deployed in the area are activated," he said, adding that "in most cases, the drone crashes and explodes."

A recent Chinese report on anti-drone technologies analyzed an improvised obstacle, similar in principle to the Chaharnyk, which was filmed being used in Ukraine in late 2025.

According to the Chinese report, this improvised system had "clear" limitations.

The pilot can steer the drone around the obstacle; cutting the optical fibers does not necessarily avoid the hit, as the drone can continue moving and crash into the target; while the placement of the obstacle itself can reveal the area where the defense forces are operating.

"Can the opponent spot Chaharnyk and bypass him? Yes, that is possible," the head of the Logika company told Radio Free Europe.

"However, if a network of these systems is properly deployed, taking into account the object or area to be protected, there will be no way to bypass it," he said.

These statements imply that among the first positions where this technology could be deployed are small Ukrainian points on the front line, which are regularly attacked by FPV drones.

The head of Logika added that the system can be camouflaged.

According to him, even the low-resolution images that drone operators see can make it difficult to distinguish the device from a distance.

"We are not claiming that Chaharnyk will protect everyone, but we are confident that it will improve protection against attacks by FPV drones that are controlled via fiber optics," he said. (REL)
