Russia may have used `invulnerable` UAVs to bypass Ukraine's electronic warfare 0
(Dan Tri) – Russian forces in Ukraine may have used suicide UAVs controlled via fiber optic cables instead of wireless connections, making them `invulnerable` to Ukrainian jamming equipment.

War Zone reported that Serhii Flesh, a Ukrainian soldier with expertise in `radio technology`, on March 7 was the first person to post a photo on Telegram of a first-person view (FPV) drone.
It is currently unclear at what time and location the FPV was seized.
In the photo shared by Flesh, the label on the fiber optic tube body shows that the total wire length is more than 10.8km.

In addition to being connected to fiber optic cable, the UAV in Flesh’s hand has a similar structure to the types of FPVs used by both Russia and Ukraine.
UAVs are weapons widely used in the Ukrainian battlefield.
But with UAVs using fiber optic cables as a data transmission method, the signal cannot be blocked by electronic warfare.
Using fiber optic cables to remotely control equipment is not a new concept.
In the Telegram post, Flesh noted that fiber optic cables could allow operators to receive larger and faster amounts of data from UAVs, including higher quality video data.
Another advantage of the fiber optic control mechanism is that the device does not emit energy, helping users at a distance not be detected.

However, controlling a UAV via wire can also create disadvantages.
FPV’s effectiveness is largely due to its high maneuverability, but fiber-optic lines can become entangled in obstacles, become tangled in the drone’s own propellers, and limit the ability to quickly change direction or operate.
This is further emphasized by the fact that wire-guided anti-tank missiles are often used in conditions where the shooter has a clear line of sight to the target.
Tether-guided FPV drones will likely be most effective in areas with open terrain, such as settled frontline areas.
Wire-guided FPVs will also be effective when used in near-frontal attacks, or when used as patrol ammunition at short distances.
