Nets, Fire Teams, and Lasers: Inside the Fight Against Fiber-Optic Drones - VGI-9
AI Analysis
The increasing use of Electronic Warfare (EW) has driven the adoption of fiber-optic drones, which are resistant to jamming. Countermeasures currently focus on low-tech solutions like anti-drone netting and mobile fire teams due to the ineffectiveness of traditional EW against fiber-optic communication. These tactics are being actively deployed in Ukrainian frontline areas.
Key Takeaways
- Traditional radio-controlled FPV drones are becoming less effective due to widespread EW use.
- Fiber-optic drones offer a solution by utilizing physical cables for control, bypassing radio interference.
- Anti-drone nets are a scalable and practical countermeasure, deployed over roads, dugouts, and equipment.
- Net effectiveness relies on complete coverage; gaps allow drones to penetrate.
- Mobile fire groups equipped with small arms and observation tools are being used for drone detection and physical destruction.
Why It Matters
The emergence of fiber-optic drones represents an escalation in drone warfare, requiring adaptation in defensive strategies. The reliance on physical countermeasures highlights a temporary gap in dedicated C-UAS technology capable of defeating this new threat, potentially influencing procurement priorities. This shift necessitates a focus on both physical protection and development of new detection/interdiction methods.

The widespread use of electronic warfare (EW) systems on the battlefield in 2023–2024 significantly limited the effectiveness of traditional FPV drones controlled via radio channels. Under conditions of active signal jamming, operators lost control of UAVs, which reduced their operational efficiency.
In response to these limitations, fiber-optic drones began to be actively deployed. In such systems, communication between the operator and the drone is not transmitted via radio waves but through a thin fiber-optic cable that unspools during flight. This solution allows stable control even in areas with intense EW activity and effectively eliminates the impact of radio interference on the communication channel.
Fiber-optic drones became one of the most discussed topics in mid-2024, and their numbers have only continued to grow since then. They have gained a reputation as one of the most effective weapons. But is that really the case?
Countermeasures: What Actually Works?
Fiber-optic drones have undeniable technological advantages. However, they are not completely invulnerable. Traditional electronic warfare methods do not work against them, which limits the range of effective countermeasures.
Why are fiber-optic drones getting so much attention? In a separate piece, we break down how they could impact the course of the war.
Military units are developing practical solutions — from engineering barriers to tactical approaches and physical destruction of drones. Below are the countermeasures already being applied in practice to reduce the threat posed by such systems.
Protective Nets
One of the simplest yet quite effective countermeasures against FPV drones is the use of physical barriers — specialized anti-drone nets. These passive engineering solutions are increasingly common: nets are stretched over positions or roads to physically block drones from reaching their targets.
Today, such protection can be seen across many frontline areas. Roads between Druzhkivka and Kramatorsk are covered with nets, and similar structures are deployed in Dnipropetrovsk, Donetsk regions, and beyond. Military experience shows this to be one of the most scalable and practical solutions.
Nets are not only used over roads. They are also effective above dugouts, shelter entrances, and equipment positions. Installed on metal cables or poles, they form a kind of “dome.” When a fiber-optic drone hits such an obstacle, it either detonates prematurely or becomes entangled before reaching its target.
However, nets are not a universal solution. Experts note they are only effective with dense coverage — even small gaps can allow drones to pass through.
Mobile Fire Groups
Another method of countering fiber-optic drones is the use of mobile fire groups. These units consist of several soldiers equipped with small arms and observation tools. Their task is to detect drones quickly and
