Ukraine Adapts to Fiber-Optic Drone Demand Amid Conflict

The use of fiber-optic drones on the battlefield has become a common sight in Ukraine, particularly since the full-scale Russian invasion began in February 2022. These drones are physically connected to human operators by miles of thin fiber-optic cables that can withstand electronic warfare jamming and provide clear first-person view footage.

As the conflict escalated, Ukrainian forces found themselves facing off against Russian troops equipped with similar unjammable fiber-optic drones. The Ukrainians quickly adapted their tactics and began developing their own fleet of these advanced drones to counter the Russian threat.

The reliance on Chinese suppliers for drone components has become a crucial factor in the development of Ukraine's fiber-optic drone program. Bulk orders of fiber wound around large spools or small finished spools have been imported from China, allowing Ukrainian drone makers to equip their machines with enough cable to operate at ranges of dozens of miles.

Estimates suggest that Ukraine and Russia are producing an estimated 50,000 fiber-optic drones per month, resulting in a significant demand for optical fiber. This has created a logistical challenge for the manufacturers, as they struggle to meet the needs of both countries amidst growing competition from other industries.

The global market for fiber-optic cable is being driven by the rapid growth of artificial intelligence data centers, which also require large amounts of high-quality fiber to operate efficiently. As demand from these centers increases, it has become more expensive and difficult for Ukraine to import the necessary materials.

Ukrainian drone makers have been forced to adapt to this new reality by finding alternative suppliers or developing their own domestic production capabilities. However, this process is likely to be slow and costly, given the complexity of manufacturing high-quality fiber-optic cables.

The disparity in fiber-optic imports between Russia and Ukraine has become apparent, with China's official customs data revealing significant differences in import volumes. For example, in August 2025, Russia imported a staggering 328,000 miles of fiber-optic cable from Chinese companies, while Ukraine received just 72 miles.

As the conflict continues to unfold, it remains to be seen how Ukrainian drone makers will navigate this complex web of global supply chains and emerging technologies. The challenges they face will likely have far-reaching implications for the development of military technology and the role of fiber-optic drones on the battlefield.

The global demand for optical fiber has skyrocketed in recent years due to the rapid growth of artificial intelligence and data centers. This surge in demand has put a strain on the supply chain, leading to shortages and increased costs for countries that rely heavily on this technology.

One country that has been particularly affected by these changes is Russia, which purchased over 37 million miles of fiber-optic cable last year. According to industry reports, this accounted for more than 10 percent of global demand, a significant increase from the previous year when it made up less than 1 percent.

The shortage of optical fiber has far-reaching implications for various industries, including military technology. The expected shortfall of 111 million miles in 2026 will only exacerbate the problem, leading to higher costs and potentially delayed projects. This development is particularly concerning for countries like Ukraine that rely on fiber-optic drones for their military operations.

Ukraine's BlueBird Tech is one company navigating these supply-chain challenges. As a manufacturer of various military drones, including fiber-optic models, they are well-positioned to comment on the current state of the industry.

In an exclusive interview with Ars, Oleksiy, a representative from BlueBird Tech's R&D department, discussed the evolution of fiber-optic drone technology. According to Oleksiy, these drones have several distinct advantages over traditional RF-controlled models, including their ability to evade detection by conventional systems.

Fiber-optic drones are designed to operate in environments where traditional drones would be easily detectable. However, they also come with unique limitations and requirements for pilots. As Oleksiy noted, transitioning from a traditional drone to a fiber-optic model requires specialized training and experience.

The challenges posed by the shortage of optical fiber will likely have significant implications for military technology development in the coming years. As countries like Ukraine continue to rely on fiber-optic drones, they must also contend with the difficulties of sourcing these critical components.

The limitations of fiber-optic drones become apparent in certain battlefield conditions, particularly those involving electronic warfare. In these situations, conventional radio-controlled FPV drones have become increasingly difficult to operate due to the high density of electronic intelligence and warfare systems.

Fiber-optic technology offers a solution for operating in such environments, but it also comes with its own set of limitations. The use of fiber-optic drones has become widespread on both sides of the conflict, yet they still account for a smaller share of overall drone usage compared to radio-controlled models.

The cost of fiber-optic components is one major limitation facing Ukrainian manufacturers. Prices have skyrocketed in recent times, with increases of up to 10 times between 2025 and 2026. The situation reached its most critical point around March, before stabilizing somewhat since then.

However, the underlying issue remains that Ukraine relies heavily on Chinese supply chains for fiber-optic materials. This dependence affects not only availability but also pricing, as manufacturers must navigate global demand for these components. FPV drones are just one application of fiber-optic technology, with data centers and AI infrastructure driving up demand worldwide.

The growth of the global market for fiber-optic materials has a direct impact on Ukrainian drone manufacturers. They face challenges in securing reliable supplies and managing costs amidst rising prices and shortages. This situation is unlikely to change anytime soon, given the broad reach of the fiber-optic industry.

To mitigate these challenges, some Ukrainian manufacturers have started moving the spooling process in-house. By purchasing larger spools of fiber-optic material directly from China and then producing smaller drone-specific spools themselves, they gain more control over their finished products.

This shift does not address the fundamental issue of dependence on Chinese supply chains for raw materials but allows manufacturers to better manage their production processes. The long-term implications of this strategy remain unclear, as Ukrainian manufacturers continue to navigate the complexities of global fiber-optic markets.

Manufacturers in Ukraine are taking control of their fiber-optic supply chain by producing spools domestically.

This shift is driven by concerns over quality, as defects in imported finished spools can have serious consequences for drone operations.

If a fiber-optic spool has a defect, it can lead to the loss of the drone, mission, and target, making quality control a top priority.

In addition to fiber optic, media converters are another crucial component in this supply chain, with China also playing an important role as a supplier.

Ukrainian companies are now buying large quantities of raw fiber-optic material and producing smaller spools designed for FPV drones domestically.

This approach not only allows manufacturers to perform their own quality checks but also provides more control over the production process.

However, this shift towards domestic production is not uniform across the industry, with larger companies having the resources to invest in spooling equipment and testing capabilities.

The procurement process for fiber-optic materials has its complexities, with various factors influencing prices and availability. One such factor is the purchasing route, which can vary depending on the country and intermediary involved.

Despite these variations, China remains the primary source of the fiber-optic material in question. Ukrainian companies have encountered situations where suppliers were unable or unwilling to fulfill orders due to several reasons.

These include the manner in which the material is purchased, the supplier involved, and logistical considerations. Some Chinese manufacturers have reportedly informed Ukrainian buyers that they did not have the necessary materials available for them, citing their nationality as a reason.

In addition to availability and price, other supply-chain challenges exist beyond these concerns. Logistics plays a significant role in this context, with the material needing to pass through customs before reaching manufacturers in Ukraine.

Air raid alerts can disrupt this process, causing delays due to halted customs operations and transportation. Companies must factor these interruptions into their production planning, further complicating the procurement process.

Security considerations also pose a challenge for manufacturers involved in fiber-optic production. While specific cases cannot be disclosed due to security restrictions, the threat of attacks on manufacturing facilities is a pressing concern.

The lengthy transportation route from China to Ukraine adds another layer of complexity to the supply chain. Manufacturers must account for both time and logistics costs when transporting materials over such distances.

The challenges faced by drone manufacturers in Ukraine have led to a squeeze on their ability to produce high-quality fiber-optic spools. One crucial aspect is planning, which has become extremely important for these companies. This involves coordinating production and logistics to ensure that materials are available when needed.

In-house manufacturing capabilities also play a significant role in mitigating these challenges. Companies can better manage the quality of their products by having more control over the manufacturing process. Furthermore, if the fiber used is of high quality with fewer defects, more usable spools can be produced from a single large spool of material.

Producing fiber-optic spools requires specialized personnel who have received extensive training in the process. Unfortunately, there are no universities that specifically train individuals to manufacture these FPV fiber-optic spools. This means that companies must invest heavily in training their staff to acquire the necessary skills.

As a result, training itself becomes a significant cost factor for drone manufacturers in Ukraine. Not only does it consume valuable time and resources but also consumes fiber-optic material, further exacerbating the challenges faced by these companies.
