Ukraine’s fiber optic drones face higher costs as data centers buy more cable

In short: Ukraine’s makers of fiber optic drones are facing higher prices and tighter supply because the same cable is also being bought for AI data centers, and Russia is importing more of it from China.

What's going on

Fiber optic drones are connected to their human operators by a thin cable, instead of using radio signals. Think of it like flying a drone on a very long, lightweight “leash.” This makes them harder to jam, because there is no radio link to interfere with.

These drones have become common in Ukraine, and both Ukraine and Russia are making large numbers of them. Reporting cited by Ars Technica says the two countries have produced an estimated 50,000 fiber optic drones per month in recent years. Each one needs cable that is often treated as a one time use item in battle.

The problem is that optical fiber, the same material used for internet and data centers, is in high demand worldwide. Market researcher TrendForce expects a global shortfall of 111 million miles (180 million kilometers) of fiber in 2026. Ars reports that prices for some fiber used in drones rose roughly six to ten times from 2025 to 2026, according to Oleksiy, an R&D representative at Ukrainian drone maker BlueBird Tech.

China is the main source for this material. Ars also cites customs and media reports showing Russia has been able to import far more fiber optic cable from China than Ukraine, which adds pressure to Ukraine’s supply.

What to watch

Ukrainian manufacturers say they are adapting by doing more work at home, such as winding cable onto smaller spools themselves, instead of buying ready to use spools from China. This can improve quality control and sometimes reduce costs, but it does not remove the underlying dependence on global fiber supply.
