TL;DR
The cost of fiber-optic cable is rapidly increasing due to heightened demand from military conflicts and data center expansion. Prices have nearly doubled in recent months, impacting supply and strategic deployments worldwide.
Fiber-optic cable prices have surged dramatically in 2026, driven by increased demand from both military conflicts in Ukraine, Iran, and Africa, and the expansion of data centers for AI infrastructure. The cost of a kilometer of fiber has nearly doubled over the past few months, impacting military and commercial supply chains.
Since 2023, the price of fiber-optic cable has increased significantly, with a Shanghai-based company, Sun Telecom, raising prices from $2.20 per kilometer in 2025 to $4.10 in early 2026. This escalation is largely attributed to heightened demand from military conflicts, where fiber-optic cables are used for FPV drones controlled via long fiber links, and from the rapid buildout of data centers supporting artificial intelligence and cloud computing. The demand from Ukraine and Russia alone consumes an estimated 50-60 million kilometers of fiber annually, mostly imported from China, which has also seen prices jump from $2.33 to $5.83 per kilometer within a year.
Military applications have historically used fiber-optic cables for stealthy, jam-proof drone control, but the rising costs are making such tactics less economically viable. Ukrainian soldiers reported in May 2026 that the cost of a 50 km spool has increased from $300 to approximately $2,500, complicating ongoing military operations. Meanwhile, global supply chains are strained; several U.S. ISPs have reported delays and cancellations of fiber orders, citing shortages and rising prices, according to trade sources.
Why It Matters
This surge in fiber-optic cable prices has broad implications for both military and commercial sectors. Militaries rely on fiber for stealth drone operations, and rising costs may limit their deployment or accelerate the shift to alternative technologies such as satellite communications like Starlink. For the tech industry, the cost escalation threatens to slow the expansion of data centers crucial for AI development, potentially delaying technological progress and increasing infrastructure costs globally.

Background
Since 2023, demand for fiber-optic cable has surged due to both military needs and the expansion of data centers supporting AI and cloud services. Countries involved in ongoing conflicts, including Ukraine, Russia, Iran, and regions in Africa, consume large quantities of fiber, predominantly imported from China. The destruction of Ukraine’s domestic fiber manufacturing facility by drones in 2025 further increased reliance on Chinese imports, pushing prices higher. Meanwhile, industry leaders like Corning’s CEO Wendell Weeks have warned of supply shortages as hyperscalers and telecom providers rush to meet their infrastructure needs.
“Fiber-optics is still happening at the battlefield, although not as much as it used to be. It’s extremely pricey now. We used to buy 50km spool for $300, now it’s easily $2500.”
— Dimko Zhluktenko, Ukrainian soldier
“Almost every phone call I get from my customers is trying to see, how do we get them more? I think next year the hyperscalers will be our biggest customers.”
— Wendell Weeks, CEO of Corning
“The drive toward the development and deploying at least partial autonomous control for drones to defeat electronic warfare jamming will accelerate as fiber optic FPVs become less available.”
— Roy Gardiner, OSINT analyst at Defense Tech

What Remains Unclear
It remains unclear how long the current price surge will last or whether alternative supply sources will emerge to stabilize costs. The full impact of these rising costs on military tactics and global supply chains is still unfolding, and future developments in fiber manufacturing or alternative technologies could alter the current trajectory.

Key Questions
Why are fiber-optic cable prices rising so rapidly?
The increase is primarily driven by high demand from military conflicts requiring stealth drone control and the expansion of data centers supporting AI, combined with supply chain constraints and rising raw material costs.
How does this impact military operations?
Rising costs limit the deployment of fiber-optic drones and may lead militaries to seek alternative technologies or develop autonomous systems to avoid reliance on expensive cables.
Will the supply shortage affect global internet infrastructure?
Potentially, as data centers and telecom providers face higher costs and delays, which could slow the expansion of internet infrastructure and increase operational expenses.
Are there alternatives to fiber-optic cables for drone control?
Yes, satellite-based systems like Starlink are being used, but they are currently more expensive per operation and have limitations in range and latency compared to fiber-optic links.
What is the outlook for fiber prices beyond 2026?
It is uncertain; prices could stabilize if supply chains adapt or new manufacturing sources emerge, but current trends suggest continued upward pressure in the near term.
