Fiber Optic Cable Costs Soar Due to War and AI Data Center Demand

Fiber-optic cable has become a critical component in modern warfare, enabling drone operations across vast distances while remaining immune to electronic jamming. Combatants from Ukraine to the Sahel are deploying quadcopters controlled via kilometer-long fiber-optic cables, which spool from tubes beneath the drones as they fly. This method provides a fast, clear, and jam-proof connection between operator and drone.

However, the technique that was once a cost-effective way to bypass enemy electronic warfare is now facing severe price hikes. The surge in demand from both military applications and data centers is driving up costs, making fiber-optic drone operations increasingly expensive.

Russia’s Fiber-Optic Drone Tactics and Ukraine’s Response

In 2023, Russia began deploying FPV drones controlled via fiber-optic cables, a tactic that initially caught Ukrainian forces off guard. The move led to heavy vehicle losses for Ukraine, but Kyiv quickly adopted the same strategy. Today, wheat fields across Ukraine are littered with discarded fiber-optic cable.

Dimko Zhluktenko, a Ukrainian soldier, highlighted the dramatic cost increase in a post on X (formerly Twitter) on May 10:

"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 a 50km spool for $300, now it's easily $2500. Just so you know."

The price of fiber-optic cable has risen steadily since 2023, nearly doubling in recent months. In January, Shanghai-based fiber-optic company Sun Telecom warned of a "fiber famine" in 2026. Last year, a kilometer of its G.652D fiber cable cost $2.20. By December 2025, the same length cost $3, and by January 2026, the price increased again to $4.10.

AI Data Centers Fueling Fiber-Optic Shortages

One of the primary drivers behind the rising costs is the insatiable demand for fiber-optic cable from data centers. As companies rush to build infrastructure for artificial intelligence (AI), the need for high-speed connectivity has surged. Wendell Weeks, CEO of fiber-optic cable manufacturer Corning, noted in an interview with CNBC:

"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."

Corning recently signed a $6 billion deal with Meta to supply fiber-optic cable, underscoring the scale of demand.

In January, North Carolina-based telecom company Brighspeed issued a warning on LinkedIn about "fiber-supply shortages." Two additional American internet service providers (ISPs) told Broadband Breakfast that they had experienced unexpected order cancellations, with some suppliers citing delays in delivery timelines.

Market Shifts and Future Outlook

The combination of military demand and AI-driven data center expansion has created a perfect storm for fiber-optic cable supply. As prices continue to climb, militaries and tech companies alike are reassessing their reliance on this once-affordable resource. The "fiber famine" predicted for 2026 could further disrupt industries dependent on high-speed connectivity, from drone warfare to cloud computing.
