Ukraine Fiber Optic Spool Prices Jump More Than Eightfold As AI Data Center Demand Squeezes Drone Supply

A Ukrainian drone operator says his unit is now paying more than eight times what it used to for the fiber optic spools that feed their jam-proof FPV drones. Dimko Zhluktenko, co-founder of the Dzyga’s Paw charity fund and now serving with Ukraine’s Unmanned Systems Forces, said in a May 10 post on X that his unit used to buy 50-kilometer fiber optic spools for $300. Today, he said, “it’s easily $2,500.”

His figure lines up with what Western trade press, Asian fiber suppliers, and Corning’s own earnings have been reporting since late 2025. Global fiber optic prices are in a supply crunch driven by two colliding demand sources: AI data center buildouts consuming bend-insensitive fiber at industrial scale, and Russian and Ukrainian drone units burning through tens of millions of kilometers of the same fiber type every year.

Zhluktenko also said fiber-optic drone use on the battlefield, while still happening, is “not as much as it used to be.” That is a direct consequence of the price his unit and others now face.

The AI Data Center And FPV Drone Compete For The Same Fiber Type

The shared input is G.657.A2, a bend-insensitive single-mode fiber that can be wound tightly onto small spools without losing signal integrity, which makes it ideal both for high-density AI data center cabling and for the compact spools FPV drones unspool over 10 to 30 kilometers mid-flight. The same property the hyperscalers want is the same property a drone operator wants.

According to Light Reading, the price of standard single-mode G.652.D fiber rose 75 percent in January 2026 and now sits at its highest level in seven years. The China Electronic Components Industry Association reported that all four major Chinese fiber vendors are running at full capacity. Corning posted a 71 percent jump in Q4 net earnings for its optical division and signed a $6 billion fiber supply agreement with Meta, an amount equal to Corning’s entire optical revenue the prior year. CEO Wendell Weeks said in a January 28 CNBC interview that he expected demand to remain high throughout 2026.

The Kyiv Post, citing Russian outlet Vedomosti, reported that the wholesale price of a kilometer of Chinese-made fiber rose from 16 yuan ($2.33) in January 2025 to 40 yuan ($5.83) in January 2026. Spot prices in Western markets are higher. Suppliers in March 2026 were quoting G.657.A2 at $33 to $35 per kilometer, with weekly price revisions.

At $35 per kilometer, a 50-kilometer spool of bare fiber alone runs $1,750, before spooling, sheathing, packaging, import logistics, and wartime markup. Zhluktenko’s $2,500 figure for a delivered, ready-to-fly spool tracks with that math.

Russia And Ukraine Burn 50 Million Kilometers Of Fiber A Year

Kyiv Post analysis pegged combined Russian and Ukrainian fiber-optic drone consumption at 50 to 60 million kilometers in 2025, with Russia alone accounting for roughly 10 percent of global fiber output and sourcing almost entirely from China through intermediaries because Western sanctions cut off American, Italian, and Japanese supply. Ukraine relies on a mix of Chinese and Western imports.

This is not abstract supply chain stress. It is a measurable shift in unit cost for an entire category of weapon system. Ukrainian and Russian FPV strike drones using fiber tethers have become the working answer to electronic warfare jamming, and both sides have scaled production aggressively. DroneXL has covered the buildout from the first jamming-resistant fiber-optic combat drone Ukraine fielded in December 2024 to the integration of fiber-optic FPV launchers onto Ratel H ground robots reported in February 2026.

Ukraine passed laws through the Verkhovna Rada in June 2025 offering tax and customs incentives for domestic fiber cable production, but Ukraine does not manufacture the underlying optical fiber itself. The country imports the raw material and assembles the spools. That makes Ukrainian drone units price takers on the global fiber market, the same market Meta, Microsoft, and Google are bidding up.

Russian Strikes On A Fiber Factory Tightened Supply Further

Ukraine took the Russian end of the supply chain offline in spring 2025, when two Ukrainian drone raids on a Russian fiber-optic cable factory in April and May 2025 caused fires that halted production after flying roughly 1,400 kilometers through Russian airspace to reach the target. The Moscow Times reported the facility remained offline nearly a year later.

Russia compensated by importing more from China, which contributed to the price squeeze felt by Ukrainian buyers. Ukraine destroyed Russian fiber capacity and then competed with Russia for replacement Chinese supply, on a market already being consumed by AI hyperscalers.

DroneXL’s Take

DroneXL has covered fiber-optic FPV drones since Ukraine fielded the first jamming-resistant tethered combat drone in December 2024. The story arc has gone from battlefield curiosity to core procurement category in eighteen months. What Zhluktenko’s number adds is the cost story underneath that arc, told from the buyer’s side of the table.

An eightfold price increase on a consumable input is not a fluctuation. It is a structural problem. Ukrainian volunteer-funded units like the ones Dzyga’s Paw supplies are now competing for fiber capacity with companies whose AI capital expenditure budgets are measured in tens of billions of dollars. NVIDIA and Corning announced a partnership on May 6 that expands Corning’s U.S. optical connectivity capacity tenfold and U.S. fiber production capacity by more than 50 percent. That new capacity is aimed at AI hyperscalers, not drone units. Preform capacity, however, is the upstream constraint feeding all fiber types, so relief at the AI end could eventually ease pressure on bend-insensitive G.657.A2 supply for FPV drone spools.

The unanswered question is whether Ukraine’s June 2025 domestic incentive law has actually scaled finished-spool production fast enough to absorb any of this pressure. Watch Corning’s Q3 2026 earnings call and the company’s stated commissioning timeline for its new North Carolina and Texas plants for whether supply-side relief arrives before the front line adapts away from fiber entirely. Zhluktenko’s comment that fiber-optic drone use is already happening “not as much as it used to be” suggests the adaptation is already underway. The eightfold price hike is doing what Russian electronic warfare could not. It is pricing Ukraine out of its own counter to jamming.
