# AI data centres are bidding up the fibre that guides Ukraine's drones
> A 50km spool that cost $300 now runs ~$2,500 — the same bend-insensitive fibre feeds both FPV cables and hyperscaler racks

## Summary

The bend-insensitive optical fibre that [Ukraine](/pt/entity/ukraine) and [Russia](/pt/entity/russia) unspool to guide
jam-proof [Fpv Drones](/pt/entity/fpv-drones) is now in a global supply crunch — and the squeeze comes from
[Data Centers](/pt/entity/data-centers), not the war. G.657.A2 single-mode fibre winds tightly onto small spools
without signal loss, which makes it ideal both for compact FPV reels and for high-density
AI-rack cabling that Meta, Microsoft and Google are buying at industrial scale. One
Ukrainian operator's 50km spool jumped from ~$300 to ~$2,500. Ukraine imports the raw
fibre — it assembles spools but does not draw the glass — leaving its 35+ assemblers as
price-takers on the same spot market as the hyperscalers. Fibre-guided FPVs defeat
[Electronic Warfare](/pt/entity/electronic-warfare), so demand is structural, not a spike. The [A mudança silenciosa](/pt/head/the-quiet-shift): a
compute boom is now a wartime input cost.

## By the numbers

- ~8x — rise in a 50km fibre-spool price (~$300 to ~$2,500) reported by Ukrainian operators.
- $33–35/km — March 2026 spot quotes for bare G.657.A2 fibre, revised weekly.
- 50,000+ — fibre-optic drones Ukraine builds per month across 35+ assemblers; Russia at least matches it.
- ~70% — share of 2026 state drone buys Ukraine aims to route via DOT-Chain Defence.
- 30–50% — fibre-optic share of FPVs in some Russian front-line units by early 2026.

## Why it matters

Fibre-optic FPVs are the one drone class that EW cannot defeat, so both armies must keep
buying. But the input is a dual-use commodity now dominated by AI buildout demand. A war
input has become hostage to a Silicon Valley capex cycle — and Ukraine, lacking domestic
fibre drawing, has the least leverage over the price.

## What to watch

- Whether Ukraine's June-2025 tax/customs incentives produce any domestic fibre-drawing capacity.
- DOT-Chain Defence procurement volumes and whether state budgets absorb the higher unit cost.
- Hyperscaler fibre orders through 2026–27 and any easing as new drawing capacity comes online.

## Regional takes (batched by bias / lens)

### Ukrainian front-line production reporting
- **Ukrainska Pravda** (Ukraine, uk) — Investigates why Ukraine still trails Russia on fibre-optic FPV output despite 35+ assemblers: it imports raw fibre, lacks domestic drawing capacity, and competes on a global spot market. Maps the DOT-Chain Defence procurement push aiming to route ~70% of state drone buys in 2026.

### Drone-industry trade analysis
- **DroneXL** (United States, en) — Documents the eightfold spool price jump and pins the structural cause: G.657.A2 bend-insensitive single-mode fibre is the same product Meta, Microsoft and Google buy for high-density AI data-centre cabling. Ukrainian and Russian units burning tens of millions of km a year are price-takers.
