The global market for G657A2 bare optical fiber has entered uncharted territory. If you are sourcing drone optical fiber or fiber optic spool products for FPV applications, you have likely experienced soaring prices, extended lead times, and supply uncertainty.
This article analyzes current demand trends—with a focus on Ukraine, Poland, and Russia—examines the production capacity of major Chinese manufacturers, provides a September 2026 price outlook, and offers practical procurement advice from GL FIBER.
Regional Demand Analysis: Ukraine, Poland, and Russia
Russia: The 100% Import Dependency
The most dramatic demand shift comes from Russia. Following the shutdown of its domestic optical fiber plant (Optovolokonnye Sistemy in Saransk) in mid-2025, Russia became entirely dependent on imported fiber, primarily from China . This plant previously supplied approximately 30-40% of Russia's domestic fiber demand, producing about 4 million kilometers annually for around 20 local cable manufacturers .
The impact has been profound:
- Russia's share of global fiber consumption surged from less than 1% to an estimated 10.5% in 2025, with purchases reaching nearly 60 million kilometers .
- Chinese suppliers increased prices for the Russian market by 2.5 to 4 times since early 2025 .
- Russia's 2026 drone production is expected to reach 4 to 5 million units, generating massive demand for 50.4km optical fiber spools .
Ukraine: Government-Driven Procurement
Ukraine has also significantly increased its procurement of FPV drones, with fiber-optic models receiving priority funding. Key market data includes:
- Ukraine allocated over UAH 44 billion for FPV drone procurement in 2025 .
- The government enacted tax incentives, including import duty and VAT exemptions, for domestic drone manufacturers supplying defense forces .
- Combined Russian and Ukrainian fiber-optic drone consumption reached 50–60 million kilometers in 2025 .
Poland and Other European Markets
Poland and other European nations are increasing UAV procurement, driving demand for bare optical fiber spools. The fiber optic guided drones market itself is projected to reach approximately $2.3 billion in 2026** and grow to **$4.5 billion by 2036 .
Summary: Demand Trends by Region
- Region Key Driver Estimated 2026 Demand Impact
- Russia 100% import dependency for drones ~50-60 million km (combined with Ukraine)
- Ukraine Government procurement, tax incentives Part of the 50-60 million km total
- Poland & EU Growing UAV programs, defense procurement Increasing
- Global AI Data center build-outs ~100 million core-km in 2026
Major Chinese Manufacturers: Production Capacity
China's fiber optic industry is dominated by four major players, often referred to as the "Big Four" :
Manufacturer Estimated Annual Production Capacity Preform Self-Sufficiency Key Notes
YOFC~140 million core-km Yes (global leader) Largest globally; orders booked through Q1 2027
Hengtong ~110 million core-km ~90%+ Strong export focus
ZTT ~70 million core-km 80-100% Diversified portfolio
FiberHome ~66 million core-km 80-100% State-backed, "East-to-West" projects
Current Capacity Reality:
- The top four manufacturers' preform production capacity is operating at near 100% utilization.
- According to CRU, China's preform capacity utilization reached 84.3% in 2026, with effective capacity near full load.
- Even under extreme conditions, capacity can be expanded by only 10-15% through process optimization alone.
The Capacity Squeeze Effect
Manufacturers are prioritizing higher-margin G.657.A2 fiber, which requires 10-15% more production time per kilometer than standard G.652.D due to more complex processes . This structural shift has:
- Reduced effective output of G.657.A2 despite high demand
- Created a supply vacuum for standard grades
- Widened the global supply-demand gap to an estimated 0.35–0.82 billion core-km through 2027
September 2026 Price Outlook for G657A2 Fiber
Current Market Pricing
As of August 2026, G.657.A2 fiber trades at approximately $27–33/km (210–240 RMB) . This represents a 650% increase from early 2025 levels of approximately 32 RMB/km .
September 2026 Forecast
Industry analysts project the following for September 2026 :
Timeframe Expected Price Range Key Drivers
September 2026 $28–35/km Continued tight supply; Q3 procurement peak
Late 2026 $30–37/km AI data center demand; year-end procurement
2027 $32–40/km Supply-demand gap widening; new capacity uncertain
Key Factors Supporting September Prices
AI Data Center Demand: NVIDIA's GB300 GPU is expected to begin mass production in Q4 2026, driving a new wave of data center fiber demand . Global AI fiber demand is projected to reach ~200 million core-km in 2026 .
- Preform Capacity Constraints: The expansion cycle for optical preforms is 18–24 months, meaning new capacity approved today will not come online until late 2027 at the earliest .
- Military Drone Demand: Drone-related fiber demand is projected to reach 80 million core-km in 2026, with continued consumption from military applications .
- Q3 Procurement Season: Telecom operators typically increase procurement in Q3, adding demand pressure.
- Note: Some analysts suggest that prices may stabilize in the $28–35/km range in September as buyers adapt to the new pricing reality, but significant declines are unlikely in 2026 .
Procurement Advice: How to Buy G657A2 Fiber in 2026
1. The A1 vs. A2 Trap
G.657.A1 and G.657.A2 look nearly identical, but their performance differs significantly :
- Parameter G.657.A1 (Substandard) G.657.A2 (Genuine)
- Min. Bend Radius 10 mm 7.5 mm
- Macrobending Loss (1550nm, 15mm radius) ≤ 0.25 dB ≤ 0.03 dB
- Suitability for FPV Drones Fails in dynamic deployment Engineered for drones
- The risk: Buying A1 labeled as A2 means the fiber exceeds its bend limit during spooling or deployment. Signal attenuation spikes—and the drone loses connection mid-flight .
2. Verify What You Are Buying
- Demand batch-specific macrobending loss test reports – Do not accept "typical values" .
- Verify coating diameter – 0.25mm (245 ± 10 μm) is standard for drone applications .
- Check ITU-T compliance – Genuine G.657.A2 comes with ITU-T G.657.A2 certification matching your shipment's batch number.
3. Watch for Warning Signs
- Pricing significantly below $27/km – Likely A1 or substandard fiber.
- "No documentation available" – Legitimate manufacturers provide full traceability.
- 100% upfront payment to unknown suppliers – High fraud risk.
- Inability to arrange factory visits or video calls – Real manufacturers welcome transparency .
4. Secure Your Supply Chain Now
- With orders booked through Q1 2027 at major manufacturers , the time to secure your fiber optic spool needs is now:
- Lock in long-term capacity – Long-term contracts are the only reliable way to secure supply.
- Partner with source factories – GL FIBER controls its own preform and drawing capacity.
- Plan for extended lead times – Current lead times have extended from 8-12 weeks to 20+ weeks.
