If you are sourcing g657a2 bare fiber, g657a2 drone fiber, or fpv drone fiber for drone applications, you have likely noticed something frustrating: prices are rising again, and 50.4km optical fiber spool products are becoming increasingly difficult to secure.
The reason is not what most buyers expect. It is not simply AI data centers or drone demand. It is a massive domestic carrier tender in China that is forcing manufacturers to redirect production capacity—leaving international buyers competing for a shrinking pool of available G657A2 fiber. This article explains what is happening, provides current pricing data, and offers practical procurement advice from GL FIBER.
📊 What Is Happening in the Chinese Market?
The China Mobile Tender: 70 Billion RMB
China Mobile, the world‘s largest telecom operator by subscribers, has launched its 2026-2027 ordinary optical cable centralized procurement—a tender worth approximately 7.1 billion RMB (about $980 million).
Key details:
Total procurement volume: 2,161,800 cable kilometers (approximately 69.22 million core-km)
Winning bidders: 18 companies, with the top four (YOFC, ZTT, Hengtong, FiberHome) collectively holding 38.81% share
Price revision: The maximum bid limit was raised by 8.5% after the first round failed due to prices being too low
Final average price: 102.56 RMB per core-km (excluding tax)—a 90.5% increase from the previous round
Why This Matters for G657A2?
This is not just about standard G.652.D cable. Manufacturers must dedicate production capacity to fulfill this massive order. Preform—the upstream raw material for all optical fiber—is already running at 84.3% utilization in China. When major manufacturers commit preform capacity to carrier-grade G.652.D orders, less preform is available for specialty fibers like G657A2.
The result: G657A2 production is being squeezed from both sides—demand remains high, but preform allocation is shifting toward carrier tenders.
📈 Current Price Trends: G657A2 Is Climbing Again
Year-Over-Year Price Surge
G657A2 fiber prices have experienced an extraordinary increase:
Timeframe
G657A2 Price (RMB/core-km)
Price (USD/km approx.)
Change
-
Early 2025 32 RMB ~$4.50 Baseline
-
Mid-2026 240 RMB ~$33 +650%
-
September 2026 210-220 RMB $27-29 Continuing upward pressure
Current Market Reality
According to industry data from September 2026:
-
G.657.A2 fiber has risen from 32 RMB to 240 RMB per core-km in one year—a 650% increase
-
50.4km spool availability has become particularly tight as international buyers compete for limited export allocation
-
Major manufacturers’ orders are booked through Q1 2027
Why Prices Are Rising Again?
Three factors are converging:
1. Carrier Tender Capacity Absorption
The China Mobile tender is absorbing significant preform and drawing capacity from major manufacturers. Even though the tender volume decreased 30% year-over-year (from 98.84 million to 69.22 million core-km), the price increase of 90.5% signals that supply is genuinely tight.
2. Structural Shift to High-Value Fiber
Manufacturers are prioritizing higher-margin products. G657A2 production requires 10-15% more time per kilometer than standard G.652.D because of more complex processes. When preform is scarce, factories allocate it to the highest-value orders.
3. International Demand Remains Strong
Russia and Poland are now the largest export markets for Chinese fiber, each exceeding $380 million in the first half of 2026. Ukraine‘s drone manufacturers remain heavily dependent on Chinese imports, with G657A2 being the most in-demand specification.
🏭 The 50.4km Spool Shortage: Why It Matters?
The 50.4km optical fiber spool has become the preferred packaging format for FPV drone applications. Why?
Operational efficiency: Longer spools mean fewer reel changes during missions
Cost efficiency: Fewer connectors, less waste
Logistics optimization: Fewer spools to ship and handle
But 50.4km spools require more fiber per unit—and when fiber is scarce, longer spools are the first to be constrained. International buyers report that 50.4km spools are now the hardest format to source, with lead times extending beyond 20 weeks.
🛒 Procurement Advice: How to Buy G657A2 Fiber in This Market?
1. Understand the Price Floor
When legitimate manufacturers are producing G657A2 at 240-260 RMB/core-km ($33-36/km), offers significantly below this range should raise immediate red flags.
What to watch for:
-
If a supplier quotes G657A2 at $20-25/km, you are almost certainly being offered G.657.A1 or substandard fiber
-
The performance difference matters: A1 supports a 10mm bend radius, while A2 supports 7.5mm—critical for drone deployment
2. Verify Before You Buy
✅ Demand batch-specific macrobending loss test reports – Genuine G657A2 must demonstrate ≤0.03 dB loss at 1550nm with a 15mm bend radius (10 turns)
✅ Check ITU-T compliance certificates – Match batch numbers to your shipment
✅ Inspect coating diameter – 0.25mm (245±10 μm) is standard for drone applications
✅ Request spool winding video – Verify professional tension control to prevent fiber damage during deployment
3. Secure 50.4km Spools Early
If your application requires 50.4km optical fiber spool format:
-
Place orders well in advance—do not wait for inventory to become available
-
Consider 25.2km spools as an alternative if 50.4km is unavailable
-
Work with suppliers who have direct factory allocation, not traders who compete for leftover capacity
4. Partner with Source Factories
In a supply-constrained market, traders cannot guarantee allocation. A source factory that controls its own preform and drawing capacity provides:
-
Priority allocation for direct clients
-
Price stability through factory-direct relationships
-
Quality assurance with full traceability
