Over the past few months, the global market for G.652.D optical fiber has undergone a rapid shift.
Prices that remained historically low between 2022 and 2025 have started to rise sharply in 2026. In some spot markets, fiber prices have already reached 9–13 USD per fiber kilometer (fkm) — several times higher than levels seen just two years ago.
More importantly, this is no longer just a discussion about raw material costs.
Real-world procurement cases show that telecom operators and network projects are already experiencing the effects of this price shift.
Global G.652.D Fiber Price Trend
Recent market observations suggest a clear upward trajectory in fiber pricing.
Approximate price levels (USD / fkm):
- 2022–2024: 2–3 USD
- Dec 2025: 3–4 USD
- Jan 2026: 5–7 USD
- Spot market 2026: 9–13+ USD
This represents a 70–120% increase within only a few months.
Several structural factors are driving this change:
- Rapid expansion of AI data centers requiring massive optical interconnection capacity
- Limited global preform production capacity, with expansion cycles typically exceeding two years
- Some manufacturers prioritizing G.657.A2 fiber for dense data center environments
- The gradual end of the historically low price cycle observed between 2022 and 2025
These dynamics are reshaping the economics of fiber supply across the industry.
When Fiber Prices Rise: A Supply Chain Ripple Effect
The impact of rising fiber prices does not stop at fiber manufacturers.
Instead, it spreads through the entire telecom supply chain:
Preform manufacturers → Fiber producers → Cable manufacturers → System integrators → Telecom operators
As upstream costs increase, downstream participants eventually face higher procurement costs or supply limitations.
Two recent procurement cases in China illustrate how this ripple effect is already influencing telecom projects.
Case Study 1: Guangdong Telecom Tender Cancellation
A major optical cable procurement project from Guangdong Telecom recently failed after reopening the bidding process.
The operator had already raised the maximum bid price by approximately 45%, yet the tender still failed because fewer than three qualified bidders participated.
Industry sources indicate the primary reason was market cost pressure.
Since late 2025, the price of G.652.D bare fiber has increased significantly. The original procurement price ceiling was reportedly below the actual production cost, making it economically unfeasible for cable manufacturers to submit bids.
In such situations, suppliers may simply withdraw from the tender rather than accept loss-making contracts.
Case Study 2: Chongqing Telecom Emergency Procurement
Another example highlights how operators are adapting to rising cable prices.
A Chongqing Telecom emergency cable procurement project required three bidding rounds before completion.
The maximum bid prices evolved as follows:
- First round: 218 RMB per cable km — no bidders
- Second round: 258 RMB per cable km — no bidders
- Third round: 350 RMB per cable km — successful procurement
Despite the higher unit price, the total project budget remained fixed at approximately 1.75 million RMB (excluding tax).
As a result, the operator ultimately reduced the procurement quantity to stay within the approved budget.
This case demonstrates a key reality: when unit prices rise, project scale often adjusts accordingly.
Implications for Telecom Network Deployment
These developments suggest several potential implications for telecom operators and network planners.
1. Greater Procurement Uncertainty
Price volatility in upstream materials can make long-term project budgeting more complex.
2. Supply Planning Becomes Critical
Spot market availability may become more limited, making early procurement planning increasingly important.
3. Cost Pressure on Network Expansion
Large-scale access network and FTTH deployments may experience unexpected cost adjustments if fiber prices remain elevated.
Looking Ahead
Global demand for digital infrastructure continues to grow rapidly.
From AI computing clusters to FTTH broadband expansion, optical fiber remains the fundamental layer supporting modern connectivity.
As the market adjusts to new supply-demand dynamics, stakeholders across the telecom ecosystem may need to rethink procurement strategies, supplier partnerships, and project planning horizons.
Because when fiber prices rise, the effects rarely stay upstream — they eventually reach the entire telecom network supply chain.
