Reported by TrendForce Press Center on October 19, 2026. Summarized and analyzed by XAIPART Editorial.
What happened
TrendForce expects AI data centers, interconnects and high-capacity backbone deployments to drive a global optical fiber supply shortfall of 180 million fiber-kilometers in 2026.S1 Spot prices for finished optical fiber products are projected to reach 2.8–5 times their 2025 levels or higher as supply tightens.S1 Telecom operators are responding by shifting from short-term purchasing toward long-term supply agreements.S1
Global optical fiber capacity utilization reached 92% in 2026, while inventory declined from four months in 2024 to one month.S1 Some leading suppliers are booked through the first quarter of 2027, and preform capacity additions typically require 18–24 months for equipment installation and process establishment.S1 TrendForce projects demand of 577 million fiber-kilometers in 2026, with data centers representing roughly 18–20% of the total; that share is projected to reach 30–35% in 2027.S1
| Metric | Reported value | Source |
|---|---|---|
| 2026 supply shortfall | 180 million fiber-kilometers | S1 |
| 2026 capacity utilization | 92% | S1 |
| 2026 demand | 577 million fiber-kilometers | S1 |
| Inventory | One month, down from four months in 2024 | S1 |
| Preform expansion cycle | 18–24 months | S1 |
Bend-insensitive fiber used inside data centers is expected to average more than five times its 2025 price in 2026; AI backbone fiber is projected at approximately 2.8 times, and mainstream telecom fiber at around 3.7 times.S1 Verizon and Corning signed a multi-year agreement in September 2026 covering 129 million fiber-kilometers for delivery from 2027 to 2032.S1
Background timeline
XAIPART take
Technical impact
XAIPART analysis: Procurement teams should check whether fiber specifications, especially bend-insensitive and AI backbone grades, are tied to spot-market availability rather than stable contracted pricing. Qualification work should account for connectivity, cabling and installation constraints because a fiber purchase may affect the wider data-center interconnect design, not only the cable itself.
XAIPART analysis: The reported 92% utilization and one-month inventory leave little room for substitutions based only on nominal fiber type. Engineers should verify attenuation, bend performance, connector compatibility and delivery requirements with suppliers before treating an alternative grade as equivalent.
Market impact
XAIPART analysis: The combination of projected price multiples, limited inventory and an 18–24 month capacity-expansion cycle points to procurement exposure extending beyond a single quarter. Buyers should compare total landed cost and contractual flexibility rather than rely on a short-term spot quotation.
XAIPART analysis: Long-term agreements may improve allocation visibility for large deployments, but they can also lock in volume before a project’s final build schedule is certain. The source did not disclose the contract prices attached to the Verizon-Corning agreement, so its cost effect cannot be calculated.
Action
XAIPART analysis: Map current and planned fiber demand, separate data-center interconnect, AI backbone and mainstream telecom requirements, and request lead-time and allocation data for each grade. Review safety stock and supplier diversity before committing to a long-term agreement.
XAIPART analysis: For active designs, preserve approved alternatives and confirm that any substitute preserves installation geometry, bend radius, attenuation and connector requirements. Record the source did not disclose available cable lengths, regional allocation or exact supplier lead times.
XAIPART Forecast
XAIPART analysis: XAIPART expects optical fiber capacity utilization for TrendForce’s market to remain at or above 92% through the first quarter of 2027 if supplier bookings and the 18–24 month preform expansion cycle persist; this forecast would be wrong if utilization falls below 92% or announced capacity enters production sooner than reported.
XAIPART analysisFacts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. Uncertainty remains because this is a single-source projection; the source did not disclose exact supplier lead times, contract pricing or regional availability.
