When NVIDIA commits $3.2 billion to lock in Corning’s capacity, when Meta signs a $6 billion mega-deal with Corning, and when G.654.E fiber prices surge sixfold in a single year, the message is unmistakable. North American fiber demand is projected to grow by 22%–25%, yet supply can only expand by 12%–19%. Lead times for bulk orders now exceed 20 weeks, while smaller batches face delays of up to a year. These signals point to a singular reality: fiber optics, once considered a traditional "glass strand," is rapidly transforming into the most scarce strategic resource of the AI computing era.

In the fiber optic supply chain, optical preforms (preforms) represent the segment with the highest technological barriers and the greatest difficulty in capacity expansion. They directly dictate effective supply. Preform manufacturing relies on high-purity quartz glass, silicon tetrachloride, and germanium tetrachloride, alongside highly complex preparation processes (such as MOCVD and PCVD). This demands extreme precision in equipment and pristine cleanroom environments.

Crucially, preform expansion cycles stretch from 18 to 24 months—far longer than the mere months required for downstream fiber drawing and cable manufacturing. Consequently, once a supply-demand gap emerges, it is virtually impossible to fill through rapid expansion in the short term.

According to CRU data, global fiber production reached 652 million fiber-kilometers (fkm) in 2025, a year-on-year growth of 13.76%, marking a recent high. Regionally, Asia-Pacific and North America dominate global supply, with Chinese manufacturers holding approximately 60% of the market share. Overseas supply is led by Corning, Furukawa, Sumitomo, Fujikura, and Prysmian.

China maintains its core position as the world's primary supplier, leveraging a closed-loop industrial chain and scale-cost advantages. In 2025, China accounted for 59% of global preform output, 57% of fiber production, and 47% of cable production. Industry leaders like YOFC, Hengtong, ZTT, and FiberHome boast combined preform capacities of roughly 11,000 tons (translating to about 380 million fkm). Their core competitiveness stems from full-process preform preparation technology, large-scale manufacturing, industrial clustering, and global expansion capabilities.

The United States, as the birthplace of fiber technology, retains distinct advantages in core segments. In 2025, U.S. preform and fiber outputs accounted for roughly 15% and 12% globally, respectively. Corning, which invented the first low-loss communication fiber in 1970, masters core OVD preform processes and stands as the absolute leader in high-end specialty fibers, submarine cables, and data center high-speed fibers.

Japan possesses profound industrial foundations. Major players like Sumitomo Electric, Furukawa Electric, Fujikura, and Shin-Etsu Chemical dominate high-purity quartz materials and VAD preform processes, leading the high-end market with ultra-low-loss and bend-insensitive products.

Currently, top global preform manufacturers operate at near-maximum capacity. Overseas players like Fujikura and Furukawa have reached 100% utilization and face dual bottlenecks in preform and fiber expansion, prompting some to begin sourcing fiber directly from Chinese manufacturers. Having learned harsh lessons from past price wars, companies are extremely cautious about expanding capacity. The painful memory of "blind expansion followed by price crashes" has prevented major players from announcing massive new capacity plans during this early recovery phase.

AIinvest estimates that generative AI-driven data centers require over 10 times the fiber volume of traditional cloud infrastructure. CRU data reveals that global data center fiber demand grew by approximately 75.9% YoY in 2025, serving as the core engine pulling overall demand.

However, the supply side lags significantly behind. Rebio Group projects that in 2026, North American fiber demand will grow by 22%–25%, while supply will only increase by 12%–19%, further widening the deficit.

Global fiber prices have responded with surges. According to Huatai Securities, G.652.D single-mode fiber prices jumped from around RMB 18/fkm in early 2025 to RMB 85–120/fkm by March 2026—a nearly 650% increase. G.657.A2 single-mode fiber climbed from RMB 30/fkm to RMB 210–230/fkm, up about 557%. European markets are equally hot, with G.652.D bare fiber reaching €7.94/fkm in March 2026, up 136% MoM and 159% YoY.

Bulk buyers now face lead times exceeding 20 weeks, with small orders taking up to a year. This "pay-before-shipment" seller’s market is an unprecedented sight in the past decade.

To navigate these extended lead times and secure stable allocations, global buyers are increasingly turning to agile partners like NEW LIGHT OPTICS TECHNOLOGY LIMITED. We specialize in bridging the gap between international demand and top-tier manufacturing capacity. Reach out to our team at 13534063703 to discuss your project requirements.

Facing robust demand, Meta and NVIDIA have taken decisive action. In January 2026, Meta signed a multi-year agreement worth up to $6 billion with Corning for its data centers. Shortly after, in May 2026, NVIDIA announced an investment of up to $3.2 billion in Corning to build three new U.S. factories, aiming to boost optical connectivity manufacturing by 10x and fiber capacity by over 50%. This marks a structural shift from passive matching to active supply chain locking by chip giants.

The industry is evolving from standard single-mode to specialty fibers, and from solid-core to hollow-core architectures. This technological race is reshaping competitive dynamics.

G.654.E: Ultra-Low-Loss Fiber Becomes an AI Imperative
G.654.E ultra-low-loss, large-effective-area fiber is the preferred choice for current AI data centers. With typical attenuation ≤0.14dB/km at 1550nm (30% lower than standard G.652.D) and a larger effective area, it significantly enhances OSNR and transmission distance. Chinese manufacturers hold a dominant advantage here, with YOFC commanding 80%–90% market share. Domestic G.654.E costs merely 1/5 to 1/6 of overseas alternatives, maintaining a 20%–30% price advantage even at premium selling prices of RMB 240–260/fkm. Delivery takes under a month domestically, compared to over six months overseas.

Multimode Fiber: The Backbone of Internal Data Center Connectivity
For intra-data center connections (0–2km), OM4/OM5 multimode fibers dominate. As optical modules upgrade to 800G/1.6T, short-reach links heavily utilize multimode fibers. OM5, designed for SWDM, boosts capacity via multiple wavelengths. It is estimated that 4 million 800G optical modules will drive billions in multimode demand, with OM5’s share rising from 18% to 43% by 2030.

Hollow-Core Fiber: A Revolutionary Next-Gen Technology
Hollow-core fiber (HCF), boasting ultra-low latency, loss, and nonlinearity, is hailed as the next-gen transmission medium. By using air instead of glass, it reduces latency by over 30% (~1.5µs/km), critical for distributed AI training. Microsoft plans to deploy 15,000 km of HCF within 24 months. Commercially, YOFC has achieved kilometer-level mass production with record-low attenuation of 0.05dB/km, though pricing remains steep at ~RMB 35,000/fkm.

In the short term (1–2 years), high prosperity will persist due to preform expansion constraints. UBS forecasts 2026 fiber demand to grow 20%, with data center and drone fiber增速 at 70%–80%.

Mid-term (3–5 years), AI infrastructure continuity will dictate cycle length. CRU predicts 2027 global demand will hit 880 million fkm, with AI-driven data center demand jumping from <5% in 2024 to 35% in 2027. Corning expects Scale-Up demands to be 2–3x current enterprise networking volumes.

Long-term risks lie in technological uncertainties. CPO could alter module-to-fiber ratios, while low-cost HCF might reshape competition. However, through 2026–2027, traditional fiber dominance remains unshaken.

The feared "rush-in-and-overcapacity" scenario is unlikely to repeat, supported by three factors: traumatic memories of 2019 price collapses, long preform expansion cycles deterring new entrants, and high technical barriers for advanced fibers.

For investors and buyers alike, industry leaders are entering a window of earnings and valuation double-ups. Success in 2026 hinges not on having the largest capacity, but on possessing the hardest technology, sharpest layout, and fastest response.
