It is a critical upstream material whose glass composition, doping concentration, refractive-index profile, geometry, and longitudinal uniformity determine attenuation, mode-field diameter, macrobending loss, optical consistency, drawing yield, and long-term reliability. ITU-T Category A fibers remain compatible with the G.652.D system while providing reduced macrobending loss. G.657.A2 has more stringent bend-performance requirements than G.657.A1 and is suitable for access, transport, in-building, and data-center networks where compact fiber management and dense cabling are required. G.657.A2 is a fiber-performance category rather than a general quality grade for preforms. Fiber drawn from G.657.A2 preforms is used in AI data-center cabling, rack and distribution-frame interconnection, FTTH, building networks, patch cords, pigtails, and other space-constrained optical systems. Compared with conventional G.652.D fiber, it provides greater installation tolerance and lower loss under bending, coiling, and dense routing conditions. 1.2 Global Market Size and Growth Outlook The global G.657.A2 optical fiber preform market was valued at approximately US$1.45 billion in 2025, is estimated at about US$1.66 billion in 2026, and is expected to reach approximately US$3.50 billion by 2032, representing a CAGR of around 13.5% during 2026–2032. Global shipments in 2025 were approximately 8,653.84 tons, with an average price of about US$167,000 per ton and a manufacturing gross margin of approximately 42%. The market scope mainly covers high-purity silica preforms, core rods, overclad tubes, and integrated preforms used to draw G.657.A2 bend-insensitive single-mode fiber. FTTH and in-building networks remain the established demand base, while AI data centers, GPU clusters, optical-module interconnection, and dense rack cabling are becoming the major incremental markets. Global data-center fiber demand is expected to reach approximately 91.6 million fiber-km in 2026 and about 128 million fiber-km by 2030, with AI-related demand exceeding 80 million fiber-km. The current ITU-T G.657 recommendation explicitly identifies data centers as an application for Category A bend-insensitive fibers. Preform capacity expansion requires deposition, consolidation, glass-processing, and drawing equipment, together with extensive process ramp-up and customer qualification. Short-term supply elasticity is limited by raw-material purity, deposition efficiency, dopant uniformity, refractive-index control, and fiber-drawing yield. Equivalent fiber-kilometer quotations and per-ton preform prices are different measurement systems and should not be directly converted. 1.3 Competitive Landscape and Representative Companies The market favors vertically integrated manufacturers with capabilities across preforms, optical fiber, cable, and connectivity products. Preform manufacturing is more capital- and technology-intensive than downstream cable processing and therefore has a relatively concentrated supply structure. Representative international companies include Corning, Sumitomo Electric, Fujikura, Prysmian, Furukawa Electric, and Sterlite Technologies Limited. Representative Chinese companies include YOFC, Hengtong Group, ZTT Group, Wuhan Fenghuo Ruituo Technology, Zhejiang Fuchunjiang Photoelectric Technology, Far East Smart Energy, Tongding Interconnection, and Jiangsu Sterlite Tongguang Optical Fiber. Corning operates an integrated process from high-purity raw materials and OVD deposition through consolidation and fiber drawing. Sumitomo Electric has developed VAD into a mass-production preform process and has established integrated production from preform fabrication to drawing and coloring. Competition increasingly centers on captive preform capacity, refractive-index-profile stability, macrobending consistency, deposition rates, drawable length per preform, drawing yield, customer qualification, and volume delivery. Suppliers with high-purity glass technology, proprietary deposition equipment, internal drawing capability, and data-center customer access are positioned to achieve stronger supply stability and pricing power. 1.4 Product Segmentation and Application Structure By preform diameter, the market can be divided into 120–150 mm, 151–250 mm, and 300 mm and above. Smaller preforms offer more flexible production scheduling, while medium and large preforms improve drawable length and manufacturing efficiency. Large-diameter products require more precise deposition uniformity, consolidation, and internal-defect control. By manufacturing process, the principal routes are OVD, VAD, PCVD, and other hybrid processes. OVD is suited to high-volume and large-diameter manufacturing; VAD provides continuous axial deposition and strong impurity control; PCVD enables precise control of complex refractive-index profiles. Corning publicly describes its OVD process, while Sumitomo Electric has industrialized VAD technology. A simple step-index versus matched-cladding classification is not recommended as the primary segmentation. Bend-insensitive designs may use trench-assisted, modified-cladding, and other optimized structures, while ITU-T specifies final fiber performance rather than mandating a specific refractive-index design. The recommended application segmentation is data centers, FTTH and building networks, telecom access and transport networks, and other specialized communications. UAV fiber communication is a niche specialized application and is better included under Others. 1.5 Regional Landscape and Market Opportunities China is a major global manufacturing and consumption base for preforms, optical fiber, and cable, supported by an integrated supply chain covering high-purity chemicals, deposition equipment, preforms, drawing, and cable manufacturing. AI infrastructure, computing clusters, broadband upgrades, and FTTH replacement demand provide a strong growth foundation. North America is a leading demand center for AI data centers, cloud computing, and high-speed interconnection. Europe benefits from data-center investment, carrier fiberization, and building-network upgrades. Japan maintains strong capabilities in VAD processing, precision doping, low-loss fiber, and high-consistency drawing. Sumitomo Electric's official materials show that VAD has been developed from an R&D technology into a mass-production preform process, while Corning operates optical-fiber facilities across several major regions. Future regional opportunities will be concentrated in high-end preform expansion in China, AI data-center clusters in North America, dense-network upgrades in Europe, and data-center and telecom investment in Southeast Asia. 1.6 Industry Value Chain Upstream materials include high-purity silicon tetrachloride, germanium tetrachloride, fluorine- and phosphorus-containing dopants, oxygen, chlorine, silica tubes, core rods, and overclad tubes, together with deposition, consolidation, elongation, sleeving, and inspection equipment. Midstream production includes vapor deposition, core and cladding doping, soot-body consolidation, vitrification, elongation, sleeving, collapse, geometric inspection, refractive-index-profile measurement, and defect screening. Corning's published OVD process describes deposition of ultra-pure vapor materials to form a soot preform, followed by consolidation into transparent glass. Downstream processes include fiber drawing, coating, coloring, and proof testing, followed by cable, patch-cord, MPO/MTP assembly, and data-center connectivity manufacturing. Key barriers include high-purity glass synthesis, complex profile design, dopant uniformity, large-preform defect control, bend-performance consistency, and drawing yield. 1.7 Policy, Barriers, Challenges, and Future Trends Investment in AI infrastructure, broadband, FTTH, and data centers supports long-term demand, but the industry remains constrained by capital intensity, energy consumption, high-purity raw-material supply, environmental requirements, yield ramp-up, and lengthy customer qualification. Defects in large preforms can be amplified during drawing and may reduce attenuation performance, bending performance, or usable fiber yield. Rapid price increases benefit vertically integrated producers but can also trigger capacity additions and inventory adjustments. As supply expands, standard products may face pricing pressure, while high-performance A2 preforms, large-diameter products, reduced-coating-diameter compatibility, and data-center-qualified products are expected to maintain higher value. Future development will focus on larger preforms, faster deposition and drawing, lower attenuation, tighter macrobending consistency, and lower energy consumption per unit. Demand for 200 μm and smaller coating diameters, high-fiber-count microcables, and preconnectorized systems will require closer co-design across preform, fiber, cable, and connectivity products. 1.8 Conclusion The G.657.A2 optical fiber preform market is entering a structurally driven growth phase, powered by the convergence of AI data-center expansion, dense optical interconnection, and the replacement of conventional single-mode fiber with bend-insensitive alternatives. G.657.A2 has moved from a telecom-access specialty product to a foundational material for next-generation data-center and high-density network architectures. As demand accelerates, the competitive advantage will shift decisively toward vertically integrated suppliers with proprietary deposition technology, high-purity material control, large-preform manufacturing capability, and established qualification channels into data-center and telecom customers. The ability to scale high-performance preform capacity while maintaining consistency, yield, and cost discipline will define market leadership in the years ahead.
