Global G.652D Optical Fiber Preform Market Strategic Research Report

Scope of the Report

The global G.652D Optical Fiber Preform market size is predicted to grow from US$ 2,502 million in 2025 to US$ 3,707 million in 2032; it is expected to grow at a CAGR of 5.8% from 2026 to 2032.

G.652D optical fiber preforms are high-purity quartz glass substrates used to manufacture single-mode optical fibers that comply with the ITU-T G.652.D standard; they serve as a core intermediate material in the fiber production process. Through a fiber-drawing process, these preforms are converted into G.652D single-mode fibers, which are primarily utilized in optical communication sectors such as long-distance communication, data transmission, 5G networks, data center interconnects, and metropolitan area networks. In 2025, the global sales volume of G.652D optical fiber preforms reached 93,000 tons, with a production capacity of approximately 130,000 tons, an average selling price of $27.5 per kilogram, and an average gross profit margin of 25%–35%.

G.652D optical fiber preforms primarily consist of a high-purity silicon dioxide (SiO₂) glass core and cladding structure, fabricated using processes such as Chemical Vapor Deposition (CVD), Modified Chemical Vapor Deposition (MCVD), Outside Vapor Deposition (OVD), and Vapor Axial Deposition (VAD). Key technical requirements include low fiber attenuation, low dispersion, high mechanical strength, and long-term transmission stability, ensuring the resulting G.652D fibers meet the demands of high-speed communication at the 1310 nm and 1550 nm wavelengths.

The development of manufacturing technology for G.652D optical fiber preforms focuses primarily on enhancing optical performance, reducing manufacturing costs, and improving production efficiency. Current mainstream processes include Modified Chemical Vapor Deposition (MCVD), Outside Vapor Deposition (OVD), Vapor Axial Deposition (VAD), and Plasma Chemical Vapor Deposition (PCVD). Leading manufacturers typically achieve lower-loss and more consistent fiber products by optimizing deposition efficiency, controlling doping concentrations, and increasing preform dimensions. Driven by the growth of high-speed communications and data center applications, preform technology is evolving toward lower loss, larger sizes, and higher efficiency; simultaneously, some companies are expanding into new product categories—such as G.654 ultra-low-loss fibers and G.657 bend-insensitive fibers—to meet the demands of ultra-high-speed transmission and specialized applications.

Global digitalization efforts are driving sustained investment in optical communication networks across various countries, with 5G deployment, gigabit broadband, data centers, and AI infrastructure serving as key policy-driven catalysts for the rising demand for optical fiber. China continues to advance strategies such as "Digital China" and the "East Data, West Computing" project, accelerating the construction of data centers, computing power networks, and communication infrastructure to support the domestic optical fiber preform industry. Meanwhile, Europe and the United States are expanding optical fiber network coverage through broadband infrastructure investment initiatives. Furthermore, the recent surge in AI data center construction has significantly boosted the demand for high-speed optical interconnects; tight fiber supplies in certain regions have prompted major manufacturers to accelerate capacity expansion and supply chain development. Given the lengthy construction cycles for optical fiber preform production lines and the time required to bring new capacity online, the industry's short-term supply-demand balance remains constrained by the pace of capacity expansion.
