Description

According to our (Global Info Research) latest study, the global G.657 Optical Fiber market size was valued at US$ 2510 million in 2025 and is forecast to a readjusted size of US$ 4735 million by 2032 with a CAGR of 9.6% during review period.
G.657 optical fiber refers to bend-insensitive single-mode fiber that complies with the International Telecommunication Union (ITU-T) G.657 standard. By optimizing the refractive index profile and core structure design, this type of fiber significantly reduces bending loss while maintaining compatibility with G.652.D single-mode fiber.
The upstream segment of the industry chain primarily includes raw materials for optical fiber preforms—such as high-purity quartz sand, silicon tetrachloride (SiCl₄), and germanium tetrachloride (GeCl₄)—as well as UV-curable coating resins, fiber coloring materials, and precision fiber-drawing equipment; notably, the manufacture of high-purity preforms and the use of trench-assisted refractive index designs are key to achieving superior bend resistance. The midstream segment involves the R&D and manufacturing of G.657 fiber; processes such as preform preparation, fiber drawing, coating and curing, and online inspection are employed to produce bend-insensitive single-mode fibers meeting ITU-T G.657.A1, A2, B2, and B3 standards, which are subsequently processed into access cables, indoor cables, and data center cables. The downstream segment sees widespread application in fields such as FTTH (Fiber to the Home), FTTB/FTTC access networks, 5G/6G communication networks, and AI data centers.
In 2025, global sales volume for G.657 fiber is projected to reach 428 million fiber-kilometers, with a production capacity of approximately 600 million fiber-kilometers; the average selling price is estimated at $5.7 per fiber-kilometer, with an average gross margin of 25%–30%.
G.657 optical fiber technology continues to evolve toward lower bending loss, enhanced compatibility, and higher cabling density. Market adoption has gradually shifted from the early G.657.A1 standard to G.657.A2, which offers superior bend resistance; the latter meets requirements for tighter bending radii and higher-density cabling while maintaining compatibility with G.652.D fiber. Looking ahead, ultra-low-loss fiber, 200 μm reduced-diameter fiber, micro-cables, and high-fiber-count cables will develop in tandem with G.657.A2, driving the evolution of access networks and data centers toward higher capacity and density.
