SKU: SMF
Corning high-purity silica single-mode fibers are manufactured to stringent industry standards using advanced chemical vapor deposition technology. Featuring germanium-doped silica cores and engineered silica claddings, these fibers offer excellent geometrical precision, optical performance, environmental stability, and mechanical reliability. Their low optical attenuation and high material purity make them particularly suitable for high-power optical transmission and precision fiber-optic applications. We offer a comprehensive selection of Corning single-mode fiber families for operation across the O-, C-, and L-bands, including standard SMF-28 for cost-effective applications, SMF-28 Ultra for reduced attenuation and improved bending performance, SMF-28e and ClearCurve XB for enhanced transmission and bend resistance, and LEAF fiber for applications requiring nonzero dispersion characteristics and chromatic dispersion management.
