1310, 1550 nm; Core Dia. 8.2 µm (Nominal); Cladding Dia. 125 µm; Dual Acrylate Coating; Hermetic Layer; -60 to +85 °C Corning’s SMFHA hermetic single mode (SM) optical fibers are designed for applications requiring improved fatigue resistance, high useable strength and excellent resistance to hydrogen permeation into optical fibers. For hermetic multi mode fibers please refer to Corning’s MMFHA fibers. Corning’s specialty designed hermetic layer provides a protective barrier to help shield the glass from exposure to hydrogen, water and corrosive chemicals while maintaining optical qualities comparable to standard fibers. The properties of the hermetic layer increase the fatigue performance of the fiber five times compared with non-hermetic fibers. Corning’s hermetic layer is a thin layer of amorphous carbon that is bonded to the glass surface of the optical fiber. The fiber is manufactured with Corning’s patented Outside Vapor Deposition (OVD) process. The SMFHA hermetic single mode specialty fibers offer high reliability and consistent performance for a variety of applications. Key Features: No Hydrogen Aging at Room Temperature to +85 °C Low Attenuation Outstanding Consistency and Uniformity Using Patented Outside Vapor Deposition (OVD) Process Efficient Coupling Dual Acrylate Coating System Provides Excellent Protection and Superior Mechanical Robustness Single Mode (SM) Fibers Optimized for 1310 nm and 1550 nm Wavelengths Inquire for Other Glasses Applications: Hydrogen-rich Environments; Long-distance Undersea Links; Sensors; Increased Fatigue Resistance for Tight Bend Applications
