HI 780 HI 780C Specialty Fiber Product Information Sheet - 1

Page 1 Corning® HI 780 & HI 780C Specialty Optical Fibers High Index / Bend Insensitive Manufactured with Corning’s patented Outside Vapor Deposition (OVD) process, Corning® HI 780 Specialty Fiber offers world-class durability and reliability. When used as component pigtails, this fiber allows for efficient fiber coupling within photonic products. It also offers reduced bend attenuation due to its high core index of refraction. Corning® HI 780 Specialty Fiber is capable of operating with short wavelength laser and LED sources. Corning now offers a re-engineered version, HI 780C, which delivers non-adiabatic taper loss during component manufacturing. HI 780C is a coupler-optimized design that allows for steeper tapers and shorter couplers with lower losses. Applications: „h Low loss fused fiber couplers „h Component fiber for couplers, and other DWDM components „h Short wavelength laser and LED sources „h Sensors and gyroscopes Features: „h Outstanding consistency and uniformity using Corning’s patented Outside Vapor Deposition (OVD) process „h Dual acrylate coating system provides excellent protection from microbend-induced attenuation and superior mechanical robustness „h Excellent geometry control „h High core index of refraction „h Efficient coupling „h High numerical aperture M0100006 Issued: March 2010 Supersedes: January 2008 For low loss fused couplers, high performance components and small footprint assemblies
