Industry-leading attenuation with ITU-T G.657.A1 bend and 9.2 µm mode field diameter in traditional and reduced diameters

Corning® SMF-28® Ultra Optical Fibers

Corning® SMF-28® Ultra Optical Fibers

SMF-28® Ultra single-mode optical fibers combine industry-leading attenuation, improved macrobend performance, and standard 9.2 µm mode field diameter. These full-spectrum fibers are designed for carrier and data center applications and are backward compatible with the installed based of legacy single-mode fibers. They have bend performance that exceeds Recommendation ITU-T G.657.A1 and are fully compliant with ITU-T G.652.D.

SMF-28 Ultra fiber is available in a traditional 242 µm diameter as well as a reduced 200 µm diameter option for smaller, lighter, high-fiber-count cables.
