SMF-28® Ultra single-mode optical fibers combine industry-leading attenuation, macrobend performance that exceeds ITU-T G.657.A1, and favored 9.2 µm mode field diameter. These fibers are designed for carrier (access, mobile, FTTH) and data center (indoors, DCI) applications and are fully backward compatible with the installed base of legacy single-mode fibers. With SMF-28 Ultra fibers, network operators have the freedom to deploy fiber-rich cables to address capacity and congestion.
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.
