The Corning SMF-28e is a single-mode optical fiber supplied on a 15 km spool, engineered for enterprise networks, 5G backhaul, and cloud infrastructure. This fiber delivers low attenuation across C-band and L-band wavelengths while maintaining exceptional macrobend performance. It meets ITU-T G.652.D and G.657.A1 standards, ensuring compatibility with existing deployments and support for 10G/40G/100G+ systems.
