The Corning SMF-28e is a single-mode optical fiber delivered on a 30 km spool, engineered for long-haul and access network deployments. Operating across 1260 nm to 1625 nm, it delivers low attenuation and controlled dispersion characteristics with enhanced macrobend resistance. The fiber meets ITU-T G.652.D, IEC 60793-2-50 Type B1.3, TIA/EIA 492-CAAB, Telcordia GR-20-CORE, and ISO 11801 OS2 standards, ensuring full backward compatibility with installed legacy networks.
