The CORNING SMF-28e+ is a single-mode optical fiber engineered for high-performance telecommunications and data transmission across metropolitan, access, and long-haul networks. This ITU-T G.652.D compliant fiber delivers reduced attenuation in the water-peak region (1360 nm – 1460 nm), enabling full-spectrum operation from 1260 nm to 1625 nm with minimal signal loss. The 15 km spool provides a ready-to-deploy solution for carriers and enterprises requiring reliable, standards-based connectivity.
