The Corning SMF-28 is a single-mode optical fiber designed for high-performance data transmission across metro networks, campus backbones, and broadband distribution systems. This 20 km spool delivers ITU-T G.652 compliant performance with precise core and cladding geometry that minimizes splice loss and maintains signal integrity. The fiber operates at standard telecommunications wavelengths of 1310 nm and 1550 nm, making it compatible with industry-standard optical networking equipment and fusion splicing systems.
