Corning SMF-28 Optical Fiber is a single-mode fiber engineered for telecommunications, CATV, and enterprise network applications. Supplied on a 15,000 meter (15 km) spool, this fiber delivers high-speed data transfer over medium distances with low polarization mode dispersion and minimal attenuation. Manufactured using Corning’s OVD process, it ensures consistent geometrical properties and exceptional strength while maintaining ITU-T G.652.D compliance and backward compatibility with legacy G.652 infrastructure.
