The Corning SMF-28 single-mode fiber ships as a dual-spool kit—40 km + 40 km—with factory-installed connectors and test reports. Built using Outside Vapor Deposition (OVD), this fiber delivers ultra-pure material with consistent geometry, high strength, and low attenuation across telephony, cable television, submarine, and utility network deployments. The configuration includes protective packaging and is ready for immediate field installation.
