Corning 048KU4-T4730D20 – 48-F OM1 62.5 µm LT Duct/Aerial Outdoor, Gel-Free, 3.4/1.0 dB/km, Altos Fast Access

Corning 048KU4-T4730D20 – 48-F OM1 62.5 µm LT Duct/Aerial Outdoor, Gel-Free, 3.4/1.0 dB/km, Altos Fast Access

This 48-fiber OM1 loose tube cable is designed for outdoor duct and aerial installations, featuring a gel-free construction for simplified handling and rapid deployment. The cable has a dielectric central element and a robust black polyethylene jacket for environmental protection while maintaining optical performance. Water-swellable tape offers moisture resistance, and the fibers are color-coded according to Telcordia standards for easy identification. Supporting 62.5 µm multimode OM1 performance, it delivers low attenuation at 850/1300 nm and sufficient bandwidth for 1 Gigabit Ethernet over 300–550 meters. With high tensile strength and ANSI/ICEA S-87-640 compliance, this cable is ideal for reliable, long-term outdoor network infrastructure.
