Corning 012TU4-T4731D20 – 12-F OM2 50/125 LT Duct/Aerial Outdoor, Gel-Free, 3.0/1.0 dB/km, Altos Fast Access

Corning 012TU4-T4731D20 – 12-F OM2 50/125 LT Duct/Aerial Outdoor, Gel-Free, 3.0/1.0 dB/km, Altos Fast Access

This 12-fiber OM2 loose tube cable is designed for reliable outdoor duct and aerial installations, offering gel-free construction for simplified handling and fast access. It features a dielectric central element and a durable black polyethylene jacket, providing excellent mechanical and environmental protection. Water-swellable tape ensures moisture resistance, while fibers are color-coded per Telcordia standards for easy identification. Supporting 50 µm multimode OM2 fibers, the cable provides low attenuation at 850/1300 nm and high bandwidth for 1G and 10G Ethernet applications. Engineered to ANSI/ICEA S-87-640 standards, this cable delivers strong performance, durability, and efficient deployment for outdoor network infrastructure.
