Corning 012TU4-T4790D20 – Gel-Free Cable, OM4, Loose Tube, Black, 50µm Dia, 12 Fiber

Corning 012TU4-T4790D20 – Gel-Free Cable, OM4, Loose Tube, Black, 50µm Dia, 12 Fiber

This 12-fiber OM4 loose tube cable is optimized for outdoor aerial and duct installations, providing high-speed, gel-free performance for quick and efficient deployment. Constructed with a dielectric central element and a durable black polyethylene jacket, it is designed for long-term reliability in harsh environments. Water-swellable tape and Telcordia color-coded fibers ensure moisture resistance and easy fiber identification. OM4 50 µm multimode fibers deliver low attenuation at 850/1300 nm, supporting high-speed 1G and 10G Ethernet networks with exceptional modal bandwidth. Built to ANSI/ICEA S-87-640 standards, this cable guarantees mechanical strength, easy handling, and superior optical performance for fast access applications.
