Corning 012TUL-T4680D2N — Indoor/Outdoor Fiber Cable, OM3, Loose Tube, Black, Armored

The Indoor/Outdoor Fiber Cable, OM3, Loose Tube, Black, Armored is a high-performance, dielectric, loose tube fiber optic cable designed for aerial, duct, and tray-rated applications. With a 12-fiber OM3 multimode configuration, it supports high-speed data transmission with minimum effective modal bandwidth (EMB) of 950 MHz·km and OFL bandwidth of 1500 MHz·km at 850 nm. This LSZH (Low Smoke Zero Halogen) flame-rated cable is sunlight resistant, suitable for direct burial, and engineered to withstand harsh installation environments with a temperature range from -40 °C to 70 °C. Its rugged construction features multiple water-swellable tapes, FRNC/LSZH inner and outer jackets, and dielectric strength members for exceptional tensile strength (up to 4500 N short-term). Ideal for industrial and telecom networks, it combines durability, safety, and optical performance in one robust solution.
