TF-1LG-036-R25N is a factory-grade indoor/outdoor multi-loose-tube fiber optic cable designed for extended distance horizontal and backbone data/telco network applications. It features 36 OM1 multimode fibers with 62.5 µm core diameter arranged in 3 active subunits of 12 fibers each, with gel-filled 2.8 mm tubes for waterblocking protection. The cable incorporates a double jacket construction using PVC material with waterblocking aramid yarn strength members, achieving a nominal outer diameter of 13.1 mm. With an operating temperature range of -40°C to +70°C and OFNR/FT4 flammability ratings, this cable offers sunlight, oil, ozone, and hydraulic fluid resistance for demanding environments. It supports 1 Gigabit Ethernet up to 550 m at 1300 nm and provides maximum tensile strength of 2670 N during installation.
