PRODUCT DETAILS

Steel Tape Layer Loose Tube Outdoor Cable GYTA

The fibers, single mode or muti mode , are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Aluminum tape, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The Aluminum tape is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.
