Description
In OMC’s 2-24F Unitube Armored Cable (GYXTS) With Aramid Yarn, single-mode/multimode fibers are positioned in the loose tube, which is made of PBT materials and filled with filling compound. The loose tube is covered with Aramid Yarn, Steel armored tape and PE materials to guarantee the compactness and longitudinal water-blocking performance.
