Description
In OMC’s 2–24cores Unitube Armored Cable (GYXTS) With Water-blocking Glass 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 Water-blocking Glass Yarn . Steel armored tape and HDPE materials to guarantee the compactness and longitudinal water-blocking performance.
