Description
In OMC’s 2-12F Double Sheath Unitube Armored Cable (GJFXTKV53) Glass Yarn PE cable, 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 Double sheath PE materials jacket to guarantee the compactness and longitudinal water-blocking performance.
