Description
In OMC’s 12-288F Stranded Loose Tube No-Armored outdoor cable-GCYTY, A FRP wire, sometimes sheathed with polyethylene (PE) is located in the center of core as a No-metallic strength member. single-mode/multimode Fiber are positioned in the loose tube, which is made of PBT materials and filled with filling compound. The loose tube is covered with PE materials to guarantee the compactness and longitudinal water-blocking performance.
