Description
In OMC’s 1F 5.0mm Central Loose Tube indoor&Outdoor cable without Jelly High Tensile, single-mode/multimode fibers are positioned in the loose tube, which is made of PBT materials and filled with water Blocking Yarn. The loose tube is covered with Aramid Yarn and LSZH materials jacket to guarantee the compactness and longitudinal water-blocking performance.
