Description
In OMC’s 12F Stranded Loose Tube Armored Cable GYFHTS cable, A FRP is located in the center of core as a 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 Water Blocking Tape+ Corrugated Steel tape. A PE materials cable Jacket guarantee the compactness and longitudinal water-blocking performance.
