Description
In OMC’s 24F Stranded Loose Tube Armored (GYHTSH) LSZH cable, A steel wire &PE cushion layer(while need)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 Corrugated Steel tape, Finally The LSZH materials Jacket covered to guarantee the compactness and longitudinal water-blocking performance.
