Armored outdoor GYTS Steel polyethylene clung sheath with steel wires in side

The cable fiber count is normally 4-12 core, 4 or 6 fibers per loose tube,total 5 tube units surrounding 1 FRP  in the middle of the cable,some times when the tube unit less than 5pcs,will correspondingly use  some Fillers to instead of shortage tube units to keep the stability of the cable structure.Scattered in the tube units are several water-blocking yarns to prevent water moisture, a layer of corrugated steel tape wrapped outside of tube units  to prevent rat damage, water moisture resistance and also ,together with two parallel steel  wire function as tensile strength meber reinforcing the cable tension strength,the utmost PE outer sheath integrates all above to be a compact optical fiber cable
