FTTH Outdoor Fig 8 Cable GYXTC8Y

Short Description:

The mental strength member is made up of stranded steel wires as the supporting part are completed with a polyethylene(PE) sheath to be figure 8 structure. Corrugated steel tape armored and PE outer sheath providing crush resistance and gun shot resistance features. The steel-wire strength member as the central strength improves the tensile strength and it is surrounded by the loose tube and water blocking system. The impact structure ensures excellent mechanical and environmental performance.
