GYFXY fiber cable is self-supported outdoor cable designed for aerial network construction and underground cable ducting. The structure of GYFXY cable is covering singlemode or multimode fibers into HDPE sheath, there are full of compound gel inside cable against water. Loose tube and water-proof gel make sure fiber’s tight and water-resistance performance. There are 2 parallel steel wires at PE sheath as strengthen member to guarantee cable’s tensile and pulling strength. The special tight structure can prevent loose tube retracting. Accurate fiber excess length makes sure cable’s good mechanical performance. Loose tube equips good water-proof performance and high strength with special compound gel, all these provide key protect to inside fibers.
