GYXTW 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.

What’s more, GYXTW cable’s accurate fiber excess length control provides good cable tensile performance. Loose tube material equips water-proof and high tensile characteristics, compound filling gel protects fibers well at loose tube. PE sheath equips good performance against ultraviolet ray. Cable adopt bellowing measures to guarantee water-proof performance: single steel wire strengthen member, special compound water-proof filling gel at loose tube, full fibers counts and ALP cover aluminum strip provides moisture-proof performance.
