PRODUCT OVERVIEW

GYTA fiber cable is self-supported outdoor cable designed for aerial network construction and underground cable ducting. The structure of GYTA cable is to put singlemode or multimode fiber counts into polyester loose tube which are full of compound gel against water. There is steel wire in the middle of cable as strengthen member. For some certain counts GYTA cable, steel wire needs to cover PE to increase tensile. Loose tubes embrace central strengthen core to form tight round cable, gaps within cable will be filled with compound water-proof gel.

Shortly, GYTA 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
