There are many single mode fiber equipped in the center of GYXTW ,it is filled with factice ,The outward of Loose-tube are wrapped with water proof tape and corrugated steel tape. The sheath’s outward adopt high-class black polyethylene and equipped two round steel wires in it ,which is parallel symmetric .The total cross section of this fiber is waterproof,compact configuration,small external diameter,light weight,excellent machine performance ,low loss ,low dispersion,be suit for overhead ,channel,and buried lay of digit or analog transportation system .
|1.Excellent mechanical and temperature performance guaranteed by the accurate excess fiber length.
|2.Critical protection to fibers, based on the excellent hydrolysis resistance and strength performance of tube material and special filling compound filled in the tube.
|3.Special compact structure to avoid the loose tube shrinkage.
|4.Excellent crush resistance and flexibility.
|5.PSP enhances the cable crush-resistance, impact-resistance and moisture-proof.
|6.Two parallel steel wires ensure tensile strength. Small diameter, light weight and installation friendliness with long delivery length.
|7. Excellent ultraviolet prevention with PE sheath.
