Structure Design
Description
GYXTW cable, single-mode/multi-mode fibers are positioned in the loose tube, which is made of high modulus plastic materials and filled with filling compound. PSP is longitudinally applied around the loose tube, and water-blocking materials are distributed into interstices between them to guarantee the compactness and longitudinal water-blocking performance. Two parallel steel wires are placed at both sides of the cable core while PE sheath is extruded over it.
Application
Aerial/Duct/Outdoor.
Feature
1.Excellent mechanical and temperature performance guaranteed by the accurate excess fiber lent；
2.Critical protection to fibers, based on the excellent hydrolysis resistance；
3.Excellent crush resistance and flexibility；
4.PSP enhances the cable crush-resistance, impact-resistance and moisture-proof；
5.Two parallel steel wires ensure tensile strength；
6.Excellent ultraviolet prevention with PE sheath，small diameter, light weight and installation friendliness.
