GYXTW Single Mode Outdoor Duct Aerial Application Light Armored Cable
GYXTW Single Mode Outdoor Duct Aerial Application Light-Armored Cable
Description
GYXTW fiber optic cable is made of 250μm optical fiber in a high-modulus material pine sleeve filled with waterproof compound. The loose tubing is wrapped longitudinally with a double-sided plastic coated steel tape (PSP). The water barrier material is added between the steel tape and the loose tubing to ensure compactness and longitudinal water resistance of the fiber optic cable. Two parallel steel wires are placed on both sides and then extruded into a polyethylene sheath to form the cable.
Armored Uni-Tube Single Jacket/Single Armor fiber optic cable with fibers placed in loose buffer tube. The cable core is protected with a corrugated steel tape armor and cover with a black polyethylene outjacket. Two embedded steel wire provide desire tension.
