GYXS/GYXTW Center Tube Type Lightweight Armored Optical Cable

Product Description:

Colored optical fibers are placed into a loose tube made of  high-modulus, hydrolysis-resistant material, which is filled with  thixotropic water-blocking gel. The loose tube is longitudinally  wrapped with a layer of double-sided coated steel tape, and  water-blocking gel is filled between the steel tape and the loose tube  to ensure the cable's compactness and longitudinal water-blocking.  Two parallel steel wires are placed on both sides and then extruded  with a polyethylene sheath to form the cable.


Product Feature:

◆ Exhibits good mechanical performance and temperature  characteristics. 

◆ The material of the loose tube has good hydrolysis resistanceand  excellent pressure resistance. 

◆ Filled with special grease inside the tube, providing crucial  protection for the optical fibers. 

◆ Double-sided coated steel tape enhances the cable's resistance to  moisture penetration. 

◆ Two parallel steel wires ensure the stability and tensile  performance of the cable. 

◆ Small diameter, lightweight, and easy to install.


Application: Ducts, Aerial
