GYDXTW Central Tube Type Lightweight Armored Fiber Ribbon Optical Cable

Product Description:

A 12-core fiber ribbon is placed into a loose tube made of  high-modulus, hydrolysis-resistant material, which is  filled with thixotropic water-blocking gel. A layer of  double-sided coated steel tape is longitudinally wrapped  around the loose tube, and water-blocking gel is filled  between the steel tape and the loose tube to ensure the  compactness and longitudinal water blocking of the  optical cable. Two parallel steel wires are placed on both  sides, and then the cable is extruded with a flame  retardant sheath.


Product Feature:

◆ Exhibits good mechanical performance and  temperature characteristics. 

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

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

◆ Precise control of excess length of optical fibers inside  the loose tube and excess length of cable core structure  ensures that the cable meets the tensile performance  and temperature characteristics required by product  standards. 

◆ 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
