GYXTZW Central Tube Type Flame-retardant 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.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 resistanceand excellent pressure resistance. 

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

◆ Special sheath material has excellent flame retardant  properties. 

◆ 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
