GYXTA33 Loose Tube Central Tube Type Single Steel Wire Armored Optical Cable

Product Description:

Colored optical fibers are placed into a loose tube made of  high-modulus and water-resistant material. The loose tube is  filled with thixotropic water-blocking gel. Around the loose tube,  there is a layer of fine circular steel wires twisted to form a  compact and round cable core. The interstices inside the cable  core are filled with water-blocking material. After longitudinal  wrapping with coated aluminum tape, it is extruded with a layer  of polyethylene inner sheath, then armored with a single fine  circular steel wire, and finally extruded with a polyethylene outer  sheath to form the cable.


Product Feature:

◆ Exhibits good mechanical performance and temperature  characteristics. 

◆ Double-layer single fine circular steel wire armor enhances the  cable's tensile strength. 

◆ 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. 

◆ Features a moisture-resistant layer of coated aluminum tape. 

◆ Small size, lightweight, and easy to install.


Application: direct burial, climbing slopes, underwater
