Central loose tube light armored fiber optical cable(GYXTW)

Product Description

The structure of GYXTW cable is 250µm optical fiber ribbon is inserted into a loose tube of high modulus material. The loose tube is filled with gel filling compound. The loose tube is covered by a PSP longitudinal. Water-blocking material is added between the metallic strength member and loose tube to ensure the compactness of optical cable and longitudinal water seepage of optical cable.Two parallel steel wires are placed on both sides,and then the cable is completed with PE outer sheath.

 

 

Product Characteristics

• Material of loose tube has good mechanical properties and temperature characteristics

• Material of loose tube has good hydrolysis resistance and high strength

• The tube is filled with special filler to provide critical protection for the fiber

• Good lateral pressure resistance and softness

• Double chrome plating plastic-coated steel tape (PSP) improves the moisture resistance of optical cables

• The two parallel steel wires provides enough tensile strength

• Small diameter, light weight, easy for laying
