Uni-Tube GYXTW Single Mode 4 Cores Fiber Optic Cable
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.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
