GYHTY Loose Tube Laye Staranded Non-Metallic Strength Member GYHTY optical fiber cable
The structure of GYHTY optical fiber cable 250µm fiber is positioned in a loose tube made of high modulus material,
and the loose tube is filled with waterproof compound. The center of the cable core is a metallic Fiber Reinforced
Plastic (FRP)，for some cores fiber cable, a layer of polyethylene (PE) needs to be extruded outside the metallic central
strength member. The tubes (and filling rope) is stranded around the central reinforcing core to form a compact and
circular cable core. After the cable core is filled with the filling compound to protect it from water ingress, it is covered
with thin PE(polyethylene) inner sheath. Then a layer of aramid yarn is applied as additional strength member and the
cable is completed with a polyethylene(PE) outer sheath.
Loose Tube Optical Cable Features
① Excellent mechanical property and temperature performance.
② Aramid yarn strength member ensure good performance of tensile strength.
③ Good crush resistance and flexibility.
④ Loose tube material has good hydrolysis resistance and higher intensity.
⑤ Single FRP as the central strength member to withstand axial loads.
⑥ PE sheath protects cable from ultraviolet radiation.
⑦ Fully cable core filled.
