LOOSE TUBE LAYER STRANDED NON-METALLIC REINFORCED CORE FIBER OPTIC CABLE GYHTY
The structure of GYHTY fiber optic 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 ofthe cable coreis a glass fiber Reinforced Plastic (FRP), for some cores fiber cable, a layer of polyethylene (PE needs to be extruded outside the non-metalic central strength member.The tubes (and fling rope) is stranded around the central reinforcing core to form a compact and circular cable core After the cable core is filed with the filing 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.

Description
The structure of GYHTY fiber optic 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 ofthe cable coreis a glass fiber Reinforced Plastic (FRP), for some cores fiber cable, a layer of polyethylene (PE needs to be extruded outside the non-metalic central strength member.The tubes (and fling rope) is stranded around the central reinforcing core to form a compact and circular cable core After the cable core is filed with the filing 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.
Features
① Excellent mechanical property and temperature performance.
② Aramid yarn strength member ensure good performance oftensile 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.
