Shanghai Gengyun Industrial Co., Ltd
The structure of GYFXY unitube non-metal loose tube fiber cable is to insert 250 µm optical fiber into a loose tube made of high modulus material, and fill the loose tube with waterproof compound. Loose tube with added water blocking material to ensure longitudinal water blocking of the optical cable. Two parallel FRP reinforcement pieces are placed on both sides and extruded into a polyethylene sheath to form the cable.
Standard
YD/T 769;
Feature
1.Unitube loose tube fiber cable has excellent mechanical properties and temperature characteristics;
2.The loose tube material itself has good hydrolysis resistance and high strength;
3.The tube is filled with special ointment to provide critical protection for the optical fiber;
4.Two parallel FRP ensure the tensile strength of the optical cable;
5.PE sheath has excellent resistance to ultraviolet radiation;
6.Small diameter, lightweight, and easy to lay;
7. Non-metallic fiber cable has long delivery length;
