Home>Products>Outdoor Optical Cables>Central Tube Type A-Sheath Rodent-Resistant Optical Cable
The GYXTA optical cable structure involves placing multiple optical fibers into a loose tube made of high-modulus polyester material, with the tube filled with waterproof compound. The loose tube is wrapped with water-blocking material to ensure longitudinal water resistance. After the cable is formed with stranded steel wire armor, a plastic-coated aluminum tape (APL) is longitudinally applied, followed by extrusion of a polyethylene outer sheath.

1. Precisely controlled fiber excess length ensures excellent mechanical and temperature performance.
2. The loose tube material itself exhibits high hydrolysis resistance and superior strength.
3. Filled with specialized thixotropic gel, providing critical protection to the fibers.
4. Good lateral crush resistance and flexibility.
5. A layer of stranded steel wire armor ensures tensile strength and provides effective rodent resistance.
6. Plastic-coated aluminum tape (APL) moisture barrier.
7. Effective water-blocking materials prevent longitudinal water seepage.
8. The polyethylene (PE) sheath offers excellent UV radiation resistance.
9. Small diameter facilitates easy installation.
