The product characteristics of gyty optical cable control the excess length of the optical fiber to ensure the mechanical properties and temperature characteristics of the optical cable. The loose tube material itself has good hydrolysis resistance and high strength, and the tube is filled with special grease to protect the optical fiber. Provides critical protection. The specially designed compact optical cable structure effectively prevents the casing from retracting. Good pressure resistance and flexibility. Double-sided chrome-plated plastic-coated steel strip (PSP) improves the moisture resistance of the optical cable. Two parallel steel wires Ensure the tensile strength of the optical cable. The polyethylene (PE) sheath has good anti-ultraviolet radiation performance, is small in diameter, light in weight, and easy to lay.
