Characteristics of single-mode 4-core optical cable Controlling the excess length of the optical fiber ensures 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 oil The paste provides critical protection for the optical fiber. The specially designed tight cable structure effectively prevents the casing from retracting. It has good pressure resistance and flexibility. Double-sided chrome-plated plastic 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.
