Optical cables are divided into metal and non-metallic models, which can be made of a single steel wire or a steel wire rope composed of high-strength steel wires. Non-metal optical cables generally use FRP. The use of optical cable strengths is determined according to the type of optical cable and use requirements. , and determine the specifications of the reinforcement according to the requirements of the tensile strength of the optical cable. According to the industry standard, the Young's modulus of the steel wire should not be lower than 190GPa, the Young's modulus of the steel wire rope should not be lower than 170GPa, and the non-metal reinforcement should not be lower than 50GPa. . And the optical cable with complex structure and large number of cores has higher requirements. It needs to meet the short-term and long-term pulling requirements of a certain type of optical cable!
