Stainless steel tube armored patch cord optic cable (GTXJGH) is a seamless steel tube formed by putting 0.6mm or 0.9mm optical fiber into loose tube stainless steel tube, and the steel tube strip is formed by laser longitudinal welding. The optical fiber tightly sheathed in the middle is coated with a special material buffer layer, which forms a good protection for the optical fiber. The optical cable has excellent mechanical properties and is easy to be processed later. It is an excellent transmission medium in the communication field. Products are widely used in 5G communication, radio and television systems, intelligent building control, power control systems, transportation communication systems, metropolitan area networks and local area networks.
