Oil well stainless steel tube armored optical cable (GTXTGAG) is a seamless tube formed by putting 250μm colored optical fiber into loose-tube stainless steel tube, longitudinally welding the steel tube strip after forming, filling special fiber paste in the middle, forming good protection for the optical fiber, and at the same time, vertically blocking water. Three layers of metal materials are used to protect the optical fiber, so that the optical cable has relatively high-strength high-temperature and high-pressure resistance and corrosion resistance. At the same time, it also has strong mechanical properties and sealing performance, high tensile strength, high compression resistance, high wear resistance and other characteristics, and has strong impact damage resistance, which can withstand various harsh conditions, ensure transmission performance, seal design, electrochemical corrosion resistance, water resistance and oil resistance, and is suitable for oil wells and various complex and harsh natural environments.
