non-corrosive stainless steel tube armored optical cable (GTXTGSG) is a seamless steel tube made by putting 250μm colored optical fiber into a loose-tube stainless steel tube, longitudinally welding the steel tube strip by laser, filling a special fiber paste buffer layer in the middle, thus forming good protection for the optical fiber, and at the same time being able to longitudinally block water. The steel wire between the inner steel tube and the outer steel tube is twisted. The seamless steel tube is used to wrap the high-temperature resistant optical fiber, and the steel wire armor is combined with the seamless steel tube sheath, which has excellent compression resistance, tensile resistance and gas shielding performance, and is suitable for being buried in corrosive environment for a long time.non-corrosive
