Mining stainless steel tube armored optical cable (GTXTS3Y) is a seamless tube formed by putting 250μm colored optical fiber into loose-tube stainless steel tube, longitudinally welding the steel tube strip after molding, and filling special fiber paste in the middle, which can protect the optical fiber well, and at the same time, it is reinforced by twisted steel wire rope, which has the characteristics of high tensile strength, high compressive strength and high wear resistance. The outer sheath is sheathed by extrusion process, which has strong impact damage resistance. It can resist all kinds of harsh conditions, can be used in the fields of communication, temperature measurement, distributed optical fiber sensing and so on under outdoor special environmental conditions, and is especially suitable for areas where the mine roof is broken, frequently transported or easily damaged by external forces.
