Loose tube is made of colored optical fiber without filling waterproof compound. Loose tubes are stranded around the strength member which are in the central of cable into cable core, a layer of water-blocking tap is longitudinal wrapped around the cable core, after corrugated steel is longitudinal wrapped, an outer jacket is extruded.
