The exterior of the cablecore is coated with a polyethylene inside liner, the polyethylene inside liner is sequentially coated with an outer shielding layer, a silica gel fireproof layer, a mica tape layer, a high-flame-retardance halogen-free low-smoke flame-retardant sheath layer and a water-blocking layer, and the gaps between the polyethylene inside liner and the cable wire cores, the gap between the polyethylene inside liner and the optical cable wire core, and the gaps between the polyethylene inside liner and the filling ropes are filled with insulation foaming layers. According to the flame-retardant opticalfiber composite cable, the advantages of all materials are fully utilized, so that the overall oil resistance, acid resistance and anticorrosion properties of the cable are good, the cost is saved, the compressive property and the tensile property of the cable are further improved, the overall flexible property of the cable is good, and the service life of the cable is greatly prolonged.
