The invention belongs to the technical field of optical cables, and relates to a high-flame-retardant optical cable for subway tunnels. The high-flame-retardant optical cable for the subway tunnels includes a cable core, and an inner flame-retardant layer, a composite steel wire armor layer and a composite flame-retardant sheath layer which cover the cable core from the inside to the outside. Theoptical fiber, the flame-retardant water-blocking fiber paste, a flame-retardant loose tube, a central reinforcing member and the flame-retardant water-blocking cable paste form the cable core havingflame-retardant and water-blocking properties. In the invention, the multi-layer flame-retardant structure design of the cable core, the inner flame-retardant layer and the composite flame-retardant sheath layer makes the cable burn in the fire without generating toxic gases and smoke, normal communication transmission can be ensured in the event of fire, real-time monitoring of temperature is realized, fire hazards are reduced, and life and property and safety can be ensured; and the combination of the composite steel wire armor layer and the composite flame-retardant sheath layer forms a multi-channel defense against rat and ant bites, enhances the shielding performance and the tensile performance of the optical cable, and prevents the armor layer from " lantern " during the armoring process. The invention is suitable for data transmission in the fields of modern rail transit and the like.
