The invention discloses a nonmetal armored optical cable. The nonmetal armored optical cable comprises an outer sheath layer, a cable core and an armor layer internally filled with a water-blocking factice, the outer sheath layer, the armor layer and the cable core are arranged in sequence from outside to inside, nonmetal reinforcers are arranged between the outer sheath layer and the armor layer and between the armor layer and the cable core, the armor layer is a spring-shaped engineering plastic pipe, and the cable core is a tight tube optical fiber. The nonmetal armored optical cable has a simple structure, a reasonable design and a good using effect, can effectively increase flexibility and a compression resistance capability, and a rodent-attack-resistant capability of the optical cable, is low in cost and light in weight, and is easy to popularize and use.
