The invention relates to a high-count heavily-armored optical cable comprising fibers, fiber straps, fiber paste, a restraining tube, a water-stop member, an inner protective layer, thin round steel wires and an outer protective layer. The outer protective layer, the inner protective layer and the restraining tube are arranged in order from outside to inside. The fibers wrapped with the fiber straps are arranged within the restraining tube. The water-stop member and a reinforcing member are evenly applied to the outside of the restraining tube, thereby forming a core; the thin round steel wires and the water-stop member are evenly applied to the periphery of the outer protective layer and the inner protective layer. The high-count heavily-armored optical cable has the advantages that the outer diameter is low, the core count is high, the structure is complete, mechanical properties are good, the internal structure can be effectively protected in severe environments, and compared to the like products, the high-count heavily-armored optical cable has weight greatly reduced and is easier to lay and maintain later.
