A layer-twisting ADSS optical cable relates to an optical cable for power communication. The optical cable comprises a cable core and a sheath, wherein the sheath wraps up the cable core, the cable core comprises a reinforcing core and a fiber unit, the reinforcing core is positioned in the central section of the cable core, and the fiber unit is arranged in a loose sleeve which is vertically twisted outside the reinforcing core. The optical cable is characterized in that the sheath comprises a reinforcing layer and an outer protection layer, wherein the outer protection layer wraps up the reinforcing layer, the reinforcing layer wraps up the cable core, a water resisting band is laid between the cable core and the reinforcing layer, and a bird damage-preventing protective layer is arranged outside the outer protection layer. The bird damage-preventing protective layer is formed by longitudinal wrapping or winding of reinforced fiber bands. A polyethylene external sheath is laid outside the bird damage-preventing protective layer, protrusions are arranged on the outer wall of the reinforcing layer, and position clip structures matching with the protrusions are arranged on the inner wall of the outer protection layer. Slipping between layers of the sheath can be prevented, and bird damage can be prevented. The layer-twisting ADSS optical cable is light and has high practical and promotion value.
