Composite optical cable

The invention discloses a composite optical cable which comprises a skeleton groove member, a plurality of grooves are uniformly distributed in the periphery of the skeleton groove member in the circumferential direction, and an optical fiber is placed in each groove; the central optical fiber unit is positioned at the central hole of the skeleton groove piece; the reinforcing piece layer comprises a plurality of reinforcing pieces which are annularly arranged and sequentially attached to one another, and the reinforcing pieces are embedded into the inner side part of the framework groove piece and/or embedded into the sheath layer of the central optical fiber unit; and the outer sheath wraps the outer side of the skeleton groove piece. The reinforcing piece layer is arranged in a pipe shape, so that the central cavity can accommodate the optical fiber part of the central optical fiber unit, the whole composite optical cable can increase the number of optical fibers, the utilization rate of the optical fibers
