Abstract
The invention discloses an optical fiber cable. The optical fiber cable comprises a reinforcing core and a plurality of protection wires. The protection wires are located around the reinforcing core. A plurality of cavities are formed in the periphery of each protection wire, optical fiber bundles are arranged in the cavities respectively, and the reinforcing core and the protection wires are coated with an inner sheath and an outer sheath in sequence. The optical fiber cable is simple in structure; the optical fiber bundles are contained and protected by the protection wires and the cavities in the peripheries of the protection wires, a traditional loose tube is replaced, and the space between the optical fiber bundles in the loose tube does not need to be filled with filler, and therefore the protection technology is simplified, the cost is reduced, and the good protection effect is achieved.
