Abstract
The present invention relates to a submarine optical fiber cable which is comprised of a plurality of relatively large diameter tension wires wound around an optical fiber unit in a close fitting manner so as to form a single layer which acts as a tension body, and root portions between the first tension wires caused by winding the first tension wires which covered by relatively small diameter second tension wires. Due to the second tension wires, deformation of the tension body of the stranded wires can be prevented and the pressure resistance and the tensile strength can be improved.
