Abstract : Demands for composite cables containing optical fibers and multi pairs have been increasing for an economical and a systematical point of view. In reply to such demands, we have developed and manufactured a composite submarine cable containing 8 GI type fibers and 50 pairs of 0.9 mm copper conductors. This paper describes the construction of the composite cable and the loss characteristics of the optical fibers against various mechanical forces due to the armouring process and the installation and also describes the evaluation of the life time of the optical fibers determined by various tensions and remained stress in fibers. We confirm the reliability of the newly developed composite submarine cable for an actual use. (Author)
