Based on a theoretical study of hydrofluoric-acid etching, a maximum strain of 3.3-percent elongation was achieved at the spliced point of the fiber. A new reinforcement method has also been developed which provides a long-length fiber for cabling. An optical fiber containing these splices was cabled without degradation in optical transmission loss. Furthermore, proof testing for the spliced portions of submarine optical-fiber cable is taken into account in order to assure mechanical reliability in the manufacturing, laying, recovery, and repair of the cable.
