The Japan Marine Science and Technology Center (JAMSTEC) has been developing many kinds of seabed survey systems. The Dolphin 3 K system, a new unmanned deep submergence vehicle capable of diving to a depth of 3300 m was developed to survey the seabed where it is too dangerous for manned deep submergence vehicles to approach, and where the depth exceeds 2000 m. A 5000 m long optical fiber/power composite tether cable is used for electric power and signal transmission to control the vehicle. It comprises a compact, optical fiber/power composite, underwater connector and a compact mechanical cable termination for the Dolphin 3 K system. This tether cable system is required to be highly reliable under a water pressure of up to 376 kg/cm2, side-wall pressure of 20 ton/m, high tensile strength of 1.6.5 tons, and have high bending endurance properties. The Dolphin 3 K system was equipped on a supporting mother ship, and sea trials to a depth of 3400 m have been satisfactorily conducted.
