    摘要: In a submarine branching unit which comprises in a pressure-tight cylinder, a circuit board, at least one circuit unit and plural vacuum relays each having terminals and wirings, the circuit unit is mounted on one side of the circuit board; the vacuum relays are mounted on the other side of the circuit board; and insulator covers accommodate the respective vacuum relays, terminals and wirings to insulate the vacuum relays from each other. The submarine branching unit further comprises a pair of cables extending out of a cover of the pressure-tight cylinder, which cables are each spiraled and engaged with each other in an interleaved and overlapped fashion.

    摘要: An underwater cable branching apparatus has an elongate cable junction housing for positioning in line between two cables for installation underwater. The housing has through bores at each end for receiving the ends of respective first and second cables, and the cables are each terminated at a respective connector in the housing for releasably connecting the two cable ends together. Each connector is pivotally and retractably mounted in the housing by a respective pivotal linkage, such that the connectors can be separated and rotated upwardly out of the housing by an ROV for selective connection to other cables in an underwater network, to permit branching.

    摘要: The invention facilitates provision of a point-to-point cable connection between first and second points separated by an extended span of water including a first region of shallow water and a second region of relatively deep water. A plurality of ducts are provided from the first point through the first region of the extended span to an offshore termination point between the first and second points. Preferably, the ducts are buried in the seabed to prevent damage. At least one first cable is placed in one of the plurality of ducts to provide a connection between the first point and the offshore termination point. A second cable from the second point is received at the offshore termination point. The first cable is connected to the second cable at the offshore termination point to create the point-to-point cable connection. In one embodiment, the offshore termination point is located on the continental shelf near the transition to deep water. Cable can be installed between the first point and the offshore termination point with relative ease by passing the cable through an available conduit. This eliminates the need for the time consuming and expensive permitting process typically associated with near-shore cable installation.

    摘要: An underwater telecommunications system has a first underwater cable for carrying data traffic, one or more underwater repeaters, and an underwater power network for supplying power to the repeaters. By providing a separate cable for some or all of the power supply, the power route may be made shorter, thus more power can be delivered, therefore more repeaters can be used, which enables more fiber pairs to be laid, and thus the capacity to be increased.

    摘要: Submersible cables that are placed in a body of fluid such as water or other fluids such as chemicals or sewage often require a takeoff to be added to the submersible cable wherein a window is cut in the exterior insulation of the submersible cable or parent trunk exposing interior wires or fiber optical cables or tubes and the like. The device and method for this fluid stop splice for a submersible cable where the desired conductors such as wires, fibers or tubes of the takeoff are suitably spliced to the necessary or desired wires, fibers or tubes of the parent trunk cable is such that a cofferdam is placed around the spliced area of the cables, fibers or tubes and a glutinous material is pumped, poured, or injected into the cofferdam where the glutinous material cures around the splice of the cables, fibers and or tubes and further forms a fluid tight seal around the cables, fibers and tubes to further stop fluid flow into the parent truck when the primary cable and takeoff are submerged into the fluid and further prevents electrical leakage, or the distribution communication leakage of the cables, fibers or tubes.

    摘要: A waterproof splice for use in connecting two multiconductor electric cables having jackets of different insulation material and a method of making the splice are disclosed. The splice consists of a mechanical electrical connection between the conductors, a mechanical bond formed on the insulation of one of the conductors and a sheath of insulation material molded over the splice and adjacent cables. The sheath bonds with the jacket of one cable and the mechanical bond formed on the insulation of the other cable. The mechanical bond is a seal ring of elastomeric material that is compressed between glands to move the seal ring into sealing engagement with the conductor. The disclosed splice is both strong and waterproof in spite of the poor bonding characteristics between the two different insulation materials on the two conductors. The splice is appropriate for cables having surface, subsurface and underwater applications and is specifically designed for use in conducting seismic surveying operations.

    摘要: A method for providing substantial protection and insulation for submarine cable joints without utilizing costly molding and x-ray equipment. A heat shrinkable polyolefin protective covering includes an unexpanded conical transition between two expanded cylindrical portions. The unexpanded conical transition precisely locates the protective covering against a conical portion of a submarine cable jointbox. Polyamide adhesive is applied to the inside surfaces of the protective covering. During the application of heat to the protective covering, insubstantial relative movement between the conical transition portion of the protective covering and the locating portion of the jointbox allows proper alignment of the protective covering as the expanded cylindrical portions shrink and move relative to the jointbox. The diameters of the cylindrical portions of the protective covering are selected such that a nominal hoop stress is created during heating to minimize air entrapment and voids in the adhesive. Two protective coverings are overlapped to maximize the dielectric strength of the coverings, and to increase the path length for water egress into the joint.
