  • Branching unit with reconfigurable terminal connections
    Patent number: 6987902
    Abstract: A branching unit integrated into a submarine telecommunication system comprising three cables having optical and electrical transmission members comprises three terminals connected to the electrical transmission members of the cables, three input points, and three electrical contacts each between one of the terminals and one of the input points. In an operating configuration, and at a given time, a first terminal and a second terminal are electrically connected together and form a trunk segment adapted to convey a trunk current, and a third terminal is electrically connected to a submarine ground to form a branch segment adapted to convey a branch current. The branching unit carries out reconfiguration by controlling switching of the electrical contacts. A voltage indicating the potential at a point on the trunk segment is measured. Because an optical reconfiguration request is made by means of an optical reconfiguration signal the unit is able to receive and process optical reconfiguration signals.
