发明名称 Power feeding submarine telecommunications systems
摘要 An optical undersea telecommunications system has a main cable (1) which branches (BU1) near a landfall to two separate stations. Each branch (71,81) supplies half the current of the main cable (1) for powering the regenerators. In the event of a fault in a branch (e.g. 81) caused by an anchor or fishing gear, the operations branch (71) regenerator (e.g 11) can supply the full current (I) via a zener diode power feed and bypass circuit and high voltage diodes (D1,D2) automatically prevent leakage of current back to the fault.
