Filed: 1993-10-15
Abstract: PURPOSE:To provide the optical submarine repeater which can execute magnetic grappling in an arbitrary section without being accompanied with application of a reverse current to a power feeding conductor. CONSTITUTION:A remote controller outputs an AC signal output operation start instructing signal to the optical submarine repeater 1 through a transmission line 6-1. A control signal detector 15 detects its signal and starts an output of an oscillator driving instruction 16. An AC oscillator 17 receives its instruction 16 and starts an oscillating operation. An AC signal component is superposed on a feeding current flowing through a power feeding conductor 4. In the vicinity of an optical submarine cable 2, an AC magnetic field is generated. By utilizing the AC magnetic field, magnetic grappling is executed. When the magnetic grappling is finished, the remote controller outputs an end instructing signal of the AC signal output operation. The control signal detector 15 detects its signal and finishes the output of the oscillator driving instruction 16. The AC oscillator 17 finishes the oscillating operation.
