Abstract

PURPOSE:To reduce respective current consumption by detecting the decrease in a voltage or a current fed from a transmission circuit to each reception side communication controller if a sender communication controller is subject to power failure and allowing each reception side communication controller to stop the operation of its own repeater. CONSTITUTION:If an AC input 9 is subject to power failure in a communication controller 3, when a DC voltage from a remote feeder 8 is a specified value or over, an operation instruction signal is being sent from a DC voltage detection circuit 311 to a DC-DC power supply 312 and a DC voltage is being supplied to an optical communication section 30. If the AC input 10 is subject to power failure, the DC voltage fed from a transmission line 42 to a reception circuit 31 is dropped and decreased more than the specified voltage, then the operation instruction signal to the DC-DC power supply 312 is stopped and the operation of the DC-DC power supply 312 is also stopped. When the AC input 10 is restored next, the said DC voltage rises, and when it exceeds the specified voltage, the operation command signal is sent from the DC voltage detection circuit 311 to the DC-DC power supply 312 to restore the supply of the DC voltage to the optical communication section 30.
