    • PURPOSE:To prevent mission of data when bypass of a station is switched during the operation of the system and to eliminate the adverse effect exerting on other stations, by providing a control means controlling the intensity of an optical reproducing output of an optical reproducing repeating installation to an optical data station. CONSTITUTION:An optical input is branched into two at an optical branching device 501 of an optical data station 500, one branched signal is inputted to an optical delay device 514 and the other optical reproducing relay device 503. The device 503 is controlled with a controller 517 connected to a power supply 518 of a power supply device. The device 503 is provided with an photoelectric conversion circuit 505, an AGC circuit 506 making the output amplitude of the circuit 505 constant, and an optical output adjusting circuit 509, etc. controlling the intensity of light of an optical after amplification and reproduction. The device 517 keeps the order of control of the device 516 and the circuit 509 in a prescribed order, allowing to prevent missing of data when the bypass of the station is switched during the operation of the system and to eliminate the adverse effect exerting on other stations.
