Abstract

PURPOSE:To obtain a necessary DU ratio at a receiving terminal which succeeds a data station, by monitoring the optical reception output of the data receiving terminal and by controlling the optical transmission power of data to be mixed newly by the monitoring output. CONSTITUTION:A data transmitting station 10 converts data to be transmitted into an optical signal and transmits it, and a data transmitting and receiving station 53 are cascaded through one or plural optical transmission lines 11a which transmits data from another station. An optical signal from this station 53 is transmitted to a data receiving station 24 through an optical transmission line 11b. Then, the optical reception output of the data receiving station 24 is monitored by a part 41, and the optical transmission power of data transmitted from the optical transmission line 11 to be mixed newly is controlled by the monitor 41.
