ABSTRACT:
An optical amplification relay transmission system containing, on a transmission line, an optical repeater for amplifying and relaying an optical signal. The object of the present invention is to perform monitoring of the optical transmission line and optical repeater in a short time and to make the construction of the optical repeater simple. The terminal station contains means for transmitting a burst optical signal on a first optical transmission line, and receiving the burst optical signal transmitted back through a second optical transmission line. Each optical repeater contains a first optical coupler for branching the above burst optical signal transmitted through the first optical transmission line, and a second optical coupler for making the branched burst optical signal, flow through the above second optical transmission line.
