ABSTRACT:
A method for detecting trouble occurring in a single-fiber two-way optical transmission system containing first and second optical terminal stations connected to each other through at least one two-way single optical fiber. A first abnormality in a first optical signal received at the first optical terminal station is detected. A notice that the first optical terminal station will stop transmission of optical signals, is transmitted from the first optical terminal station to the second optical terminal station after occurrence of the first abnormality is detected. Transmission of optical signals from the first optical terminal station is stopped after transmission of the notice. An abnormality in an optical signal next received at the first optical terminal station is detected after the stopping of the transmission of optical signals from the first optical terminal station.
