    摘要: An optical transmission system according to the present invention includes a connection confirming circuit 106 for confirming connection of an input data signal, a test signal generator 105 for generating a test signal, and a switching device 107 on a transmitter side. The switching device 107 selectively generates the input data signal from an output terminal in the case where the input data signal is detected by the connection confirming circuit 106, and the test signal when the input data signal is not detected. An output of the switching device 107 is connected to an optical transmitter TX. On a receiver side, there is provided a determination circuit for receiving an optical signal from a transmission path and detecting the test signal to determine transmission characteristics of the transmission path on the basis of the test signal.
