In order to determine the connection state of an optical fiber that connects a transmitting terminal and a plurality of receiving terminals, a test signal having a wave length corresponding to the wave length of an optical signal capable of being received at one of the receiving terminals of the plurality of receiving terminals is generated by way of cutting a portion of amplified spontaneous emission light, the generated test signal is transmitted to the optical fiber, the optical power of the test signal is detected by the one receiving terminal, and the optical fiber connection state is determined on the basis of the detection results for the optical power of the test signal. |
