Abstract
In order to determine a connection state of an optical fiber that connects a transmitting terminal and a plurality of receiving terminals, a test signal having a wavelength corresponding to a wavelength of an optical signal capable of being received at one receiving terminal among the plurality of receiving terminals is generated by clipping a portion of amplified spontaneous emission light. The generated test signal is transmitted through the optical fiber. Optical power of the test signal is detected at the one receiving terminal. The connection state of the optical fiber is determined based on a detection result of the optical power of the test signal.
