| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an optical signal monitoring device which enables a visual conformation by branching and taking out a part of an optical communication signal from an optical transmission line as an optical signal for monitoring, and irradiating a visible light transducer with the taken-out optical signal, which can simply and easily monitor the transmission line and which has an excellent reliability and economy. SOLUTION: The optical signal monitoring device 1 comprises the optical transmission line for propagating the optical communication signal, the optical signal for monitoring by branching the transmission line for monitoring the transmission line, and a visible light transducer 7 for converting the optical signal into a visible light.
