摘要： PROBLEM TO BE SOLVED: To prevent occurrence of an instantaneous interruption even with the occurrence of a physical disconnection due to switching of optical fiber connection.SOLUTION: A bypass optical fiber 2 is a currently-used optical line optical fiber 1 using a pair of lateral light input-output mechanisms 3 and 3' inputting and outputting an optical signal to and from the currently-used optical line optical fiber 1. The bypass optical fiber 2 allows intervention of: an optical switching mechanism 5 for interrupting/opening the optical communication; an optical amplification mechanism 6 for amplifying the optical signal; and optical monitor mechanisms 8 and 8' for checking whether optical communication has been established via the bypass optical fiber 2. The currently-used optical line optical fiber 1 allows intervention of an optical temporary interruption mechanism 4 for temporarily interrupting the optical communication and a fiber disconnection mechanism 7 for disconnecting the currently-used optical line optical fiber 1. These individual mechanisms are controlled by a control device 10, which obtains, via a communication mechanism 11, a clock-time when no signal is transmitted from a station-side transmission device, and disconnects the optical fiber 1 at the clock-time.
