る場合が多い。The conventional bypass relays mentioned above use an optical switch method and use mechanical and optical methods, resulting in high manufacturing and adjustment costs and, in principle, cannot amplify light intensity. Therefore, the optical fiber length is limited by the total length of the bypass. In other words, when a loop network is configured using optical fibers, the total length of the optical fiber that can be transmitted must be determined assuming that signal bypass occurs at each end station, and the Amplification devices are often required.

通信用バイパススイ・ソチを作成することができる。As explained above, in the present invention, by configuring a bypass switch using a power failure detection control circuit, the E/○ converter and the 0/'E converter can be operated even during bypass, so there is no need for a relay amplifier. An optical loop network can be constructed, and the structure is simple.
This has the effect of reducing manufacturing and adjustment costs. Further, the battery backup time can be determined depending on the use of the system, and an optimal optical communication bypass switch can be created depending on the use.
