Abstract

PURPOSE:To prevent a data way from being cut off even during a break of power supply, by forming a bypassing circuit for signals by using an optical switch made of an optical fiber which operates by being bent. CONSTITUTION:An optical switch 42 is made of an optical fiber which operates by being bent, and is off during the operation of an electronic device 11. A signal from an optical fiber 1 is sent to an optical fiber 2 through an optical branching device 40, an optoelectric converter 26, the electronic device 11, an electrooptical converter 27, and an optical branching device 41. Once the electronic device 11 is powered down, the optoelectric converter 26 and electrooptical converter 27 are also powered down, but a control line 43 operates to turn on the optical switch 42. Then, the optical signal from the optical fiber is sent through the optical branching device 40, optical switch 42, and optical branching device 41.
