Abstract
The signal relay apparatus has a plurality of photoelectric converters which convert an optical signal input from an electronic equipment (A-C) into an electric signal and outputs the same to the photoelectric converter (-), and which converts an electric signal input from another photoelectric converter and outputs the same to the corresponding electronic equipment; a plurality of switch circuits (-) which are provided at input and output ends of the electric signal of the photoelectric converter (-) and which are opened and closed to bypass the electric signal; and a power source supply section (-) which supplies a power source to the electronic equipment connected to the photoelectric converter. In a first J/B () and a second J/B (), when any one of the electronic equipments connected to the photoelectric converters is not used, the electronic equipment (A-C) is bypassed by the switch circuit, and the power source supply section stops the supply of a power source to the electronic equipment (A-C).
