PURPOSE:To improve insulation among respective packages and devices and to improve reliability at connection/disconnection to/from a bus device by constituting the bus device interconnecting packages and devices with a optical circuit. CONSTITUTION:An optical bus device is provided with 6 star couplers (SC) 10a-10f, each of which is provided with 7 optical signal paths and an optical fiber 11 is connected at optical signal communication. An optical connector is connected to a tip of the optical fiber 11. An optical signal path of the optical star coupler 10a and forms a 1st bit common bus line, the optical signal path of the optical star coupler 10b forms a 2nd bit common bus line,..., and the optical signal path of the optical star coupler 10f forms the 6th bit common bus line. Since the bus signal line is formed by the optical circuit, even when the electronic circuit package is inserted or detached in the active line state, since the insulation is excellent, the adverse influence onto other electronic circuit package due to noise is avoided. |
