The method comprises the steps of preparing a guide with V-shaped grooves, securing at least one optical fiber element on the surface of the guide, bridging and fixing the guide on the stationary and movable support members, and separating the guide along at least a line extending between the stationary and movable support members. Thus, the guide and the optical fiber element is separated into a first part supported by the stationary support member and a second part supported by the movable support member, to constitute the optical switch having at least one pair of optical fibers.

    摘要： A duplexer of the present invention includes a reception filter (3) for passing signals in a predetermined frequency band and attenuates signals in the other frequency bands among reception signals input to an antenna port, and a transmission filter (4) for passing signals in a predetermined frequency band and attenuates signals in the other frequency bands among transmission signals input from the outside and outputting them to the antenna port. The duplexer further includes a conversion circuit (22) provided with a single-ended input terminal connected to the antenna port and balanced output terminals. The reception filter (3) is provided with a balanced input terminal connected to the output terminal of the conversion circuit (22) and a balanced output terminal for outputting the filtered reception signal. Thus, a balance-output-type duplexer that is connectable to a balance-input-type LNA and is free from loss and degradation in power-handling capability, a communication module and a communication device can be realized.
