PROBLEM TO BE SOLVED: To provide an optical transmission/reception device that does not restrain wavelength selection at the time of transmission and reception while miniaturizing the device.SOLUTION: An optical transmission/reception device comprises: different output ports; a wavelength variable light source comprising wavelength variable lasers connected with the respective output ports; an optical modulator that is connected with one of the output ports, modulates light with first wavelength from the wavelength variable light source, and outputs the light after the modulation as a first optical signal; an optical receiver that is connected with the other of the output ports, and receives light with second wavelength from the wavelength variable light source by making it interfere with a second optical signal input from the outside; and a control unit that causes the wavelength variable laser to output the light with first wavelength and the light with second wavelength different from the first wavelength at the same time.SELECTED DRAWING: Figure 1 |
