[Problem] To provide an optical communication device and the like with which the optical signals output by multiple light output units can be set with an accurate wavelength interval. [Solution] An optical communication device equipped with: multiple light output units that output optical signals of mutually different wavelengths; a multiplexing unit that outputs a wavelength-multiplexed signal by multiplexing the multiple optical signals output from the multiple light output units; a reference light output unit that outputs reference light serving as a reference; a wavelength generation unit that, on the basis of the reference light, outputs multiple light beams having a wavelength interval in accordance with a prescribed frequency; and a wavelength control unit that controls the wavelength of the optical signals output by the light output units in accordance with the interference component between the wavelength-multiplexed signal and light with the wavelength of at least one of the multiple light beams. |
