Abstract
A transmission device includes: a wavelength-variable light source; a wavelength stabilized light source: a wavelength measuring device; a control circuit that controls the wavelength-variable light source; and a reception circuit that receives second reference wavelength light generated based on first reference wavelength light output from the wavelength stabilized light source whose wavelength stability is higher than that of the wavelength-variable light source, the control circuit calibrating the wavelength measuring device by using the second reference wavelength light, the control circuit calibrating the wavelength-variable light source by using the calibrated wavelength measuring device.
