Abstract

An optical transmission device includes: a plurality of optical transceivers; a wavelength selective switch; and a controller configured to control the plurality of optical transceivers and the wavelength selective switch. Each of the optical transceivers includes a wavelength tunable light source. The controller controls a wavelength of a wavelength tunable light source of a selected optical transceiver according to a wavelength of an optical signal received by the destination remote device. The controller controls the wavelength selective switch so as to generate the WDM optical signal from a plurality of optical signals generated by the plurality of optical transceivers, and to guide the plurality of optical signals received from the plurality of remote devices to the plurality of optical transceivers according to wavelengths of the received plurality of optical signals.
