Abstract:
1. An optical communications device for generating optical signals for data communication, the generated optical signals having a wavelength, which is shorter than a wavelength of optical signals for video signal communication, and which is adjacent to the wavelength of the optical signals for video signal communication, the optical communications device comprising: a packet-signal generator that generates packet signals as the optical signals for data communication; a dummy packet-signal generator that generates dummy packet signals to be inserted between the packet signals generated by the packet-signal generator; an idle-signal generator that generates idle signals to be inserted between a packet signal generated by the packet-signal generator and a dummy packet signal generated by the dummy packet-signal generator; and a switching controller that causes a dummy-packet signal generated by the dummy packet-signal generator and an idle signal generated by the idle-signal generator to be alternately transmitted, wherein the dummy packet-signal generator generates a dummy packet as a signal having a period longer than that of an idle signal generated by the idle-signal generator.
