ABSTRACT:
In an optical communications device that generates picture optical signals and optical signals for data communication by wavelength division multiplexing, it is carried out to alter a signal pattern inserted between packet signals of the optical signals for data communication so that a frequency component of a modulation waveform of the signal pattern disperses. The signal pattern is generated by inputting outputs of a counter for counting up a sign bit into a coder adopting a designated coding method.
