Abstract

First data and second data are transmitted by a simple configuration by including a generation unit that generates a wavelength-changed signal on the basis of the second data, and a transmission unit that transmits the wavelength-changed signal together with a first signal that indicates the first data.

First claim

What is claimed is:

1 . A communication control device that transmits first data and second data, the communication control device comprising:
a generation unit that generates a wavelength-changed signal on the basis of the second data; and a transmission unit that transmits the wavelength-changed signal together with a first signal representing the first data.

2 . The communication control device according to claim 1 , wherein
the generation unit includes an application unit that applies wavelength change according to the second data to a clock signal, and the transmission unit superimposes the clock signal to which the wavelength change has been applied to the first signal and transmits the superimposed signal.

3 . The communication control device according to claim 2 , wherein
the generation unit includes a data conversion unit that creates a wavelength change control waveform signal on the basis of a second signal representing the second data, and an oscillation control unit that changes an output oscillation frequency according to the wavelength change control waveform signal.

4 . The communication control device according to claim 1 , further comprising:
a reception unit that receives the first signal and the wavelength-changed signal, and a restoration unit that restores the second signal from the received wavelength-changed signal.

5 . The communication control device according to claim 4 , wherein
the restoration unit creates a waveform signal according to deviation of frequency between the wavelength-changed signal and a reference signal, binarizes the waveform signal to generate a second signal representing the second data, and converts the second signal into numerical form to restore the second data.

6 . A communication control system including a first device and a second device, and in which the first device transmits first data and second data to the second device, wherein
the first device includes a generation unit that generates a wavelength-changed signal on the basis of the second data related to the first data, and a transmission unit that transmits the wavelength-changed signal together with a first signal representing the first data, and the second device includes a reception unit that receives the first signal and the wavelength-changed signal, and a restoration unit that restores the second data from the received wavelength-changed signal.

7 . The communication control system according to claim 6 , wherein,
in the first device, the generation unit includes an application unit that applies wavelength change according to the second data to a clock signal, and the transmission unit superimposes the clock signal to which the wavelength change has been applied to the first signal and transmits the superimposed signal.

8 . The communication control system according to claim 7 , wherein,
in the first device, the generation unit includes a data conversion unit that creates a wavelength change control waveform signal on the basis of a second signal representing the second data, and an oscillation control unit that changes an output oscillation frequency according to the wavelength change control waveform signal.
