摘要： A modulating apparatus modulates data to be transmitted according to a predetermined modulating system and generates a modulated wave, so that an optical device is driven by the modulated wave and a light-modulated wave is transmitted. As a result, an optical data communication can be realized. Since the optical device has non-linearity, a cross modulated wave is generated by the modulation of the data. However, if a carrier frequency is chosen so that the cross modulated wave does not enter a frequency band for transmitting the data, the problem of the cross modulated wave can be removed and data transmission without distortion can be achieved. The cost can be low if an LED is utilized as the optical device. Also, high-speed data transmission is possible if a multi-value modulating system is utilized.
摘要翻译：调制装置根据预定的调制方式对要发送的数据进行调制，生成调制波，由调制波驱动光器件，并传输光调制波。结果，可以实现光学数据通信。由于光学器件具有非线性，所以通过数据的调制产生交叉调制波。然而，如果选择载波频率使得交叉调制波没有进入用于发送数据的频带，则可以去除交叉调制波的问题，并且可以实现没有失真的数据传输。如果使用LED作为光学器件，则成本可能很低。此外，如果利用多值调制系统，则可以进行高速数据传输。
