An apparatus for transmitting over optical cables a red image signal, a green image signal, and a blue image signal output from a personal computer, a clock signal indicative of the starting points of data frames of the image signals, an enable signal indicative of scan and blank periods of the image signals, a vertical synchronization signal and a horizontal synchronization signal. The apparatus includes a reference signal generator, a parallel-to-serial converter and a light signal generator. The reference signal generator generates a reference signal having predetermined data when the blank period starts in accordance with the enable signal. The parallel-to-serial converter converts the reference signal corresponding to the blank period and the image signals corresponding to the scan periods into serial signals. The light signal generator converts the clock signal, the enable signal, the vertical synchronization signal, the horizontal synchronization signal and the serial signals output from the parallel-to-serial converter into light signals to then be incident into the optical cables.
