Claim Text:
1. An optical transmission system comprising: a first optical modulator that performs an optical modulation process for input light; a second optical modulator that performs an optical modulation process for the input light; a third optical modulator that performs an optical modulation process for the input light; signal output unit that outputs a drive signal according to an input signal to the first optical modulator; first waveform shaping signal output unit that outputs a first waveform shaping signal to the second optical modulator; and second waveform shaping signal unit that outputs a second waveform shaping signal to the third optical modulator, wherein the first waveform shaping signal output unit outputs the first waveform shaping signal at a timing relatively later than a timing of an output of a signal by the first optical modulator, and the second waveform shaping signal output unit outputs the second waveform shaping signal at a timing relatively earlier than the timing of the output of the signal by the first optical modulator.
