摘要： An optical transmitter includes an equalizer which receives a data signal, an optical modulator driver which amplifies an output signal of the equalizer, and an optical modulator which converts an output signal of the optical modulator driver into an optical signal and outputs the optical signal. The equalizer has a signal line for transmitting the data signal, a coupled line electromagnetically coupled to the signal line, a resistive section connected to the coupled line, and a ground via connected to the resistive section. The equalizer reduces power of the data signal in a frequency range where the frequency response characteristic of the optical modulator driver exhibits peaking, to reduce waveform jitter in the output signal of the optical modulator driver that is input to the optical modulator.
