Claim 2:
3. The optical transmission device of claim 2, wherein the control module comprises:
a slope controller which connects the multi-level pulse amplitude modulator, and generates the slope adjust signal according to the polarity of the input signal of the dispersion amount, and generates and outputs the polarity adjust signal to the multi-level pulse amplitude modulator according to the slope adjust signal;
a bias voltage offset controller which generates the bias voltage offset adjust signal according to the magnitude of the dispersion amount of the input signal;
an optical modulator bias voltage controller which connects the asymmetrical optical modulator, the slope controller and the bias voltage offset controller, receives the slope adjust signal and the bias voltage offset adjust signal respectively from the slope controller and the bias voltage offset controller, and generates and outputs the control signal output to the asymmetrical optical modulator according to the slope adjust signal and the bias voltage offset adjust signal; and
an electrical level adjustor which connects the multi-level pulse amplitude modulator and the bias voltage offset controller, and generates and outputs the electrical level adjust signal to the multi-level pulse amplitude modulator according to the bias voltage offset adjust signal.
