ABSTRACT:
The present invention provides an optical receiver operable for optical signals each having different transmission speed. The optical receiver includes a light-receiving device, a pre-amplifier, a main amplifier, and a control circuit. The pre-amplifier, may be a trans-impedance amplifier, includes a parallel connection of a switching device and a resistor in a trans-impedance or a load element. By switching ON/OFF the switching device, the gain and the bandwidth of the pre-amplifier may be changed. By providing a filter circuit, whose cut-off frequency may be switched, in the main amplifier, the bandwidth of the optical receiver may be varied.
