ABSTRACT:
An optical receiver for suppressing a useless intensity modulation component having an optical to electrical converter for converting an optical main signal to an electrical signal, an identifying device for identifying the electrical signal converted in the optical to electrical converter, an optical amplifier for amplifying the optical main signal provided on a preceding stage of the optical to electrical converter, an electrical amplifier for amplifying the converted electrical signal for a main signal provided on a rear stage of the optical to electrical converter, and a capacitor coupled on the preceding stage of the electrical amplifier having a characteristic of a low cut-off frequency higher than a polarization scrambling frequency or a monitoring control signal frequency.
