摘要 |
The invention concerns an amplifier circuit for receiving an optical signal. The circuit comprises a light sensitive member ( 301 ) which delivers an electric signal in response to an optical signal. Furthermore, the amplifier circuit comprises an amplifier unit ( 302 ) with a first input ( 304 ) which receives an electric signal from the light sensitive member ( 301 ). The amplifier unit ( 302 ) is of the kind which does not have any special input intended for controlling the amplification. A filter unit ( 310 ) prevents a possible direct current from the light sensitive member ( 301 ) from reaching the first input ( 304 ). A control unit ( 314 ) is connected to the first input ( 304 ) for controlling the amplification of the circuit. The invention also concerns an optical communication system comprising an amplifier circuit of the above-described kind. The invention also concerns a method of controlling the amplification in an optical input stage. |
