摘要 |
An optical receiver circuit comprising an optical converter circuit ( 38 ), comprising a photodiode and converting optical power into electrical power, a sensor circuit for deriving a control voltage VCONTR as a characteristic value of the electrical power output by the optical converter circuit ( 38 ); and an attenuator circuit ( 44 ) having a variable attenuation, the attenuation being controlled by the characteristic value of the electrical power output by the sensor circuit so as to obtain a constant output signal level of the optical receiver circuit. An output circuit is also provided and comprises a matching network ( 46 ), an amplifier stage ( 48 ) and an output transformer ( 50 ). |
