ABSTRACT:
An optical receiver comprises a photodiode (1) which is connected to a biasing circuit (2), and also to the output (14) of the receiver via the series arrangement formed by a preamplifier (3), a control amplifier 4 and an output amplifier (5), the output of the receiver being connected to the control input 10 of the control amplifier (4) via a detector (6) and a differential amplifier (9). The control amplifier (4) is what is commonly referred to as a differential controller, in which alternating current and direct current are processed in the same manner. As a consequence thereof, it is possible to determine the optical input level of the receiver continuously at the output of the control amplifier by means of a simple ammeter (8).
