Abstract : The patent application concerns a receiver for use with a photodiode in an electro-optical transmission line. First and second amplifier circuit channels are connected to an output port of a photodiode. One channel is provided with a wide-bandwidth amplifier for amplifying the high frequency portion of a signal from said output signal port and a second channel is provided with a low frequency amplifier for amplifying direct current and the low frequency portions of the signal from said output signal port. The outputs of the wide-bandwidth amplifier and the low frequency amplifier are combined to provide a composite output signal which is an amplified replica of the output of said photodiode. This receiver amplifier configuration is optimized for use in avionics applications. The use of short lengths of medium loss fiber, LED source diodes, and PIN photodiodes is assumed.
