ABSTRACT:
A fiber optic receiver of the type having a sensor, a pre-amplifier and a post-amplifier, includes a first printed circuit board with connection of the post-amplifier therewith and having a matable connector thereon for obtaining power for operation of the post-amplfier. A second printed circuit board is supported by the first printed circuit in intersecting geometric relation to the first printed circuit board and is electrically connected therewith for obtaining power for operation of the pre-amplifier. The pre-amplifier and the sensor are mounted on the second printed circuit board and are electrically interconnected thereon. The receiver further includes a channel for detecting the presence of the carrier of energy incident on the sensor incorporation a differential peak detector circuit. A transmitter may be incorporated to provide a fiber optic transceiver.
