Abstract: An electrical connector (30) having crosstalk reduction between selected pairs of electrical contacts comprises a printed circuit board (36, 36') having a pair of circuit elements (40, 42) therein connected through welding pads to selected contacts (6, 3) the connector. The signal paths of such selected contacts are severed and then are re-routed by means of the pattern of circuit elements in the printed circuit board, each circuit element balancing the mutual inductance in such re-routed signal paths for enhanced crosstalk reduction.

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.
