A coaxial cable/fiber optic bus network utilizes a coaxial cable for the main signal bus in a distribution system. The tap samples the electrical signal, and transforms the signal into a light pulse output. An optical splitter changes the single light output into a multiple output for serving a maximum number of peripheral units. Similarly, the input port on the tap uses a like optical splitter to recombine signal paths from the peripherals, in driving the coaxial line. Circuitry for incorporation in the tap provides a matching impedance when driving the coaxial line, and a high impedance on the line during the off-time in order to reduce line loading.

The present invention relates to contact surfaces on contact elements such as found in card edge connectors and the like. More particularly, the invention teaches a clip slideably mounted on the upper end of a contact element and providing a fixed, tin to tin contact area between the trace on a circuit card and the clip and a gold to gold sliding contact area between the clip and the contact element.
