An optical cable tracing system is constructed using an optical/electrical (hybrid) cable 10 containing both optical and electrical transmission media. This cable provides desirably high bandwidth via optical fibers 15 while connection accuracy is provided via electrical wires 13, which are used to operate indicator lights 941 at one or both ends of the cable. A hybrid plug connector 300 terminates the cable at each end and includes a dielectric housing 20, 30 that encloses the optical fiber (glass or plastic), which extends through a front opening 21 in the housing. A single cantilever latch 22 is mounted on a top-side of the housing that is adapted to engage a mating jack receptacle 440 in a locking relationship. A conductor-holding apparatus is molded into the bottom side of the housing where it holds a number of insulated electrical conductors and metallic blade terminals 36 that pierce the insulation and make electrical contact with each of the conductors. The mating jack receptacle includes a row of spaced wire springs 449 at the entrance of the optical connecting portion of the receptacle. The wire springs either extend to an opposite side of the receptacle to provide electrical interconnection between a pair of hybrid plug connectors, or the wire springs are arrayed to fit into a printed wiring board 710 for interconnection with electrical circuitry 730 thereon.
