Abstract: Optical fibers are embedded within the center portions of the male and the female elements of the connector. The tail ends of the embedded optical fibers exit the male and female elements on corresponding side portions thereof. The one ends of the optical fibers are disposed such that when the male and female elements are mated to establish electrical contact, the other ends of the optical fibers embedded within each element become properly aligned and are brought into contact thereby providing a path for a light signal to pass between them. A light source applied to one of the tail ends of the optical fibers exiting either of the electrically connected elements will then pass to the tail end of the optical fiber exiting the other element, thereby evidencing that the electrical connection between the elements is good.
