The combination of an adaptor and a male connector are configured for screwing onto a female optical fiber connector consisting of electrically conductive material electrically connected to a sense node of a controller. A ground clip partially surrounds but is electrically isolated from the female connector. An adaptor consisting of an insulator ring having a first ring of electrically conductive material on a front face, a second ring of electrically conductive material on a back face, and a resistor mounted in a transverse groove of the insulator ring, with the resistor having its ends electrically connected between the first and second electrically conductive rings. The insulator includes a threaded centrally located hole for screwing onto the female connector, whereby the first ring is secured against the ground clip to ground the associated end of the resistor. A male connector having an electrically conductive housing is configured for carrying an optical fiber holder that plugs into a cylindrical cavity of the female connector when the male connector is screwed onto the female connector, with a front face of the male connector mechanically and electrically engaging the second ring to electrically connect the other end of the resistor to the female connector, whereby the controller responds by permitting activation of an associated laser transmitter to transmit laser light into an optical fiber carried by the optical fiber holder.
