Abstract: A shielded optical fiber adaptor for mounting in an opening of a conductive faceplate of electronic equipment. The adaptor has an insulative body with a conductive plate imbedded therein. The plate has an aperture within the body which allows passage of light from the optical fiber and extends outwardly of the body to contact the faceplate when the body is retained in the faceplate opening. The largest dimension of the plate aperture is no more than ten percent of the wavelength at the highest operating frequency of the electronic equipment. In another embodiment, the plate is eliminated and the body is covered by a layer of conductive material. An interior channel in the body holds the fiber and has an aperture of no more than ten percent of the wavelength at the highest operating frequency of the electronic equipment. Since the interior of the channel is covered by the layer of conductive material, it acts as an attenuating waveguide.
