exposed to connect to other circuitry fig2 indicates in phantom lines an external circuit board 52 which has signal processing circuitry which may include an amplifier modulator demodulator etc to process electrical currents received from the contact 46 and or to generate electrical currents to deliver to the contact 46 to energize the transducer 40 the particular optoelectric connector is shown as having four optoelectric assemblies 61 64 although one or any number can be used the mating optical fiber connector 14 includes a ferrule 70 in which the cable optical fiber 24 is mounted with the tip 72 of its fiber being even or flush with the tip of the ferrule it would be possible to construct the optoelectric connector 12 so it received the ferrule 70 with the tip 72 of the optical fiber positioned close to the optic face 42 of the transducer 40 however the transducer 40 has a face of much larger width than the width of the optical fiber 24 as a result light from the fiber 24 would not be distributed over a substantial area of the transducer 40 so that only a very weak current would be produced by the transducer for moderate amplitude light in the optical fiber 24 also where the transducer 40 is designed to generate light that is to travel through the fiber 24 very little light generated by the transducer 40 would find its way into the fiber 24 in accordance with the present invention applicant provides an optical fiber stub 80 with an outer stub end 82 that is.
