Abstract: An optical fiber connector includes a ferrule with an interior splice chamber. A fiber stub is installed in the ferrule in a factory operation with one end in the splice chamber. The ferrule also includes permanent, opposed electrodes with tips at the walls of the splice chamber. To attach the connector to an optical cable in a field operation, a predetermined length of insulation is stripped from the end of the cable and the bare fiber is inserted into the splice chamber through a bore in the ferrule. Voltage is applied across the electrodes to create a plasma arc in the splice chamber. The plasma arc melts and fuses the adjacent ends of the cable fiber and fiber stub.
