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.
Claims4
A fiber optic connector comprising:
- (a) a ferrule having walls defining an interior splice chamber and first and second bores forming fiber-receiving paths extending from the splice chamber to first and second exterior points on the ferrule surface;
- (b) a fiber stub secured within the first bore and extending from the first exterior point into the splice chamber;
- and
- (c) splice electrodes permanently mounted in the ferrule walls and having inwardly extending tips defining an arc gap within the splice chamber, said electrodes being connectable to a voltage source for creating a plasma arc at the gap capable of fusing one end of the fiber stub to one end of a cable fiber guided into the splice chamber through the second bore.
