In order to develop a light and small sized fusion splice machine operating from a small battery, a new high frequency discharge method with high voltage trigger has been developed. The method uses a high voltage trigger at the beginning of discharge to reduce power consumption. It was found experimentally that the voltage of an A-C discharge depends vastly on the applied voltage waveform. To use a high voltage trigger method effectively, pertinent applied voltage conditions were found considering the ion movement. By adopting pertinent conditions, the power consumption for discharge reduces to 1/5 of that for the conventional discharge method. The new method is adopted for developing a fusion splice in optical fibers. The developed machine is 2.5 kg in weight including battery, and consumes 25 watts electric power. The average splice loss and splice tension strength are 0.03 dB and 480 g, respectively.
