摘要

There are provided a discharge unit (2) for producing an electric discharge to fusion splice optical fibers and a pressure sensor (6) for producing a pressure detection signal representing the surrounding atmospheric pressure. In response to the pressure detection signal, a discharge control unit (3) controls the discharge so that a substantially optimum discharge current for the fusion splicing is provided to the discharge unit (2).
