ABSTRACT:
An optical fiber fusion splicer includes a discharge unit for producing an electric discharge to fusion splice optical fibers and a pressure sensor for producing a pressure detection signal representing the surrounding atmospheric pressure. In response to the pressure detection signal the discharge is controlled by a control unit so that a substantially optimum discharge current for the fusion splicing is provided to the discharge unit. The discharge control unit includes an adjusting unit for producing a discharge current adjusting signal, a control signal generating unit for generating a control signal on the basis of both the pressure detection signal and the discharge current adjusting signal, and a discharge current control unit for controlling the discharge current in response to the control signal.
