Changzhou Myway Electronics Co.,Ltd.

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. The present invention relates to an otdr which performs fusion splicing of optical fibers using an arc discharge.

To reduce a splice loss in fusion splicing of optical fibers by the optical power meter it is important to optimize the amount of heat applied to the optical fibers. In the optical fiber fusion splicer which utilizes discharge heating, there is provided a function to set the amount of heating by adjusting the discharge current.
