PURPOSE:To suppress connection loss below a targeted value at all times by measuring the quantity of a relative axis shift between optical fiber end parts to be connected and adjusting the heat time of a connection part according to the shift quantity. CONSTITUTION:The tip parts of the optical fibers 1 and 2 to be connected are irradiated by a light source 7 and a transmission image is photographed by a CCD camera 10 through a magnifying lens 8. The transmission image is converted into a video signal, which is sent to an image processing part 11 and converted into a binary value, then the relative axis shift quantity of the connection part is measured. This measured value is sent to a central control part 12 to retrieve the shortest discharge time corresponding to the axis shift quantity from a discharging time map stored previously in a ROM and a specific discharging voltage is applied to discharging electrodes 6a and 6b through a discharging control part 13. Consequently, even if an initial shift quantity is large, the connection is made with lower loss than the targeted value. |
