    摘要： An optical fiber splicer for splicing a plurality of first optical fibers arranged in spaced relationship with each other and a plurality of second optical fibers arranged in opposed relationship with the first optical fibers. The optical fiber splicer includes an XY table movable in XY directions orthogonal to each other, a tray mounted on the XY table, and first and second clamps for respectively clamping a selected one of the first optical fibers and a selected one of the second optical fibers to be spliced to the selected first optical fiber. The optical fiber splicer further includes first and second electrodes extending vertically and aligned with each other, first and second cameras located so as to interpose the first electrode, and an image processing unit for processing images picked up by the first and second cameras.

    摘要： An optical fiber edge surface processing method has the steps of capturing a transmitted-light image of end portions of two optical fibers placed facing each other, and extracting, based on a brightness distribution in the transmitted-light image, edge surface information of each of the two optical fibers to be spliced together; selecting a discharge condition corresponding to the edge surface information from among a plurality of discharge conditions prestored in a storage unit; and melting the splicing edge surfaces of the two optical fibers in accordance with the selected discharge condition, and thereby shaping the splicing edge surfaces. With this method, splice loss can be reduced in a simple manner, even when the edge surface angle of each optical fiber, or the relative edge surface angle between the two optical fibers, or the amount of chipping at the splicing cross section of each optical fiber, is large.
