Abstract:
An optical fiber fusion splicer comprising: a V-shaped groove base that respectively fixes and clamps left and right optical fibers in a V-shaped groove and a clamp for fixing optical fibers in a V-shaped groove, an observation means for observing said left and right optical fibers from the side, a V-shaped groove movement mechanism that aligns the end surfaces of optical fibers by performing axial alignment of said left and right optical fibers based on observation information from said observation means, and electrodes that generate an electrical discharge at the aligned portions to fuse and join them;wherein, a V-shaped groove base vertical movement means is provided that moves said V-shaped groove base up and down so that the centers of the axes of said optical fibers are positioned at the proper location for electrical discharge corresponding to the magnitude of optical fiber diameter.
