Abstract
Disclosed is a method of fusion splicing single-mode optical fibers, in which an offset distance D, between the axes of the optical fibers subjected to fusion splicing, is measured when the axes of the cores of the optical fibers are aligned with one another. The arc discharge time, current and/or energy is determined according to the measured distance D.
