Abstract
An optical fiber splicing method capable of fully reducing the splice loss at room temperature is provided. In the optical fiber splicing method in accordance with the present invention, respective end faces of optical fibers are fused together in a splicing step (S101). In a condition setting step (S102), a set value &agr;0 is set. Thereafter, a heating step (S103), a measuring step (S104), and a termination determining step (S105) are carried out repeatedly. In the heating step, a region including the fusion-spliced point is heated under a predetermined heating condition. In the measuring step, splice loss is measured. In the termination determining step, the splice loss &agr;n measured in the measuring step and the set value &agr;0 set in the condition setting step are compared with each other in terms of magnitude. If the splice loss &agr;n is not greater than the set value &agr;0, then it is determined that the alternation should be terminated, whereby the optical fiber connecting operation is terminated.
