A housing case for a fusion splicer is a housing case for housing the fusion splicer for an optical fiber. The housing case for a fusion splicer includes a case main body including a first side wall, and a lid body attached to the case main body to be openable and closable. The lid body includes a second side wall configured to match the first side wall when closed. At least one of the first side wall and the second side wall includes an insertion portion configured for a cable extending from the inside of the housing case to the outside thereof to be inserted through the insertion portion in a state where the lid body is closed with respect to the case main body.

A fusion splicer includes an irradiation unit to irradiate an optical fiber with first wavelength light and second wavelength light; a light receiving unit; a processing unit to extract first feature data from first luminance information based on the first wavelength light and to extract second feature data from second luminance information based on the second wavelength light; a determination unit to determine whether the first feature data and the second feature data are within a predetermined range; and a drive unit to move one optical fiber on the basis of the luminance information from which the feature data is extracted so as to arrange the axes of the optical fibers in a predetermined positional relationship when the feature data is determined to be within the predetermined range. The processing unit extracts the second feature data when the first feature data is not within the predetermined range.

Optical fiber fusing and connecting machine and optical fiber fusing and connecting method

A splicer and a method for fusion-splicing optical fibers are provided, in which the disconnection of a fusion spliced portion of optical fibers can be prevented when the windbreak cover is opened upon fusion splicing. A method for fusion-splicing optical fibers includes: holding optical fibers on optical fiber holders which are arranged on a pair of movable stages, respectively and covering the holders with a windbreak cover; and butting the optical fibers each other by bringing the pair of movable stages mutually closer; fusion-splicing the butted optical fibers together; and loosening, before opening the windbreak cover, the tension applied to optical fibers between the fiber holding parts and positions at which the windbreak cover contacts with the optical fibers.
