摘要： A tray for fusion splicing work is a tray used for fusion splicing work for an optical fiber, and includes a tray main body and a first body contact member. The tray main body includes a pair of long wall portions extending along a first direction, and a pair of short wall portions extending along a second direction. The first body contact member includes an outer surface configured to come into contact with a body of an operator using the fusion splicer and is attached to the tray main body on a side of one long wall portion of the pair of long wall portions. The first body contact member is able to be transitioned between an unfolded state in which the outer surface is unfolded in a third direction and a housed state in which the first body contact member is housed from the unfolded state.

摘要： An optical fiber fusion splicing method for performing fusion splicing through positioning of optical fibers to be spliced in a V-groove is provided. The optical fiber fusion splicing method includes pressing the optical fibers placed in the V-groove relatively toward the V-groove using a clamp, varying a clamp pressure of the clamp pressing the optical fibers, and moving the optical fibers placed in the V-groove with respect to the V-groove in an axial direction.

摘要： 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.

摘要： This optical fiber alignment jig for aligning a plurality of optical fibers with the tip end coating stripped off to expose glass fiber includes a rail; a convex push-up part capable of moving in the extending direction of the rail; and a plurality of plate-shaped parts that each have a first surface and a second surface perpendicular to the extending direction of the rail and an inclined surface that can carry a respective optical fiber, the inclined surfaces of the plurality of plate-shaped parts being inclined, relative to the extending direction of the rail, in the same direction. The plurality of plate-shaped parts are arranged side by side along the extending direction of the rail with the first surface of one plate-shaped part facing the second surface of an adjacent plate-shaped part and are contacted by the push-up part so as to move toward the inclined surface side.
