Abstract
An optical fiber fusion splicer includes positioning members and clamping members. Each clamping member clamps the bare fiber. A first guiding portion protrudes from the top surface of each positioning member and guides a distal end portion of the bare fiber toward the groove. A concave face of the first guiding portion has a V-shaped cross section. Each clamping member includes a second guiding portion, which guides a base portion of the bare fiber toward the groove of the corresponding positioning member, and a pressing member, which presses the bare fiber against the top surface of the fiber positioning member. A concave face of the second guiding portion has an inverted-V-shaped cross section. The fusion splicer can clamp bare fibers while the bare fibers are received by the groove.
