Abstract:
1. An optical fiber fusion splicer comprising a pair of bare fiber holding members and splicing means, the pair of bare fiber holding members fixing in place bare fibers that are located in distal end portions of optical fibers and not covered by resin coatings, the splicing means fusion-splicing the bare fibers fixed in place by the bare fiber holding members together, wherein each of the bare fiber holding members includes a fiber positioning member including a fiber groove and a first concave guiding portion on a top surface of the fiber positioning member, the fiber groove receiving a corresponding one of the bare fibers, the first concave guiding portion protruding from the top surface of the fiber positioning member and guiding the bare fiber toward the fiber groove, and a fiber clamping member including a second concave guiding portion and a pressing member, the second concave guiding portion having an inverted V-shape, the second concave guiding portion guiding toward the fiber groove a portion of the corresponding bare fiber positioned closer to a base of the bare fiber than a portion of the bare fiber guided by the first concave guiding portion, the pressing member having a lower end that protrudes downward lower than an apex of the inverted V-shape of the second concave guiding portion, the pressing member pressing the bare fiber against the top surface of the fiber positioning member while the bare fiber is received by the fiber groove.
