Claims

[Scope of utility model registration request]

In an optical fiber distributor that optically couples a plurality of optical fibers and one or more optical fibers coaxially via a mixing rod, the tapered fused portion consisting of the plurality of optical fibers has a core rupture. An optical fiber distributor characterized in that the cross-sectional shape at least at a mixing rod connection position is formed to be circular without reducing the area.
