Abstract
An object is to provide a highly versatile optical fiber local-light detection apparatus capable of supporting various types of coated optical fibers. An optical fiber local-light detection apparatus according to the present invention includes: a first jigincluding a recess portioncurved along a longitudinal direction with respect to a coated optical fiberand a light input/output unitconfigured to emit light to the coated optical fiberthat is bent and to receive light leaking from the coated optical fiber a second jigincluding at least one protrusion portionthat is curved along the longitudinal direction with respect to the coated optical fiber, the second jig configured to clamp the coated optical fiberwith the recess portionof the first jig, in accordance with a type of the coated optical fibera pressing portion configured to apply pressing force in a direction in which the recess portionof the first jigand the at least one protrusion portionof the second jigmutually approach, to bend the coated optical fiber; anda switching mechanism configured to switch the at least one protrusion portionto a protrusion portion corresponding to the type of the coated optical fiber
