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 jig 11 including a recess portion 22 curved along a longitudinal direction with respect to a coated optical fiber 100 and a light input/output unit 14 configured to emit light to the coated optical fiber 100 that is bent and to receive light leaking from the coated optical fiber 100; a second jig 12 including at least one protrusion portion 23 that is curved along the longitudinal direction with respect to the coated optical fiber 100, the second jig configured to clamp the coated optical fiber 100 with the recess portion 22 of the first jig 11, in accordance with a type of the coated optical fiber 100; a pressing portion configured to apply pressing force in a direction in which the recess portion 22 of the first jig 11 and the at least one protrusion portion 23 of the second jig 12 mutually approach, to bend the coated optical fiber 100; and a switching mechanism configured to switch the at least one protrusion portion 23 to a pr…
