ABSTRACT:
Apparatus for testing multiple optical fibers comprises a light source, a light detector, a first set of adapter fibers, and a second set of adapter fibers corresponding on a one-to-one basis with the first set of adapter fibers. A first end of each fiber of the first set is held in a first fiber holding structure, and a first translation mechanism is provided for translating the first fiber holding structure relative to the light source so as to bring the first end of any selected one of the first set of adapter fibers into optically coupled relationship with the light source. A first end of each fiber of the second set is held in a second fiber holding structure, and a second translation mechanism is provided for translating the second fiber holding structure relative to the detector to bring the first end of any selected one of the second set of adapter fibers into optically coupled relationship with the light detector. A controller coordinates operation of the first and second translation mechanisms so that when the first end of an adapter fiber of the first set is in optically coupled relationship with the light source, the first end of the corresponding fiber of the second set is in optically coupled relationship with the light detector.
