An optical fiber characteristic measuring device for automatically measuring, at successive measuring stages, various characteristics of optical fiber samples. Each measuring stage has optical system incident and emergent ends. An optical fiber sample is set in a carrier which moves from measuring stage to measuring stage. At each stage the set fiber sample is coupled to the incident and emergent ends of the stage and automatically subjected to the measurement to which the stage is dedicated. Bending units provide a desired degree of curvature to the fiber sample under test to control light propagation therein. |
