Optical fiber testing device

The utility model discloses an optical fiber testing device. The optical fiber testing device comprises a base, and a wire clamping device, an illuminating lamp, an industrial camera and a driving mechanism which are arranged on the base, wherein the wire clamping device is used for clamping and fixing an optical fiber; the illuminating lamp is used for providing a light source required by stable imaging of the optical fiber; the industrial camera is arranged on a light path of the light source and is used for capturing imaging light passing through one end of the tangent plane of the optical fiber; and the driving mechanism is used for driving one of the wire clamping device, the illuminating lamp and the industrial camera to move, so that the industrial camera captures images of all angles of the section of the optical fiber. The multi-angle detection image of the optical fiber cutting end face can be accurately obtained, and the optical fiber cutting angle detection efficiency is improved. 本实用新型公开了一种光纤测试装置
