Abstract
An expanded beam ferrule includes a first ferrule halve having reflective surfaces and a second ferrule halve, which together retain optical fibers. The reflective surfaces output light perpendicular to the mid-plane of the ferrule. A sleeve aligns the external surface of two similar ferrules, with the reflective surfaces of the respective ferrules facing each other. Output light from an optical fiber held in the first ferrule is bent and collimated by a reflective surface, transmitted to the facing reflective surface in a second ferrule aligned by the sleeve, which bends the light to input to the optical fiber held in the second ferrule. The ferrule components and/or sleeve are precision formed by high throughput metal stamping. The ferrule is incorporated in an optical fiber connector.
