ABSTRACT:
An optical fiber connector comprises a first fiber one end of which is in abutment with one end of a second optical fiber, the first and second fibers having substantially the same outside diameter and the second fiber having the same core diameter but a higher numerical aperture than the first. A mirror is arranged to focus light transmitted between the end of the second fiber and an optical transducer. The mirror defines an opening through which the first fiber extends.
