Abstract
An optical fiber connector in which each fiber is terminated by a coupling element comprising a cylindrical transparent body having a concave reflector on one end facing into the body and a circular reflector on the opposite end facing the concave reflector. The circular reflector has a diameter less than that of the cylindrical body and is concentric therewith. This arrangement has the advantage that the main focussing elements are reflectors and therefore require far less curvature than lenses.
