Abstract
An optical fiber coupling element in which a short length of optical fiber is placed in a glass sleeve with one end of the fiber projecting from the sleeve. The glass sleeve is collapsed onto the fiber, and a watch jewel is fitted over the fiber end. The other end of the sleeve is flared to facilitate the insertion into it of a second fiber. The sleeve and jewel are sealed into one end of a ferrule.
