Abstract
A connector for connecting an optical fiber to another optical fiber or other optical signal receiving device, the connector having an elongated body with a central bore which is larger than the optical fiber with a protective layer thereon so that the latter freely slides in the bore. The body also has a pair of spaced reference elements or shoulders on its exterior surface, and a bushing with elastic fingers encircles the portion of the body with the shoulders and is longitudinally slidable between positions in which it engages one shoulder or the other shoulder. The bushing also has a ferrule with a bore for the passage of the bare optical fiber. Also, a method for accurately positioning the fiber in the connector, in which the fiber is cut while it extends from the ferrule and the bushing engages the shoulder farther from the cut, and the bushing is then moved so that it engages the other shoulder and is secured to the body.
