ABSTRACT:
The present invention relates to a method of attaching an optical fiber alignment ferrule to a connector body, the first end of which is lens-shaped. The body has an indented region in the second end thereof opposite the lens, the indented region being centered on the optical axis of the lens. The body is mounted in a cavity in an alignment fixture which also includes a bore that is aligned with the cavity. The bore is so positioned that when a connector body is mounted in the cavity, the axis of the bore is coaxial with the optical axis of the lens. A rigid alignment rod is slidably mounted in the bore so that the rod is capable of only longitudinal movement along its axis. One end of the rod is inserted through the hole in a tubular ferrule. The rod is advanced toward the connector body until the rod contacts the bottom of the indented region. The ferrule is moved along the rod until it contacts the second surface of the body. The ferrule is then bonded to the body.
