A clip to align a fiber optic cable with a light source within a fiber module. The clip may have a pair of sidewalls that are separated by a channel. The fiber optic cable can be located within the channel of the clip and attached to the sidewalls. The sidewall are adjoined by a pair of joining segments. The joining segments are separated by a space which allows a ferrule of the fiber optic cable to be welded to a center location of the clip.

Apparatus and process for welding a fiber optic cable

Clip that aligns a fiber optic cable with a laser diode within a fiber optic module

A process for laser welding a ferrule of a fiber optic cable to a clip of a fiber module. The process can detect and correct a movement of the fiber optic cable so that the fiber is aligned with a light source such as a laser diode. The detection method includes the steps of mechanically moving the ferrule with an automated device after a weld is completed and then detecting a change in optical power of a light beam that is transmitted through the fiber optic cable. The detection can determine a direction that the ferrule shifted during the weld process. The shift of the ferrule can be corrected by subsequent laser welds of the ferrule and clip. The power and time duration of the laser welds can be determined from an empirically derived look-up table. The entire process of detection and correction can be automated.
