Patent ID: 7013073

Claim:
A method for fixing a fiber at the center of a ferrule, comprising: (a) mounting the ferrule on a heating stage; (b) mounting the fiber on a first moving stage and adjusting the position of the first moving stage so that one end of the fiber is disposed near an inlet of the ferrule; (c) heating the ferrule to a proper working temperature; (d) monitoring the position of the fiber in the ferrule by utilizing at least one charge-coupled devices (CCD), wherein the charge-coupled device is connected to a processor unit so as to measure the eccentric offset of the fiber in the ferrule; (e) adjusting the first moving stage so that the fiber is concentric with the ferrule, and then inserting the fiber into the ferrule and through-out the outlet of the ferrule; (f) sealing the ferrule with a solder material; and (g) solidifying the solder material to obtain a fiber-solder-ferrule.
