Abstract
An assembly including a fiber optic cable assembled with a one-piece ferrule where a gap exists between the fiber optic cable and the ferrule. When the fiber optic cable is mounted to the ferrule, the optical fiber is positioned within a small opening and the sheath is positioned within a large opening of the ferrule. The gap exists between the optical fiber and the small opening. The metallic material is then adhered to a portion of the optical fiber and to a portion of the ferrule so as to form the hermetic seal at the gap. The layer of the metallic material can be deposited by way of a metal vapor deposition process. Another assembly may include multiple fiber optic cables trapped between two substrates where any gaps formed between the two substrates are hermetically sealed with a metallic material.
