Abstract: A device includes a stub, and an optical fiber. The stub has an aperture, and a first end and a second end. The optical fiber is mounted in the aperture of the stub. The optical fiber has a first end and a second end. The first end of the optical fiber is polished so as to be flush with the first end of the stub. The second end of the optical fiber is cleaved at a predetermined position so as to provide for a predetermined length of the optical fiber measured from the first end of the optical fiber to the second end of the optical fiber.

Abstract: A multi-fiber optic device includes two optical fibers and a body. The body is formed around and adhered to the two optical fibers. The body includes two alignment bosses, a mating end and a tapered end. Each alignment boss includes an alignment aperture.

Abstract: A device includes two optical fibers bonded to a body. The body has a mating end and a splicing end. Each of two optical fibers has a respective polished end and splicing end. The polished end of two optical fibers is situated adjacent to and flush with the mating end of the body. The length of the two optical fibers is the same, where the length is defined by the distance from the splicing end to the polished end. The length of the two optical fibers is greater than the length of the body as defined by the distance from the mating end to the splicing end of the body. The length of the two optical fibers is less than fifty millimeters. The two optical fibers are parallel to one another.

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.

Abstract: An optical fibre connector which can be connected or disconnected underwater without contamination of optical fibre termination lenses. When the connector is disconnected, the terminations of each connector element are disposed in respective chambers which are sealed by respective diaphragms. Upon connection the two diaphragms are brought into sealing contact and the terminations of one connector element caused to enter the chamber of the other connector element following penetration of both diaphragms.
