Abstract: A connector for mounting to and through a wall of a device. In one form of the invention a connector is used for mounting to and through a wall of a device. The connector includes a body, an optical fiber, and a sealant. The body includes a surface having an aperture. The optical fiber has a length and a first end and a second end. A portion of the length of the optical fiber being metallized. The optical fiber passes through the aperture of the surface of the body and the metallized portion of the optical fiber is attached to the aperture of the surface of the body so as to form a hermetic seal between the optical fiber and the aperture of the surface of the body. The sealant is located between the body and the surface of the device so as to provide a hermetic seal between the body and the wall of the device when the body is urged toward the wall of the device thus deforming the sealant. The connector allows an optical signal to be transmitted within the optical fiber through the body.
