ABSTRACT:
An optical fiber termination connector includes an elongated structure with chamber extending therethrough open at both ends, a fiber disposed in the chamber and spaced therefrom, a solid first material disposed in the chamber around the fiber, and an air gap in the chamber around the end of the fiber. The process includes the steps of locating a fiber in a chamber disposed vertically, with the end of the fiber extending beyond the lower portion of chamber; dipping a lower portion of the chamber into a first material in liquid form so that the first material enters the lower portion of the chamber to a level below an exit port located in the lower portion of the chamber; solidifying the first material disposed in and around the chamber and the fiber; above the solid first material; polishing the lower end of the fiber until it is flush with the chamber at the lower thereof; and removing the first material to form an air gap between the fiber and the lower portion of the chamber. The air gap is large enough to allow independent thermal expansion of the fiber.
