Abstract
A hermetically sealed fiber optic feedthrough module which comprises a metal or other rigid material connector feedthrough or sleeve feedthrough with a single fiber optic member or with a multitude of optical fibers extending through and protruding out of either side of the connector feedthrough or sleeve feedthrough and a pressure-blocking sealant material of polycrystalline which surrounds the fiber optic member(s) and provides a seal between the fiber optic member(s) and the inside surface of the connector or sleeve feedthrough. The feedthrough module is made by positioning the fiber optic member(s) through the connector or sleeve feedthrough and applying the polycrystalline sealant material between the fiber optic member(s) and the connector or sleeve feedthrough inside diameter to fill all voids between the fiber optic member(s) and connector or sleeve feedthrough. Heat is then applied to 'set' the polycrystalline or other material which provides hermetically sealed intimate contact between the various feedthrough module components.
