International ClassC03B 023/20AbstractThe invention is a method of making fiber optic-to-metal connection seals. The optical fiber and a preform made of a sealing material are inserted into a metal cup. The metal is then heated to a temperature which melts the sealing material to form a hermetic seal between the cup and the fiber optic. The hermetic sealing material is selected from glass, glass-ceramic or braze and the metal is selected form stainless steel, a metal alloy or a high-strength superalloy. In a preferred method, the optical fiber is coated with a plastic buffer or pliant metal jacket.Field of SearchFree metal or metal alloy containing coatingProcess of manufacturing optical fibers, waveguides, or preforms thereof With fusion bonding glass to a formed part (e.g., devitrified seals, glass to metal, etc.) With coating By or with coating at joint interface of a formed part prior to bonding Forming lens integral with optical fiber Joining or bonding optical fibers, waveguides, or preforms (e.g., coupling, etc.) Diverse Of glass product Glass applied in powdered (i.e., frit) form | |
