Abstract

An optical fiber feedthrough comprising a glass seal for sealing the optical fiber within a metal sleeve. The fiber is held in a fixed position with respect to the sleeve while a glass solder, preferably an annular preform, is heated to its glass transition temperature and then cooled to form a glass to metal seal.
