Fiber optic feed-through tube and method for making the same

摘要

A fiber optic feed-through tube, a method for making it and a method for hermetically sealing and aligning lightwave waveguides inserted into the tube. The feed-through tube is preferably a metal tube with low melting point hermetic sealing material deposited on one end and the lightwave waveguide is an optical glass fiber. The fiber is fed through a tube having low melting point hermetic sealing material on one end.
