1. An apparatus for fabricating an optical fiber cable for use in communication applications, said apparatus comprising:

  • means for forming an assembly having at least one optical fiber encapsulated in a metallic tube having an ultra-small diameter, said assembly forming means comprising means for forming said tube from a strip of metal or metal alloy in a desired condition;

    said tube being characterized by a longitudinally extending seam;

    means for sealing said seam to provide a hermetic tubular structure; and

    means for applying a tensile force to said metal or metal alloy strip to pull said metal or metal alloy strip through said tube forming means, said tensile force applying means being positioned between said tube forming means and said sealing means so as to apply said tensile force to said metal or metal alloy before deration of the condition of said metal or metal alloy.
