ABSTRACT:
A flexible hollow glass tube of optical fiber dimensions provides a central light passage and serves as an optical transmission line characterized by substantially less absorption and distortion of signals superposed on transmitted light waves. A metal rod located within a preform evaporates as the preform is heated and drawn, providing a convenient method of reflectively coating the internal surface of small tubes.
