ABSTRACT:
A method for producing one-material optical fibers having at least one light conducting component supported in a protective sleeve or casing characterized by forming a one-piece blank having an open cross section by either pressing, continuous casting, chill casting or rolling, working the blank to close the cross section, heating the blank with the closed cross section to a suitable temperature for drawing and drawing the blank with the closed cross section into the one-material optical fiber having a closed cross section. Preferably, the protective casing during the step of forming is formed in two casing components having edges extending along the length of the blank and spaced apart and the step of working the blank forces the edges into engagement with each other to form a closed cross section.
