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.
Claims9
A method for the production of one-material optical fibers having at least one light conducting core component supported by a support component in a surrounding protective casing, said method comprising the steps of forming a one-piece blank having at least one light conducting core component integrally formed with a thin supporting component that extends between a pair of casing components whose side edges are spaced apart to provide an open cross section for the blank, working the blank to force the side edges of at least one of the casing components into engagement with the side edges of the other casing component to close the cross section and to form a blank with a closed 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 said one-material optical fiber.
