Abstract

PURPOSE:To improve low temperature resistance and heat resistance of optical fibers and prevent them from troubles such as the increment of diameter and nonflexibility without the incorporation of a water cooling material by coating them with aromatic polyimide or aromatic polyamide-imide synthetic resin. CONSTITUTION:Immediately after rolling the base material 1 of an optical fiber while heating it with heaters 2, a optical fiber 1' is coated with aromatic polyimide or aromatic polyamide-imide synthetic resin by a coating die 3. The synthetic resin covering the optical fiber is baked by a baking furnace 5 to form a protecting layer and then wound up by a winder 6. The thickness of the protecting layer is regulated to about 20mu. Thus obtained flexible optical fiber with an appropriate diameter can be used in the wide temperature range of about -269-+400 deg.C and resists frames up to about 800 deg.C. The optical fiber has also superior chemical resistance and radiation resistance.
