  • Method for coating an optical fiber
    Patent number: 6044665
    Abstract: A method for coating an optical fiber (1) has the optical fiber (1) exiting the longitudinal direction through a coating nozzle (10) from a volume (11) which is filled with a liquid hardenable coating material (6). The surface of the fiber is spaced from the wall (12) of the coating nozzle (10). The viscosity of the coating material (6) at room temperature is greater than 2500 mPa.multidot.s and the temperature of the coating material (6) is adjusted high enough for the coating material (6) to have a viscosity of less than 2000 mPa.multidot.s.

  • Method of drawing an optical fiber
    Patent number: 5897681
    Abstract: To draw an optical fiber (10) from one end of a glass preform (9) which is heated to above the glass softening temperature at least in that area, a gas (21) flows around the preform (9) into a furnace space (16) during the drawing process and subsequent feeding of the preform. During the feeding, the areas that are adjacent to the drawing end of the preform (9) pass through gas zones in which the helium content of the furnace gas increases in the drawing direction.
