ABSTRACT:
A device for coating an optical fiber, for example a glass fiber drawn from a glass preform, comprises a housing (3) with a lengthwise bore (11), into which a nozzle holder (13) containing a receiving aperture (25) is press-fit. An inlet nozzle (33) and an outlet nozzle (43), through which the optical fiber (1) can pass, are press-fit into the receiving hole (25) of nozzle holder (13) at a distance from each other. A coating space for applying a coating material to the optical fiber (1) is located between the inlet nozzle (33) and the outlet nozzle (43). The press-fitting of the nozzles (33, 43) into the nozzle holder (13), and press-fitting the nozzle holder (13) into the housing, achieves better reproducibility of the nozzle (33, 43) positioning when the device is being assembled.
