METHOD OF COATING OPTICAL WAVEGUIDE FILAMENTS AND COATING DIE

摘要

A method of coating an optical waveguide filament employing a die body having an at least partly tapered central aperture and radial means for introducing coating material to the central aperture is disclosed. The method includes exposing the optical waveguide filament to the coating material within the tapered aperture of the die body. The die body and an apparatus for coating the filament is also disclosed.
