Abstract
Fibers, including optical fibers, are coated under pressure to reduce the amount of bubbles entrapped in the coating. Fluid coating material is directed radially toward the fiber, typically through a porous material or radial channels in a coating applicator. The passage diameter for the fiber is large enough to prevent contacting the fiber, while the pressure of the fluid coating material is high enough to substantially prevent air from entering the applicator. Fiber coating speeds up to at least several meters/second are possible.
