Abstract
A UVLED apparatus and method provide efficient curing of an optical-fiber coating onto a drawn glass fiber. The apparatus and method employ one or more UVLEDs that emit electromagnetic radiation into a curing space. An incompletely cured optical-fiber coating, which is formed upon a glass fiber, absorbs emitted and reflected electromagnetic radiation to effect improved curing.
Claims19
A method for curing a coating on a glass fiber, comprising:
- emitting UV radiation from one or more sources of electromagnetic radiation toward a curing space;
- focusing with a lens at least some of the emitted UV radiation toward a curing axis within the curing space, the lens having a focal point at the curing axis;
- transmitting a portion of the lens-focused UV radiation to the curing axis;
- and
- passing through the curing space and along the curing axis a glass fiber having an incompletely cured coating to effect the absorption of the lens-focused UV radiation.

A method for curing a coating on a glass fiber, comprising:
- passing through a curing space a glass fiber having an incompletely cured coating;
- emitting toward the curing space UV radiation from one or more sources of electromagnetic radiation;
- and
- focusing with a lens at least some of the emitted UV radiation toward the glass fiber having an incompletely cured coating such that the coated glass fiber passes through the focus of the lens to absorb at least some of the emitted UV radiation.
