ABSTRACT:
A system for machining and sizing optical fibers is described herein. The system uses a laser beam to machine oversized regions of a buffer material surrounding an optical fiber to create a coated optical fiber having a substantially uniform maximum outer dimension that is within a desired tolerance specification. The machining of the buffer material to size the optical fiber is accomplished by generating at least one laser beam transverse to the buffer material, rotating the beam or beams about an axis coaxial with the optical axis of the optical fiber, and moving the fiber past the rotating laser beam or beams. The rotating laser beam or beams vaporize any excess or oversized regions of buffer material and substantially provide the optical fiber with the desired outer dimension or diameter.
