Abstract
A tool for chamfering cleaved tips of optical fibers. The tool including conical bores of relatively smooth and hard material terminate at a cylindrical bore that is slightly larger than the fiber core maximum diameter and a fiber centering bore that is slightly larger than the fiber coating maximum diameter. The tool provided such that when a cleaved fiber tip is inserted into the centering bore the sharp edge falls upon the chamfering surface that, when rotated relative to the fiber, gently grinds the edge to the chamfer angle. Chamfering cannot occur on the core face due to the absence of tool surface at this dimension.
Claims13
A tool comprising:
- a die with a bore within the die, the bore having a first axis and
- a first cylindrical portion with a first diameter,
- a second cylindrical portion having a second diameter that is smaller than the first diameter, and
- a first conical portion including a first base that has the first diameter and a second base that has the second diameter, said first conical portion connecting the first and second cylindrical portions, and
- a housing body shaped as a bar having distal and proximal ends, a second axis, and an axial recess dimensioned to fixate at least a portion of the die therein when the first and second axes substantially coincide,
- wherein a surface of the first conical portion possesses at least one of
- (1a) a first hardness that is greater than a second hardness of a glass material, and
- (1b) a first averaged surface roughness that is greater than a second averaged surface roughness of a surface of any of the first and second cylindrical surfaces, and
- wherein the tool is configured to chamfer an optical fiber.
