Connection between two light conducting glass fibers

Claim 1

A connecting means for glass fibers comprising, a first core glass fiber, a second core glass fiber, coating glass surrounding each core glass fiber and forming a sheath therefor, a conical glass component part for each glass fiber having a recess in the small diameter end of said conical glass component part for receiving the core glass fiber and coating glass to extend generally along the axis of said conical glass component part, each conical glass component part having a refractive index profile in which the periphery of the recess radially to the outer surface of the conical glass component part has the same refractive index as the coating glass forming a sheath for the core glass fiber, and the region of the conical glass component part extending from the inner end of the recess to the large diameter end of the conical glass component part has the same refractive index extending in an axial direction as the core glass fiber, and slopes constantly down in all directions toward the conical sheathing surface of the conical glass component part, a mass of machinable material surrounding each conical glass component part, and a centering ring surrounding the mass and retaining the conical glass components parts in end-to-end relation with respect to each other.
