Abstract

This article describes an apparatus for automatically and uniformly polishing the fiber ends in assembled fiber-optic connectors. The apparatus includes a rotating drum assembly with several axially-spaced drums wrapped with abrasive sheet materials. Successive drums have successively finer grit. The fiber-optic connector is moved axially along the drum assembly with its end in contact with the drum surfaces. Referring to Fig. 1, the rotating drum assembly has three successive drums 10, 12, and 14 mounted on a common shaft 16, which is rotated by drum drive motor 18. The shaft 16 is journaled in a base 20 which contains a sanding fluid reservoir 22. The base 20 supports a guide bar 24 and a worm gear 26. An assembled fiber-optic connector can be mounted on a shuttle 28 at an attachment port 30.

Axial Polishing Drum for Fiber Optic Connectors

This article describes an apparatus for automatically and uniformly polishing the fiber ends in assembled fiber-optic connectors. The apparatus includes a rotating drum assembly with several axially-spaced drums wrapped with abrasive sheet materials. Successive drums have successively finer grit. The fiber-optic connector is moved axially along the drum assembly with its end in contact with the drum surfaces. Referring to Fig. 1, the rotating drum assembly has three successive drums 10, 12, and 14 mounted on a common shaft 16, which is rotated by drum drive motor 18. The shaft 16 is journaled in a base 20 which contains a sanding fluid reservoir 22. The base 20 supports a guide bar 24 and a worm gear 26. An assembled fiber-optic connector can be mounted on a shuttle 28 at an attachment port 30. When the worm gear 26 is rotated by an axial drive motor 32, the shuttle is driven along a path generally parallel to the axis of the shaft 16. Each of the drums is wrapped with a strip of sand paper, the ends of which are secured by conventional mechanisms in slots, such as slots 32A and 32B in cylinder 10. Each of the cylinders also includes a scan bar, such as scan bar 34 on cylinder 10. The scan bar is a reflective surface. When light is injected into the optical fiber being polished by a source located at one arm of a Y connection, the light is reflected from the scan bar back through the fiber to a detector located at t...
