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.
