Abstract
Polishing machines, fixtures and methods for polishing one or more optical fibers upon distinct wear paths are provided. For example, in some embodiments a polishing fixture is provided with a number of ports for fixing optical fibers. The ports may be positioned within the fixture to follow a number of distinct wear paths when the fixture is moved relative to a platen retaining an abrasive film. In some embodiments, the ports may have an angular separation or be positioned at one or more radial distances in order to provide distinct wear paths on the abrasive film.

An optical fiber polishing fixture for use with an optical fiber polishing machine, the fixture comprising:
- a base having a bottom surface and a plurality of ports;
- wherein the ports are positioned about a center of the base and extend through the bottom surface of the base;
- wherein each port is configured to align an optical fiber above a platen of the optical fiber polishing machine for polishing an end of the optical fiber as the platen and the fixture undergo a relative motion, the relative motion comprising a rotational motion in which the platen rotates about an axis of the platen and a revolving motion in which the platen revolves a first amount of revolution about the center of the base for every rotation of the platen;
- and
- wherein an angular separation between at least a first port and a second port with respect to the center of the fixture base is a sum of a multiple of the first amount of revolution and the first amount of revolution divided by the quantity of the plurality of ports, such that the first port and the second port follow distinct wear paths upon an abrasive surface on the platen as the platen and the fixture undergo the relative motion.
An optical fiber polishing fixture for use with an optical fiber polishing machine, the fixture comprising:
- a base having a bottom surface and a plurality of ports;
- wherein the ports are positioned about a center of the base and extend through the bottom surface of the base;
- wherein each port is configured to align an optical fiber above a platen of the optical fiber polishing machine for polishing an end of the optical fiber as the platen and the fixture undergo a relative motion;
- wherein an angular separation between at least a first port and a second port with respect to the center of the fixture base is based on the relative motion of the platen and the fixture such that the first port and the second port follow distinct wear paths upon an abrasive surface on the platen as the platen and the fixture undergo the relative motion;
- and
- wherein the first port and the second port are positioned from the center of the base at respective radial distances varying by at least about a width of an optical fiber, but by no more than about the width of the optical fiber times the quantity of the plurality of ports, wherein the varying radial distances of the first port and the second port produce distinct wear paths upon the abrasive surface on the platen for the first port and the second port as the platen and the fixture undergo the relative motion.
An optical fiber polishing fixture for use with an optical fiber polishing machine, the fixture comprising:
- a base having a bottom surface and a plurality of ports;
- wherein the ports are positioned about a center of the base and extend through the bottom surface of the base;
- wherein each port is configured to align an optical fiber above a platen of the optical fiber polishing machine for polishing an end of the optical fiber as the platen and the fixture undergo a relative motion;
- wherein at least a first group of the plurality of ports are substantially positioned along a first circular path about the center of the base;
- wherein a first port and a second port in the first group of ports are positioned from the center of the base at respective radial distances varying by at least about a width of an optical fiber, but by no more than about the width of the optical fiber times the quantity of ports in the first group;
- and
- wherein the varying radial distances of the first port and the second port produce distinct wear paths upon an abrasive surface on the platen for the first port and the second port as the platen and the fixture undergo the relative motion.
