ABSTRACT:
A method and apparatus for cutting an optical fiber along a plane that is either oblique or perpendicular to its axis. In principle, a predetermined portion of a fiber is held between a fixed holding fixture and a driven retaining fixture. The driven fixture is adapted to travel in an orbiting, spiraling path. A cutting device is mounted adjacent to the fiber portion and between the fixed and driven fixtures. Upon activation, the driven fixture orbits in a spiraling path and successively, the fiber will contact the cutting edge of the cutting device when the radius of the traveled orbit is equal to the radius of the cutting edge. This contact with the cutting edge causes the fiber to be scribed circumferentially in a plane either oblique or perpendicular to its axis depending on the mounting angle of the cutting device. Further spiraling of the driven fixture bends the fiber at the scribe and causes the fiber to snap or break in the plane of the scribe mark.
