Abstract

The invention includes an optical waveguide whipping end cutting apparatus. The apparatus includes an active cutting element. The element is positioned to cut a segment from a whipping end of an optical fiber, while the fiber is being wound onto a rotating spool. This apparatus will prevent fiber whip. The invention also includes a method of cutting a whipping end from an optical fiber. The method includes removing a segment of the end of the fiber with an active cutting element. A method of cutting an optical fiber while winding the fiber onto a storage spool is further discussed. The fiber has a whipping end and a wound segment. The method includes separating the whipping end of the fiber from the wound segment with an active cutting element. Furthermore, the invention includes a method of reducing fiber whip damage to fiber wound on a spool. This includes engaging an active cutting element on the fiber being wound onto the spool, and removing a whipping end from the fiber.

Claims

1. An optical fiber cutting apparatus comprising an active cutting element which is positioned to cut a segment from an end of an optical fiber, while the fiber is wound onto a rotating spool, and thereby prevent fiber whip.

2. The apparatus of claim 1 wherein said element includes a rotatable hub having a plurality of cutting arms extending from said hub.

3. The apparatus of claim 2 further comprising a surface to retain the fiber for engagement by said arms.

4. The apparatus of claim 1 wherein said element includes a first cutting surface which is adjacent to and oscillates with respect to a second cutting surface.

5. The apparatus of claim 4 wherein the second cutting surface is stationary.

6. The apparatus of claim 1 further comprising a surface positioned to guide said fiber after said cutting element cuts said segment from said fiber.

7. The apparatus of claim 6 wherein said surface is a fiber guide.

8. The apparatus of claim 7 wherein said fiber guide is circular.

9. The apparatus of claim 7 wherein said fiber guide is noncircular.

10. The apparatus of claim 1 further comprising a channel to direct said segment toward said element.

11. The apparatus of claim 1 wherein said segment is a whipping end.

12. A method of cutting a whipping end from an optical fiber, said method comprising removing a segment of the end of the fiber with an active cutting element and, prior to said removing, winding the fiber on a spool, said cutting element is positioned to cut said fiber and thereby prevent whip damage to the fiber wound on the spool.

13. The method of claim 12 wherein said removing includes a cutting surface of the element moving into a surface of the fiber.

14. The method of claim 12 wherein the fiber is in contact with a guide surface after said removing.

15. A method of cutting an optical fiber while winding the fiber onto a storage spool, the fiber having a whipping end and a wound segment, said method comprising:

separating the whipping end of the fiber from the wound segment with an active cutting element.

16. The method of claim 15 wherein said separating is accomplished by engaging a cutting surface of the element with the fiber.

17. An optical fiber cutting apparatus comprising:

an optical fiber, having an end, being wound onto a rotating spool; and

an active cutting element positioned nearby the spool to cut a segment from said end to thereby prevent fiber whip.

18. A method of cutting a whipping end from an optical fiber, said method comprising:

removing a segment of the whipping end of the fiber with an active cutting element and,

prior to said removing, winding the fiber on a spool.
