Abstract

Connector tips for paired fiber optic strands are protected from damage by a tip protector held in position with one or more flexible members that are disposed to cover the connector tips with the tip protector in an unflexed position and to flex to expose the connector tips by moving the tip protector. The flexible members, such as a pair of extension springs, are coupled to the paired fiber optic strands with a clamp that holds the flexible members on opposing sides of and parallel with the fiber optic strands to provide structural support to the fiber optic strands. Bending of the flexible members from parallel alignment with the fiber optic strands removes the connector tips from a recess of the tip protector. The flexible members are biased to return to the parallel alignment so that the tip protector is biased to return to a position that covers the connector tips.

Claims

1. A system for protecting a fiber optic cable connector tip from damage, the system comprising:

a clamp operable to couple to the fiber optic cable at an adjustable distance from the connector tip;

an extension spring having first and second ends, the extension spring coupled to the clamp at the first end and aligned substantially parallel with the fiber optic cable to have the second end proximate to the connector tip; and

a tip protector having a tip recess shaped to accept the fiber optic cable connector tip, the tip protector coupled to the extension spring second end and operable to cover the fiber optic cable connector tip in an unflexed position and to expose the fiber optic cable connector tip in a flexed position.

2. The system of claim 1 wherein the clamp comprises:

first and second clamp members, each clamp member having a cable recess shaped to accept the fiber optic cable and a spring recess shaped to accept the extension spring; and

an attachment device operable to couple together the first and second clamp members with the cable recesses and the spring recesses of each member aligned so that insertion of the fiber optic cable in the cable recesses and the extension spring in the spring recesses couples the extension spring substantially parallel to the fiber optic cable.

3. The system of claim 2 further comprising plural cable recesses in each clamp member to couple with plural fiber optic cables.

4. The system of claim 2 further comprising first and second spring recesses in each clamp member to couple with first and second extension springs, the springs disposed on opposing sides of the cable recesses to aid in support of the cable.

5. The system of claim 2 wherein the spring recesses and clamp recesses have like dimensions to allow interchangeable use of each recess with a fiber optic cable or extension spring.

6. The system of claim 1 wherein the tip recess comprises an opening along one side of the tip protector that allows flexing of the extension spring along a single path to cover or uncover the fiber optic cable connector tip.

7. The system of claim 1 wherein the tip recess comprises an opening through the tip protector that allows flexing of the extension spring along plural paths to cover or uncover the fiber optic cable connector tip.

8. The system of claim 1 wherein the tip protector comprises polycarbonate.

9. The system of claim 1 wherein the clamp comprises polycarbonate.

12. The method of claim 1 further comprising:

removing the connector tip from the fiber optic connector; and

allowing the flexed spring member to return to the unflexed position to cover the connector tip with the tip protector.

10. A method for protecting fiber optic cable connector tips from damage, the method comprising:

coupling one or more spring members to the fiber optic cable;

coupling a tip protector to the spring members;

aligning the spring members with fiber optic cable to cover the connector tip with the tip protector with the spring members in an unflexed position; and

exposing the connector tip by flexing the spring members.

11. The method of claim 10 further comprising inserting the exposed connector tip into a fiber optic connector.

13. The method of claim 10 wherein the fiber optic cable comprises paired optic strands and aligning the spring members further comprises disposing the paired optic strands between first and second spring members.

14. The method of claim 13 wherein the spring members comprise extension springs.

15. The method of claim 10 wherein exposing the connector tip further comprises bending the spring members to remove the connector tip from the tip protector.

16. A system for protecting paired fiber optic strands, the system comprising:

paired fiber optic strands aligned in a parallel configuration and terminating at an end;

a connector tip coupled to the terminating end of the paired fiber optic strands;

a clamp secured to the paired fiber optic strands distal from the connector tip;

a tip protector disposed proximate the connector tip and operable to protect the connector tip from damage; and

a pair of flexible members extending from the clamp to the tip protector, the flexible members disposed in an unflexed position to run parallel with and on opposing sides of the paired fiber optic strands, the flexible members operable to flex to remove the tip protector from the connector tip.

17. The system of claim 16 wherein the flexible members comprise extension springs.

18. The system of claim 16 wherein the clamp comprises:

first and second opposing clamp members, each clamp member having first and second cable recesses disposed to accept the paired optic strands and first and second flexible member recesses disposed to accept the flexible members; and

an attachment device operable to secure the first and second clamp members to each other with the paired optic strands in the cable recesses and the flexible members in the flexible member recesses.

19. The system of claim 18 wherein the first and second opposing clamp members comprise polycarbonate.

20. The system of claim 16 wherein the tip protector comprises polycarbonate formed with a recess aligned so that flexing of the flexible member pair from parallel alignment with the paired optic strands to nonparallel alignment removes the connector tip from the recess.
