Abstract

A fiber optic cable guide has a curved elongated member that fits between the strain relief boot and optical fiber to allow the fiber optical cable to bend without violating the minimum bend radius of the optical fibers. The fiber optic cable guide also retains at least a portion of the fiber optic cable.

Claims

1. A fiber optic cable guide for removable placement on a fiber optic cable, the fiber optic cable having a minimum bend radius, a connector at at least one end, and a strain relief boot having a first end adjacent the connector, the fiber optic cable guide comprising:

an elongated member partially curved along its length with a radius of curvature not less than the minimum bend radius of the fiber optic cable, the elongated member having a first end and a second end, the first end of the elongated member dimensioned to fit between the fiber optic cable and strain relief boot at an end opposite the first end of the strain relief boot and the second end of the elongated member configured to retain at least a portion of the fiber optic cable.

2. The fiber optic cable guide of claim 1, wherein the second end includes at least one extension configured to wrap around at least a portion of the fiber optic cable.

3. The fiber optic cable guide of claim 1, wherein the first end has a hook portion to engage a portion of the strain relief boot.

4. The fiber optic cable guide of claim 1, wherein the guide is curved through about 90 degrees.

5. The fiber optic cable guide of claim 2, wherein the second end has at least two extensions configured to wrap around at least a portion of the fiber optic cable.

6. The fiber optic cable guide of claim 5, wherein the two extensions extend from opposite sides of the elongated member and are wrapped in opposite directions to generally conform to and loosely hold the optical fiber cable.

7. The fiber optic cable guide of claim 2, wherein the at least one extension allows axial movement of the fiber optic cable within the extension.

8. The fiber optic cable guide of claim 2, wherein the at least one extension can be crimped around the fiber optic cable to securely hold the cable.

9. The fiber optic cable guide of claim 4, wherein the at least two extensions are disposed at two different axial positions along the second end of the fiber optic cable guide.

10. The fiber optic cable guide of claim 1, the elongated member has a shoulder on each side between the first and second ends, the shoulder limiting insertion of the first end between the boot and fiber optic cable.

11. The fiber optic cable guide of claim 1, wherein the fiber optic cable is a fiber optic ribbon cable.

12. The fiber optic cable guide of claim 1, wherein the fiber optic cable is a round fiber optic cable.

13. The fiber optic cable guide of claim 1, wherein the guide is configured to be disposed on an underside of the fiber optic cable.

14. The fiber optic cable guide of claim 1, wherein the guide has a thickness, the thickness defining a plane, and the curvature of the guide being in the thickness plane.

15. The fiber optic cable guide of claim 1, wherein the guide has a width, the width defining a plane and the curvature of the guide being in the width plane.

16. The fiber optic cable guide of claim 1, wherein the guide has a width and a thickness, the width and thickness each defining a plane, the guide being curved in the planes of both the width and the thickness.

17. A method of removably routing a fiber optic cable through a curve, the fiber optic cable having a minimum bend radius, a connector at at least one end, and a strain relief boot adjacent the connector, the method comprising the steps of:

inserting a first end of an elongated optical cable guide member between the fiber optic cable and strain relief boot, the cable guide being partially curved along its length with a radius of curvature not less than the minimum bend radius of the fiber optic cable;

sliding the optical cable guide toward the connector; and

positioning the fiber optic cable into at least one extension configured to hold at least a portion of the fiber optic cable at a second end of the cable guide.

18. The method of claim 17, wherein the fiber optic cable has a connector at both each end, the method allows the removable placement of the cable guide on the fiber without disturbing the connectors.

19. The method of claim 17, further comprising the step of wrapping the at least one extension to hold the fiber optic cable against the elongated member.

20. A fiber optic cable guide for removable placement on a fiber optic cable, the fiber optic cable having a minimum bend radius, a connector at least one end, and a strain relief boot having a first end adjacent the connector, the fiber optic cable guide comprising:

an elongated member partially curved along its length with a radius of curvature not less than the minimum bend radius of the fiber optic cable, at least a portion of the elongated member configured to pass between the strain relief boot and the cable at an end opposite the first end of the strain relief boot.

21. The fiber optic cable guide of claim 20, wherein the elongated member is further configured to retain at least a portion of the fiber optic cable extending beyond the strain relief boot.

22. The fiber optic cable guide of claim 20, wherein the guide is configured to be disposed on an underside of the fiber optic cable.

23. The fiber optic cable guide of claim 20, wherein the guide has a thickness, the thickness defining a plane, and the curvature of the guide being in the thickness plane.

24. The fiber optic cable guide of claim 20, wherein the guide has a width, the width defining a plane and the curvature of the guide being in the width plane.

25. The fiber optic cable guide of claim 20, wherein the guide has a width and a thickness, the width and thickness each defining a plane, the guide being curved in the planes of both the width and the thickness.
