Abstract

An optical fiber connector for a fiber optic ribbon cable includes a guide boot and a termination plug. The guide boot comprises an outer sleeve or body that defines an inner passageway, and a first end for receiving the cable and a termination port. The body has an inner passageway for guiding, bending, and/or twisting the cable and is angled at a desired angle. The inner passageway is preferably tapered or otherwise spiraled to control the location and amount of circumferential rotation (twisting) of the cable. Alternately, the cable can be inserted into and through the guide boot without any twisting, and then twisted or otherwise rotated when the guide boot is connected with the termination plug. Locking tabs are preferably provided in an end of the termination plug to engage the termination port, thereby holding the guide boot in connection with the termination plug.

Claims

1. A two-piece boot assembly for use with a fiber optic cable, said boot assembly comprising:

a guide boot comprising;

a first end for receiving the fiber optic cable;

a termination port at an end opposite the first end, from which the fiber optic cable extends, and

a body disposed between the first end and the termination port and defining an inner passageway for the fiber optic cable; and

a termination plug having a first end for receiving the fiber optic cable and a second end, the termination plug restraining the fiber optic cable from twisting and rotating in relation thereto.

2. The connector of claim 1, wherein the termination plug is adapted to be detachable connectable to the termination port of the guide boot.

3. The connector of claim 1, wherein the body is angled at a predetermined angle.

4. The connector of claim 3, wherein the predetermined angle is one of about 45 degrees and about 90 degrees.

5. The connector of claim 1, wherein the body has an outer diameter that decreases toward the first end.

6. The connector of claim 1, wherein the first end of the guide boot is oval-shaped.

7. The connector of claim 1, wherein the termination port has a round opening and an octagonal-shaped exterior.

8. The connector of claim 1, wherein the inner passageway is circular.

9. The connector of claim 1, wherein the termination plug further comprises locking tabs for locking the first end of the termination plug with the termination port.

10. The connector of claim 1, wherein the guide boot comprises a first cut-out window disposed on the body towards the first end and a second cut-out window disposed on the body towards the termination port.

11. The connector of claim 10, wherein the first cut-out window is disposed on an opposite side of the body from the second cut-out window.

12. The two-piece boot assembly of claim 1, wherein the first end of the guide boot receives a first portion of the fiber optic cable and restrains the first portion of the fiber optic cable from rotating and twisting in relation thereto, the first end of the termination plug receives a second portion of the fiber optic cable, and rotation of the guide boot to a first orientation in relation to the termination plug causes the first portion of the fiber optic cable to rotate and twist in relation to the second portion of the fiber optic cable.

13. The two-piece boot assembly of claim 12, wherein the guide boot mates with the termination plug when the guide boot is rotated to the first orientation in relation to the termination plug.

14. The two-piece boot assembly of claim 13, wherein the guide boot and the termination plug have complemeptary shapes that prevent the guide boot from rotating in relation to the termination plug when the guide boot is mated with the termination plug.

15. A fiber optic cable assembly, comprising:

a connector;

a fiber optic cable terminating at said connector; and

a boot assembly for controlling said cable upon exiting from said connector, said boot assembly comprising;

a termination plug adjacent said connector for receiving the fiber optic cable and restraining the fiber optic cable from twisting and rotating in relation thereto; and

a guide boot mateable with said termination plug, said guide boot including;

a first end opposite said termination plug for receiving said fiber optic cable;

a termination portion adjacent said termination plug and from which said cable extends; and

a body disposed between said first end and said termination portion and defining an inner passageway for said cable.

16. The fiber optic cable guide boot of claim 15, wherein the body is angled at a predetermined angle.

17. The fiber optic cable guide boot of claim 16, wherein the predetermined angle is one of about 45 degrees and about 90 degrees.

18. The fiber optic cable guide boot of claim 15, wherein the body has an outer diameter that decreases toward the first end.

19. The fiber optic cable guide boot of claim 15, wherein the guide boot comprises a first cut-out window disposed on the body towards the first end and a second cut-out window disposed on the body towards the termination port.

20. The fiber optic cable guide boot of claim 19, wherein the first cut-out window is disposed on an opposite side of the body from the second cut-out window.

21. The fiber optic cable assembly of claim 15, wherein the first end of the guide boot receives a first portion of the fiber optic cable and restrains the first portion of the fiber optic cable from rotating and twisting in relation thereto, the termination plug receives a second portion of the fiber optic cable, and rotation of the guide boot to a first orientation in relation to the termination plug causes the first portion of the fiber optic cable to rotate and twist in relation to the second portion of the fiber optic cable.

22. The fiber optic cable assembly of claim 21, wherein the guide boot mates with the termination plug when the guide boot is rotated to the first orientation in relation to the termination plug.

23. The fiber optic cable assembly of claim 22, wherein the guide boot and the termination plug have complementary shapes that prevent the guide boot from rotating in relation to the termination plug when the guide boot is mated with the termination plug.

24. A method of inserting a fiber optic cable into a connector comprising a guide boot having a first end and a termination port, and a termination plug having a first end and a second end, comprising:

inserting the fiber optic cable into the first end of the guide boot, through an inner passageway of the guide boot, and out the termination port;

inserting the end of the fiber optic cable received from the termination port into the first end of the termination plug;

rotating said guide boot in relation to the termination plug so that the end of the fiber optic cable rotates and twists in relation to a portion of the fiber optic cable positioned within the guide boot; and

engaging the guide boot and the termination plug.
