Abstract

A pre-terminated end of a fiber optic cable has a protective cap that protects the optical fiber and the ferrule assembly at the terminal end. The protective cap has an attachment feature enabling a pull cord to attach to the protective cap. The protective cap has a body including an exterior surface and a receptacle formed in the body and configured to receive a portion of the fiber optic cable, and the attachment feature. The attachment feature includes a cavity formed in a tip of the body and at least two openings formed in the exterior surface of the body and connected to the cavity.

First claim

The invention claimed is:

1. A protective cap for a fiber optic cable, comprising
a body of the protective cap including an exterior surface;
a receptacle formed in the body and configured to receive a portion of the fiber optic cable;
a cavity formed in a tip of the body; and
at least two openings formed in the exterior surface of the body and each of at least two openings are connected to the cavity, wherein the at least two openings comprise an axial opening at a leading point of the body and at least one peripheral opening, and wherein each of the axial opening and the at least one peripheral opening are separate from each other and comprise a distinct entrance and/or exit into the cavity.

2. The protective cap of claim 1 , wherein the at least one peripheral opening comprises two peripheral openings.

3. The protective cap of claim 1 , wherein the two peripheral openings are aligned with each other on opposite sides of the body.

4. The protective cap of claim 1 , wherein the at least two openings are elongated.

5. The protective cap of claim 4 , wherein the at least two openings are elongated in the same plane.

6. The protective cap of claim 1 , further comprising a guide element inside of the cavity configured to guide a pull cord inserted into one of the at least two openings out of another of the at least two openings.

7. The protective cap of claim 6 , wherein the guide element comprises an angled surface leading to the another of the at least two openings.

8. The protective cap of claim 6 , wherein the guide element comprises a pair of angled surfaces, each leading to an opening of the at least two openings.

9. The protective cap of claim 8 , wherein the angled surfaces are aligned in the same plane and form an acute angle with each other.

10. The protective cap of claim 9 , wherein the guide element further comprises a rounded tip that transitions into the pair of angled surfaces.

11. The protective cap of claim 1 , wherein the cavity is formed as a rectangular slot.

12. The protective cap of claim 1 , wherein the tip of the body has a rounded or ballistic shape.

13. The protective cap of claim 1 , wherein the protective cap includes projections configured to fit into notches on a ferrule retainer.

14. The protective cap of claim 1 , further comprising an attachment feature, wherein the attachment feature comprises a hollow space cavity formed in the leading tip, the cavity comprising an elongated axial distal opening in the leading tip and at least one elongated side opening formed in an exterior side surface of the protective cap, each of the elongated axial distal opening and the at least one elongated side opening connected to the cavity such that a pull cord may enter one of the openings and exit another of the openings to attach to the protective cap.
