Abstract

A telecommunications cable includes a distribution cable, a tether, and a tube. One end of a length of optical fiber optically couples to the distribution cable and the opposite end of the length of optical fiber optically couples to the tether cable. The tube is mounted over the length of optical fiber. The tube defines an opening adjacent one end of the tube. The tube includes fingers adjacent the opening having sufficient flexibility to enable the one end of the tube to wrap around buffer tubes of the distribution cable.

Claims

1. A telecommunications cable comprising:

a distribution cable including a cable jacket and at least one buffer tube positioned within the cable jacket, the distribution cable including a breakout location where a portion of the distribution cable jacket has been removed to form a stripped region and where the at least one buffer tube includes a fiber access location;

a tether including a tether jacket, a tether buffer tube positioned within the tether jacket;

a length of optical fiber extending from a first end to a second end, the first end being optically coupled to the distribution cable and the second end being optically coupled to the tether; and

a tube having a hollow body positioned about the length of optical fiber, the body defining an opening adjacent a first end of the body, the body being slit from the first end of the body to the opening to form first and second fingers, the fingers being configured to flex sufficiently to wrap around the at least one buffer tube of the distribution cable adjacent the fiber access location.

2. The telecommunications cable of claim 1, wherein a second, opposite end of the tube is positioned adjacent the tether buffer tube.

3. The telecommunications cable of claim 1, wherein the tube is formed from polyethylene.

4. The telecommunications cable of claim 1, wherein the tube is formed from Fluorinated Ethylene Propylene.

5. The telecommunications cable of claim 1, wherein the tube has a diameter of about ⅜

^th of an inch.

6. The telecommunications cable of claim 1, wherein the tube is secured to the at least one buffer tube of the distribution cable using Aluminum tape.

7. The telecommunications cable of claim 1, wherein the telecommunications cable is sized to be pulled through a conduit having a 1.25 inch inner diameter.

8. The telecommunications cable of claim 1, wherein the tether is a drop cable.

9. The telecommunications cable of claim 1, wherein the opening in the tube is defined by five sides.

10. The telecommunications cable of claim 1, wherein the first end of the tube includes a periphery.

11. The telecommunications cable of claim 10, wherein the tube includes a notch in the periphery of the first end of the tube adjacent the opening.

12. The telecommunications cable of claim 1, wherein the tube has a first length and the stripped region has a second length, and wherein the first length is about one inch less than the second length.
