Abstract

A cable assembly is described that includes a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof, and a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes a pair of tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.

First claim

We claim:

1. A cable assembly, comprising:
a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof; and
a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.

2. The assembly of claim 1 , wherein the connector body is disposed within the installation device such that the installation device does not exert any tensile loading on the connector body when pushed or pulled.

3. The assembly of claim 1 , wherein the installation device is a push-pull device comprising a pulling sock and a pushing device separably attached to a front end of the pulling sock.

4. The assembly of claim 1 , wherein the installation device is a pushing device.

5. The assembly of claim 3 , wherein the pushing device is a rigid tube used to push the rigid connector body through a straight passage, wherein the passage has a diameter of less than 0.4 inches.

6. The assembly of claim 4 , wherein the pushing device is a rigid tube used to push the rigid connector body through a straight passage, wherein the passage has a diameter of less than 0.4 inches.

7. The assembly of claim 3 , wherein the pushing device is a rigid tube used to push the rigid connector body through a straight passage, wherein the passage is less 20% larger than the connector body.

8. The assembly of claim 4 , wherein the pushing device is a rigid tube used to push the rigid connector body through a straight passage, wherein the passage is less 20% larger than the connector body.

9. The assembly of claim 1 , wherein a first end of the assembly can fit through a ⅜ in. hole.

10. The assembly of claim 2 , wherein a first end of the assembly can fit through a ⅜ in. hole.

11. The assembly of claim 1 , wherein the installation device is a protection device disposed over a connector body at the preterminated end of the drop cable assembly to protect an exposed, unjacketed portion of the drop cable adjacent to a backend of the connector body.

12. The assembly of claim 1 , wherein the attachment portion is formed from a pre-expanded collapsible sleeve with one or more longitudinal slits.

13. The assembly of claim 9 , wherein the pre-expanded collapsible sleeve comprises a piece of adhesive-coated heat shrink tubing.

14. A cable assembly, comprising:
a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof; and
a removable installation device attached to the preterminated optical fiber drop cable, wherein the installation device comprises a push-pull device comprising a pulling sock and a pushing device separably attached to a front end of the pulling sock.

15. The assembly of claim 14 , wherein the pulling sock comprises a tubular body, a nose portion disposed at the front end of the tubular body portion, a flexible pulling loop attached to the tubular body portion by the nose portion, and an attachment portion attached to the other end of the tubular body portion opposite the nose portion.

16. The assembly of claim 15 , wherein the attachment portion is secured to a cable jacket of the fiber drop cable and includes tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.

17. The assembly of claim 15 , wherein the attachment portion is formed from a pre-expanded collapsible sleeve with one or more longitudinal slits.

18. The assembly of claim 16 , wherein the attachment portion is formed from a pre-expanded collapsible sleeve with one or more longitudinal slits.

19. The assembly of claim 17 , wherein the pre-expanded collapsible sleeve comprises a piece of adhesive-coated heat shrink tubing.

20. A cable assembly, comprising:
a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof; and
a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes a sleeve portion and an adhesive portion, wherein the sleeve portion includes two longitudinal slits extending from a first end of the sleeve to a second end of the sleeve to divide the sleeve into two half shell portions to provide tool-less removal of the installation device from the preterminated optical fiber drop cable.
