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

What is claimed is:

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 at least one tear tab configured to be pulled by a user to facilitate tool-less removal of the installation device from the preterminated optical fiber drop cable.

2. The cable 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 cable assembly of claim 1 , 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.

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

5. The cable assembly of claim 1 , wherein the installation device comprises a pushing device that includes a rigid tube configured to push the connector body through a straight passage, wherein the straight passage has a diameter of less than 0.4 inches.

6. The cable assembly of claim 1 , wherein the installation device comprises a pushing device that includes a rigid tube configured to push the connector body through a straight passage, wherein the straight passage is less than 20% larger than the connector body.

7. The cable assembly of claim 1 , wherein a first end of the cable assembly can fit through a ⅜ inch hole.

8. The cable assembly of claim 1 , wherein the installation device comprises a protection device disposed over the connector body at the terminal end of the preterminated optical fiber drop cable to protect an exposed, unjacketed portion of the preterminated optical fiber drop cable adjacent to a back end of the connector body.

9. The cable assembly of claim 1 , wherein the attachment portion comprises a pre-expanded collapsible sleeve with at least one longitudinal slit.

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

11. 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 at least one longitudinal slit extending from a first end of the sleeve portion to a second end of the sleeve portion to provide tool-less removal of the installation device from the preterminated optical fiber drop cable.

12. The cable assembly of claim 11 , 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.

13. The cable assembly of claim 11 , wherein the installation device comprises a pushing device.

14. The cable assembly of claim 11 , wherein the installation device comprises a protection device disposed over the connector body at the terminal end of the preterminated optical fiber drop cable to protect an exposed, unjacketed portion of the preterminated optical fiber drop cable adjacent to a back end of the connector body.

15. A method for installing a fiber optic cable assembly, the method comprising:
routing a first end of a cable assembly from an exterior location through a building entrance point into an interior location of a building, wherein the first end of the cable assembly includes (i) a preterminated optical fiber drop cable having a connector body mounted on a terminal end of the preterminated optical fiber drop cable, and (ii) an installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion; and
toollessly removing the installation device from the preterminated optical fiber drop cable within the interior location of the building.

16. The method of claim 15 , 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.

17. The method of claim 15 , 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.

18. The method of claim 15 , wherein the installation device comprises a pushing device.

19. The method of claim 15 , wherein the installation device comprises a pushing device that includes a rigid tube, and the routing of the first end of the cable assembly includes pushing the connector body with the rigid tube through a straight passage, wherein the straight passage is characterized by one of the following features (a) or (b): (a) the straight passage has a diameter of less than 0.4 inches, or (b) the straight passage has a diameter less than 20% larger than the connector body.

20. The method of claim 15 , wherein:
the attachment portion includes at least one tear tab; and
the toollessly removing of the installation device from the preterminated optical fiber drop cable comprises pulling the at least one tear tab.
