Abstract

An optical fiber connector and method for assembly and use are disclosed. The optical fiber connector is configured to have a small footprint so that the connector may be pushable or pullable through a conduit if use of a conduit may be needed. The connector may include a first number of connector components configured to fit through a conduit, and a second number of connector components that are configured to be installed to the first components, for example, after the connector is pushed or pulled through a conduit.

Claims (36)

1. A terminal end assembly for an optical fiber cable, the assembly comprising:

a first plurality of connector components configured to pass through a conduit; and

a second plurality of connector components configured to be installed around at least some of the first plurality of connector components after the first plurality of connector components is at least one of pushed and pulled through the conduit.

2. The terminal end assembly of claim 1 , wherein the first plurality of connector components comprises:

at least one ferrule for receiving and terminating an optical fiber of the optical fiber cable; and

a pulling eye retained on the terminal end of the optical fiber cable.

3. The terminal end assembly of claim 2 , wherein the pulling eye is removable.

4. The terminal end assembly of claim 2 , wherein the first plurality of connector components further comprises a protective tube arranged around the at least one ferrule.

5. The terminal end assembly of claim 4 , wherein the protective tube is formed from a low friction material.

6. The terminal end assembly of claim 4 , wherein the protective tube is formed from polytetrafluoroethylene.

7. The terminal end assembly of claim 4 , wherein the protective tube is retained via a friction fit.

8. The terminal end assembly of claim 2 , wherein the second plurality of connector components comprises at least one ferrule housing and an outer housing.

9. The terminal end assembly of claim 2 , wherein the first plurality of connector components further comprises a biasing member.

10. The terminal end assembly of claim 1 , wherein the first plurality of connector components has a maximum cross-sectional dimension of about 5 mm.

11. The terminal end assembly of claim 1 , wherein the conduit has an internal diameter of about 6 mm.

12. The terminal end assembly of claim 1 , wherein the terminal end assembly is configured for an LC-type connection assembly.

13. A method of manufacturing a terminal end assembly for an optical fiber cable, the method comprising:

providing a first plurality of connector components configured to pass through a conduit; and

providing a second plurality of connector components configured to be installed around at least some of the first plurality of connector components after the first plurality of connector components is pushed or pulled through the conduit.

14. The method of claim 13 , wherein providing the first plurality of connector components comprises:

providing at least one ferrule for receiving and terminating an optical fiber of the optical fiber cable; and

providing a pulling eye for retaining on the terminal end of the optical fiber cable.

15. The method of claim 14 , wherein the pulling eye is removable.

16. The method of claim 14 , wherein providing the first plurality of connector components further comprises arranging a protective tube around the at least one ferrule.

17. The method of claim 16 , wherein the protective tube is formed from a low friction material.

18. The method of claim 16 , wherein the protective tube is formed from polytetrafluoroethylene.

19. The method of claim 16 , further comprising retaining the protective tube via a friction fit.

20. The method of claim 14 , wherein providing the second plurality of connector components comprises providing at least one ferrule housing and an outer housing.

21. The method of claim 14 , wherein providing the first plurality of connector components further comprises providing a biasing member.

22. The method of claim 13 , wherein the first plurality of connector components has a maximum cross-sectional dimension of about 5 mm.

23. The method of claim 13 , wherein the conduit has an internal diameter of about 6 mm.

24. The method of claim 13 , wherein the terminal end assembly is configured for an LC-type connection assembly.

25. A method for installation of an optical fiber, the method comprising:

progressing a pre-terminated terminal end assembly through a conduit via at least one of pushing and pulling, the pre-terminated terminal end assembly comprising a first plurality of connector components configured to pass through the conduit; and

installing a second plurality of connector components around at least some of the first plurality of connector components after the first plurality of connector components is at least one of pushed and pulled through the conduit.

26. The method of claim 25 , wherein the first plurality of connector components comprises at least one ferrule and a pulling eye, and the second plurality of connector components comprises at least one ferrule housing and an outer housing.
