Abstract

A fiber optic connector for a plurality of optical fibers includes: a housing portion, a ferrule assembly at least partially disposed in the housing portion, a spring push positioned behind the ferrule, and a spring positioned between the spring push and ferrule. The ferrule assembly includes a ferrule defining an end face of the fiber optic connector and having a plurality of bores arranged in at least two linear rows. The ferrule assembly also includes a ferrule boot coupled to the ferrule, with the ferrule boot including a fiber alignment portion and a cover portion. The fiber alignment portion defines a first groove for a first row of the optical fibers and a second groove for a second row of the optical fibers.

First claim

We claim:

1. A fiber optic connector for a plurality of optical fibers, comprising:
a housing portion;
a ferrule assembly at least partially disposed in the housing portion, the ferrule assembly comprising:
a ferrule having a plurality of bores arranged in at least two linear rows, the ferrule defining an end face of the fiber optic connector; and
a ferrule boot coupled to the ferrule, the ferrule boot including a fiber alignment portion and a cover portion, wherein the fiber alignment portion defines a first groove for a first row of the optical fibers and a second groove for a second row of the optical fibers;

a spring push positioned behind the ferrule; and
a spring positioned between the spring push and ferrule;
wherein the optical fibers can pass through an opening in the spring, through the ferrule boot, and into the ferrule;
wherein the cover portion comprises a substantially C-shaped cross section and is removably secured to an exterior portion of the fiber alignment portion to secure the first and second rows of optical fibers in the respective first and second grooves.

2. The fiber optic connector of claim 1 , wherein the fiber alignment portion comprises at least three extension portions to define the first and second grooves between the at least three extension portions.

3. The fiber optic connector of claim 2 , wherein the at least three extension portions form a substantially E-shaped cross section of the fiber alignment portion.

4. The fiber optic connector of claim 2 , wherein the at least three extension portions form a substantially S-shaped cross section of the fiber alignment portion.

5. The fiber optic connector of claim 2 , wherein the fiber alignment portion comprises more than three extension portions to define at least one additional groove for at least one additional row of optical fibers.

6. The fiber optic connector of claim 1 , wherein the first and second grooves each comprise a plurality of alignment slots for receiving individual optical fibers, wherein the plurality of alignment slots are color coded.

7. The fiber optic connector of claim 1 , wherein the fiber alignment portion comprises an alignment feature that is integral to the fiber alignment portion and extends from the fiber alignment portion to abut with the ferrule.

8. The fiber optic connector of claim 7 , wherein the alignment feature extends from the fiber alignment portion to abut with an exterior portion of the ferrule.

9. The fiber optic connector of claim 7 , wherein the alignment feature extends from the fiber alignment portion to abut with an interior surface of the ferrule.

10. A fiber optic connector, comprising:
a housing portion;
a ferrule assembly at least partially disposed in the housing portion, the ferrule assembly comprising:
a ferrule having a plurality of bores arranged in at least two linear rows, the ferrule defining an end face of the fiber optic connector; and
a ferrule boot coupled to the ferrule, the ferrule boot including a fiber alignment portion and a cover portion;

a spring push positioned behind the ferrule; and
a spring positioned between the spring push and ferrule;
a plurality of optical fibers arranged in at least a first row and a second row, wherein:
the fiber alignment portion of the ferrule boot defines a first groove for the first row of optical fibers and a second groove for the second row of optical fibers:
the optical pass through an opening in the spring, through the ferrule boot, and into the ferrule; and
the cover portion of the ferrule boot comprises a substantially C-shaped cross section and is removably secured to an exterior portion of the fiber alignment portion to secure the first and second rows of optical fibers in the respective first and second grooves.

11. The fiber optic connector of claim 10 , wherein the fiber alignment portion comprises at least three extension portions to define the first and second grooves between the at least three extension portions.

12. The fiber optic connector of claim 11 , wherein the at least three extension portions form a substantially E-shaped or substantially S-shaped cross section of the fiber alignment portion.

13. The fiber optic connector of claim 11 , wherein the fiber alignment portion comprises more than three extension portions to define at least one additional groove for at least one additional row of optical fibers.

14. A fiber optic connector for a plurality of optical fibers, comprising:
a housing portion;
a ferrule assembly at least partially disposed in the housing portion, the ferrule assembly comprising:
a ferrule having a plurality of bores arranged in at least one linear row, the ferrule defining an end face of the fiber optic connector; and
a ferrule boot coupled to the ferrule, the ferrule boot including a fiber alignment portion and a cover portion, wherein the fiber alignment portion defines at least one groove for the at least one row of the optical fibers;

a spring push positioned behind the ferrule; and
a spring positioned between the spring push and ferrule;
wherein the optical fibers can pass through an opening in the spring, through the ferrule boot, and into the ferrule;
wherein the cover portion comprises a substantially C-shaped cross section and is removably secured to an exterior portion of the fiber alignment portion to secure the at least one linear row of optical fibers in the at least one groove.

15. The fiber optic connector of claim 14 , wherein the at least one groove each comprise a plurality of alignment slots for receiving individual optical fibers, wherein the plurality of alignment slots are color coded.

16. The fiber optic connector of claim 14 , wherein the fiber alignment portion comprises an alignment feature that is integral to the fiber alignment portion and extends from the fiber alignment portion to abut with the ferrule.

17. The fiber optic connector of claim 16 , wherein the alignment feature extends from the fiber alignment portion to abut with an exterior portion of the ferrule.

18. The fiber optic connector of claim 16 , wherein the alignment feature extends from the fiber alignment portion to abut with an interior surface of the ferrule.

19. A fiber optic connector, comprising:
a housing portion;
a ferrule assembly at least partially disposed in the housing portion, the ferrule assembly comprising:
a ferrule having a plurality of bores arranged in at least two linear rows, the ferrule defining an end face of the fiber optic connector; and
a ferrule boot coupled to the ferrule, the ferrule boot including a fiber alignment portion and a cover portion;

a spring push positioned behind the ferrule; and
a spring positioned between the spring push and ferrule;
a plurality of optical fibers arranged in at least one linear row, wherein:
the fiber alignment portion of the ferrule boot defines at least one groove for the at least one linear row of optical fibers:
