Abstract

An optical connector assembly having a connector housing with a first and second end. First end accepts a ferrule assembly, and second end accepts a retention assembly. There is a longitudinal bore from a distal to proximal end of connector. Bore accepts a POF optical fiber therein at distal end and fiber is inserted proximally until fiber bottoms-out at proximal end of ferrule. Retention body accepts one or more retention caps, or retention body contains at least one retention wing set to secure fiber to connector.

Claims (16)

1. A fiber optic connector comprising:

a connector housing having a proximal end and a distal end; and

a ferrule configured to accept an optical fiber of an optical cable, the ferrule is positioned at the proximal end of the connector housing;

a backpost comprising a first set of wings at a proximal end, a second set of wings at a distal end, and a retention thread,

wherein upon assembly of the fiber optic connector, the first set of wings is configured to directly clamp the optical fiber, the second set of wings is configured to clamp a cable jacket of the optical cable, and the retention thread is configured to secure strength members of the optical cable.

2. The fiber optic connector as set forth in claim 1 , wherein the first set of wings is configured to clamp the optical fiber within the connector housing.

3. The fiber optic connector as set forth in claim 2 , further comprising a retention cap comprising inner threads.

4. The fiber optic connector as set forth in claim 3 , wherein a clamp is applied to the strength members between the inner threads and the retention thread.

5. The fiber optic connector as set forth in claim 1 , wherein the ferrule is a single-fiber ferrule.

6. The fiber optic connector as set forth in claim 1 , wherein the backpost is formed from multiple components that are assembled together to form the backpost.

7. The fiber optic connector as set forth in claim 6 , wherein said multiple components includes a proximal body forming the first set of wings and a distal body forming the second set of wings.

8. The fiber optic connector as set forth in claim 7 , wherein the proximal body further defines the retention thread.

9. The fiber optic connector as set forth in claim 7 , wherein the proximal body is formed from first and second half-body portions.

10. The fiber optic connector as set forth in claim 7 , wherein the distal body is partially received in the proximal body.

11. The fiber optic connector as set forth in claim 1 , wherein the ferrule is configured accept a polymer optical fiber.

12. The fiber optic connector as set forth in claim 1 , wherein the first set of wings is configured to directly engage an unjacketed portion of the optical fiber.
