Abstract

An interface converter is provided for mechanically and optically coupling a non-ruggedized fiber optic connector with a ruggedized adapter port. In a preferred embodiment, the interface converter attaches to an SC fiber optic connector and together form a converted fiber optic connector compatible with the ruggedized adapter port. In certain embodiments, a retractable release sleeve may be removed from the SC fiber optic connector prior to attaching the interface converter. In certain embodiments, the interface converter may be inserted into the ruggedized adapter port prior to being attached to the SC fiber optic connector.

mounting a second piece of the converter to the first piece of the converter;

engaging a slot of the converter with the retention shoulder of the fiber optic connector; and

positioning a threaded member of the converter at least partially over an exterior of the mounted first and second pieces of the converter;

wherein the converter includes a first paddle that extends to a distal end of the converter.

2. The method of claim 1, wherein the slot of the converter is included on the first piece of the converter.

3. The method of claim 2, wherein the slot of the converter is also included on the second piece of the converter.

4. The method of claim 1, wherein the first piece of the converter includes the first paddle and the second piece of the converter includes a second paddle that extends to the distal end of the converter and wherein the first and the second paddles are generally positioned opposite each other about a ferrule of the fiber optic connector when the first piece is mounted to the portion of the fiber optic connector and the second piece is mounted to the first piece of the converter.

5. The method of claim 1, wherein the fiber optic connector includes a pair of the retention shoulders and the first piece of the converter includes a pair of the slots.

6. The method of claim 5, wherein the second piece of the converter also includes the pair of the slots.

7. The method of claim 1, wherein the first piece of the converter is a first half-piece and the second piece of the converter is a second half-piece and wherein the first and the second half-pieces abut each other at a plane extending parallel to a central axis of the fiber optic connector.

8. The method of claim 7, wherein the second half-piece of the converter is mounted to the first half-piece of the converter by a tongue-and-groove connection.

9. The method of claim 8, wherein a tongue of the tongue-and-groove connection is included on the first half-piece and a groove of the tongue-and-groove connection is included on the second half-piece.

10. The method of claim 8, wherein the tongue-and-groove connection between the first and the second half-pieces is made by relative movement between the first and the second half-pieces in a direction parallel to the central axis of the fiber optic connector.

11. The method of claim 7, wherein the second half-piece of the converter is mounted to the first half-piece of the converter by a latching clip and receiver connection.

12. The method of claim 11, wherein the slot of the converter includes a first slot portion on the first piece of the converter and includes a second slot portion on the second piece of the converter, wherein the first slot portion engages the retention shoulder of the fiber optic connector when the first piece of the converter is mounted over the portion of the fiber optic connector, and wherein the second slot portion engages the retention shoulder of the fiber optic connector when the second piece of the converter is mounted to the first piece of the converter.

13. The method of claim 11, wherein a latching clip of the latching clip and receiver connection is included on the first half-piece and a receiver of the latching clip and receiver connection is included on the second half-piece.

14. The method of claim 11, wherein the latching clip and receiver connection between the first and the second half-pieces is made by relative movement between the first and the second half-pieces in a direction perpendicular to the central axis of the fiber optic connector.

15. The method of claim 1, further comprising prepositioning the threaded member of the converter over the fiber optic connector prior to the mounting of the first piece of the converter over the portion of the fiber optic connector.

16. The method of claim 1, further comprising removal of a release sleeve from the fiber optic connector prior to the mounting of the first piece of the converter over the portion of the fiber optic connector.

17. The method of claim 5, wherein the retention shoulders of the fiber optic connector extend in a direction perpendicular to a central axis of the fiber optic connector and the first piece of the converter is mounted to the portion of the fiber optic connector by relative movement between the first piece and the fiber optic connector in the direction perpendicular to the central axis of the fiber optic connector.

18. The method of claim 1, wherein a portion of the exterior of the mounted first and the second pieces of the converter defines a substantially cylindrical surface, wherein the threaded member includes a substantially cylindrical interior surface, and wherein the substantially cylindrical interior surface of the threaded member pilots the threaded member on the substantially cylindrical surface when the threaded member is positioned on the exterior of the mounted first and second pieces.

19. The method of claim 1, wherein the mounted first and second pieces of the converter define a shoulder, wherein the threaded member includes an abutting surface, and wherein the abutting surface of the threaded member is adapted to abut the shoulder defined by the mounted first and second pieces.

20. The method of claim 4, wherein the first and the second paddles are adapted to provide a keying function that rotationally orients the converter and thereby orients the converted fiber optic connector when the converted fiber optic connector is connected to a port of a fiber optic adapter.

21. A method of converting a fiber optic connector that is adapted for connection to a first fiber optic adapter including a latch to a converted fiber optic connector that is adapted for connection to a second fiber optic adapter including threads, the fiber optic connector including a retention shoulder adapted to latch to the latch of the first fiber optic adapter, the method comprising:

providing the fiber optic connector and a converter;

mounting a first piece of the converter over a first portion of the fiber optic connector, the first piece of the converter including a first paddle that extends to a distal end of the first piece;

mounting a second piece of the converter over a second portion of the fiber optic connector, the second piece of the converter including a second paddle that extends to a distal end of the second piece; and

positioning a threaded member of the converter over a portion of the mounted first and second pieces of the converter;

wherein the converter includes a slot that engages the retention shoulder of the fiber optic connector; and

wherein the first and the second paddles are generally positioned opposite each other about a ferrule of the fiber optic connector when the first and the second pieces are mounted over the first and the second portions of the fiber optic connector.
