Fiber optic adapter
The present disclosure relates to a fiber optic connector for use with a fiber optic adapter. The fiber optic connector includes a connector housing having an end defining a plug portion. A ferrule assembly is mounted at least partially within the connector housing. The ferrule assembly includes a ferrule located at the plug portion of the connector housing. A sealing member is mounted about an exterior of the connector housing for providing a seal between the connector housing and the adapter. The fiber optic connector further includes first and second separate retaining mechanism for retaining the fiber optic connector within the fiber optic adapter.
1. A fiber optic adapter comprising:
an outer housing having a first axial end portion defining a first adapter port and a second axial end portion defining a second adapter port;
an adapter assembly mounted within the outer housing in a manner that prohibits the adapter assembly from floating within the outer housing, the adapter assembly including a split sleeve adapted to receive a ferrule of a first fiber optic connector inserted into the first adapter port and a ferrule of a second fiber optic connector inserted into the second adapter port and to maintain alignment between fibers of the first and second fiber optic connectors; and
a coupler adapted to rotatably mount around an exterior of the outer housing and to mechanically connect the fiber optic adapter to a structure, wherein the coupler is a mounting nut that rotates around the outer housing to engage or disengage the structure.
2. The fiber optic adapter of claim 1 , wherein the outer housing defines a shoulder, and the coupler is structured to capture the structure between the shoulder and the coupler to secure the fiber optic adapter to the structure.
3. The fiber optic adapter of claim 1 , wherein the structure is an enclosure wall.
4. The fiber optic adapter of claim 1 , wherein the first axial end portion includes a twist-to-lock fastening element to secure the first fiber optic connector in the first adapter port.
5. The fiber optic adapter of claim 1 , wherein the first adapter port includes an annular sealing surface structured to engage a sealing member mounted around an exterior of the first fiber optic connector when the first fiber optic connector is inserted into the first adapter port.
6. The fiber optic adapter of claim 5 , wherein the annular sealing surface is structured to provide an internal environmental seal between the fiber optic adapter and the first fiber optic connector when the first fiber optic connector is inserted into the first adapter port.
7. The fiber optic adapter of claim 5 , wherein the first adapter port includes an angled diameter transition that decreases an internal diameter of the first adapter port to a diameter defined by the annular sealing surface.
8. The fiber optic adapter of claim 5 , wherein the annular sealing surface defines a diameter less than or equal to 15 millimeters.
9. The fiber optic adapter of claim 5 , wherein the annular sealing surface defines a diameter less than or equal to 12.5 millimeters.
10. The fiber optic adapter of claim 5 , wherein the annular sealing surface defines a diameter less than or equal to 10 millimeters.
11. The fiber optic adapter of claim 1 , wherein the adapter assembly is structured to snap-fit within the outer housing.
12. The fiber optic adapter of claim 1 , wherein the outer housing includes oppositely positioned latches for securing the adapter assembly within the outer housing, wherein the oppositely positioned latches include retention tabs, and wherein the retention tabs prevent the adapter assembly from floating within the outer housing.
13. The fiber optic adapter of claim 1 , wherein the adapter assembly includes a connector retention clip having a pair of latching arms that interlock with the second fiber optic connector when inserted within the second adapter port, and the connector retention clip further includes a cylindrical receptacle for receiving a first end of the split sleeve.
14. The fiber optic adapter of claim 13 , wherein the adapter assembly further includes a backing piece having a cylindrical receptacle, and a second end of the split sleeve is received within the cylindrical receptacle of the backing piece.
15. The fiber optic adapter of claim 14 , wherein the retention clip and the backing piece are secured together to retain the split sleeve between the retention clip and the backing piece, and wherein the split sleeve is mounted between the retention clip and the backing piece to float within the cylindrical receptacles of the retention clip and the backing piece to provide proper alignment between the ferrules of the first and second fiber optic connectors.
16. The fiber optic adapter of claim 1 , wherein the second axial end portion includes a keying slot structured to receive an alignment structure of the second fiber optic connector to ensure that the second fiber optic connector is inserted into the second adapter port at a proper orientation.
17. The fiber optic adapter of claim 1 , wherein the fiber optic adapter is ruggedized.
18. A fiber optic adapter comprising:
an outer housing having a first axial end portion defining a first adapter port and a second axial end portion defining a second adapter port;
an adapter assembly mounted within the outer housing in a manner that prohibits the adapter assembly from floating within the outer housing, the adapter assembly including a split sleeve adapted to receive a ferrule of a first fiber optic connector inserted into the first adapter port and a ferrule of a second fiber optic connector inserted into the second adapter port and to maintain alignment between fibers of the first and second fiber optic connectors; and
a coupler adapted to rotatably mount around an exterior of the outer housing and to mechanically connect the fiber optic adapter to a structure;
wherein the outer housing includes oppositely positioned latches for securing the adapter assembly within the outer housing, wherein the oppositely positioned latches include retention tabs that prevent the adapter assembly from floating within the outer housing.
19. A fiber optic adapter comprising:
an outer housing having a first axial end portion defining a first adapter port and a second axial end portion defining a second adapter port;
an adapter assembly mounted within the outer housing in a manner that prohibits the adapter assembly from floating within the outer housing, the adapter assembly including a split sleeve adapted to receive a ferrule of a first fiber optic connector inserted into the first adapter port and a ferrule of a second fiber optic connector inserted into the second adapter port and to maintain alignment between fibers of the first and second fiber optic connectors, the adapter assembly includes a connector retention clip having a pair of latching arms that interlock with the second fiber optic connector when inserted within the second adapter port, and the connector retention clip includes a cylindrical receptacle for receiving a first end of the split sleeve; and
a coupler adapted to rotatably mount around an exterior of the outer housing and to mechanically connect the fiber optic adapter to a structure.
