Fiber optic adapter assembly

1. A fiber optic adapter assembly of a telecommunications enclosure, the assembly defining a longitudinal axis aligned with a connector port of the enclosure and comprising:

a first housing configured to snap connect to a second housing with a pair of retaining clips;

an adapter module including an adapter body and an annular flange extending radially outwardly from the adapter body and the longitudinal axis, the adapter module having at least a portion positioned inside the first housing, the adapter module further including a barrel portion configured to align ferrules terminating first and second optical fibers parallel to the longitudinal axis; and

a spring positioned inside the first housing and fully surrounding the longitudinal axis and an outer surface of a portion of the adapter module, the spring biasing the adapter module parallel to the axis in a direction towards the connector port of the enclosure, the spring being captured between an inner shoulder defined by the first housing and the annular flange of the adapter module;

wherein the spring and the flange are positioned entirely within an internal cavity of the first housing; and

wherein the fiber optic adapter assembly is configured to mount to the telecommunications enclosure such that at least a portion of the fiber optic adapter assembly is positioned within an interior of the enclosure.

2. The fiber optic adapter assembly of claim 1 , wherein a portion of the adapter module extends through an open end of the first housing.

3. The fiber optic adapter assembly of claim 1 , wherein a portion of the barrel portion is within the first housing and another portion of the barrel portion is positioned not within the first housing.

4. The fiber optic adapter assembly of claim 1 ,

wherein the second housing includes the retaining clips; and

wherein the first housing includes slots that receive tabs of the retaining clips.

5. The fiber optic adapter assembly of claim 1 , wherein the adapter module is configured to be longitudinally slidable through an open end of the first housing.

6. The fiber optic adapter assembly of claim 5 ,

wherein the first housing includes a first guide element; and

wherein the adapter module includes a second guide element correspondingly engaging the first guide element and configured to guide the adapter module to longitudinally move through the open end of the first housing.

7. The fiber optic adapter assembly of claim 1 , wherein the adapter module includes a pair of latching arms configured to interlock with a fiber optic connector supporting one of the ferrules.

8. The fiber optic adapter assembly of claim 1 , wherein the adapter module includes a ferrule alignment sleeve positioned within the barrel portion and configured to receive the ferrules from opposite directions.

9. The fiber optic adapter assembly of claim 1 , further comprising an axial stopper configured to limit movement in a first direction parallel to the axis of the adapter module within the first housing.

10. The fiber optic adapter assembly of claim 9 , further comprising another axial stopper configured to limit movement in a second direction opposite the first direction of the adapter module within the first housing.

11. The fiber optic adapter assembly of claim 1 , wherein the fiber optic adapter assembly is configured to mount to the telecommunications enclosure such that a portion of the fiber optic adapter assembly is positioned at an exterior of the enclosure.

12. The fiber optic adapter assembly of claim 1 , wherein the fiber optic adapter assembly is configured to mount to the telecommunications enclosure by pushing the first housing towards the connector port parallel to the axis.

13. The fiber optic adapter assembly of claim 1 , wherein a portion of the adapter module is positioned within the second housing.

14. The fiber optic adapter assembly of claim 1 , wherein the second housing includes internal threads.
