wherein the single biasing member is captured between an inner shoulder defined around an opening at the interior end of the first housing and the annular flange of the adapter module; and

wherein the single biasing member and the flange are positioned entirely within an internal cavity of the first housing.

2. The fiber optic adapter assembly of claim 1 , further comprising a ferrule holder that is at least partially positioned in the adapter body, and wherein the single biasing member partially surrounds the ferrule holder inside the first housing.

3. The fiber optic adapter assembly of claim 2 , further comprising a barrel portion on the ferrule holder, the barrel portion being configured to receive the ferrules of the first and second fiber optic cable connectors, and wherein the single biasing member partially surrounds the barrel portion inside the first housing.

4. The fiber optic adapter assembly of claim 2 , further comprising latching arms on the ferrule holder, wherein the latching arms are configured to selectively engage at least one of the first and second fiber optic cable connectors when inserted in the adapter module, and wherein the single biasing member partially surrounds the latching arms inside the first housing.

5. The fiber optic adapter assembly of claim 1 , further comprising a ferrule alignment sleeve positioned in the adapter module.

6. The fiber optic adapter assembly of claim 1 , wherein the first housing includes an axial stopper configured to limit an axial movement of the adapter module within the first housing, and the single biasing member surrounds the axial stopper inside the first housing.

7. The fiber optic adapter assembly of claim 1 , wherein the adapter module includes a ferrule alignment sleeve, and the single biasing member at least partially surrounds the ferrule alignment sleeve inside the first housing.

8. The fiber optic adapter assembly of claim 1 , further comprising the second housing, wherein the single biasing member is concentrically aligned with the adapter module in the first housing, and wherein the first housing and the second housing interlock by snap connection to secure the first housing to a bulkhead of the enclosure.

9. The fiber optic adapter assembly of claim 8 , wherein the first housing is configured to be positioned on a first side of the bulkhead, the second housing is configured to be positioned on an opposite second side of the bulkhead, and wherein the first housing defines an exterior, ruggedized port for receiving at least one of the first and second fiber optic cable connectors, and the second housing defines an interior, non-ruggedized port for receiving another one of the first and second fiber optic cable connectors.

10. The fiber optic adapter assembly of claim 8 , wherein the single biasing member biases the adapter module in a direction toward the second housing, and is compressible in an opposite direction within the first housing component.

11. The fiber optic adapter assembly of claim 10 , wherein the single biasing member provides an even biasing of the adapter module within the first housing.

12. The fiber optic adapter assembly of claim 8 , wherein the second housing includes a sealing flange portion, the sealing flange portion holding a sealing member to provide a radial sealing of the fiber optic adapter assembly against the bulkhead.

13. The fiber optic adapter assembly of claim 8 , wherein the second housing includes a plurality of retaining clips to removably engage corresponding slots on the first housing.

14. The fiber optic adapter assembly of claim 1 , wherein the single biasing member is concentrically aligned with the adapter module.

15. The fiber optic adapter assembly of claim 1 , wherein the single biasing member is a compression coil spring.

16. The fiber optic adapter assembly of claim 1 , wherein the interior end includes a first opening configured to receive a Subscription Channel (SC) connector, and the exterior end includes a second opening configured to receive a ruggedized fiber optic connector.

17. A fiber optic connection system comprising:

an enclosure defining an interior of the enclosure and an exterior of the enclosure;

a fiber optic adapter assembly that is configured to receive a first fiber optic connector at a first adapter end and a second fiber optic connector at a second adapter end, the fiber optic adapter assembly comprising:

a first housing;

a second housing snap connected to the first housing to secure the first housing to the enclosure in the interior of the enclosure;

an adapter module floating inside the first housing and configured to align ferrules of the first and second fiber optic cable connectors; and

a single biasing member surrounding a portion of the adapter module inside the first housing, the single biasing member biasing the adapter module in a direction toward the first adapter end and being compressible in a direction toward the second adapter end, the first adapter end being positioned in the interior of the enclosure;

wherein the fiber optic adapter assembly is configured to align an optical fiber of the first fiber optic connector with an optical fiber of the second fiber optic connector when the first and second fiber optic connectors are inserted into the first and second adapter ends,

wherein the adapter module includes an adapter body and an annular flange extending radially outwardly from the adapter body;

wherein the single biasing member surrounds the adapter body inside the first housing;

wherein the single biasing member is captured between an inner shoulder defined around an opening at the first end of the first housing and the annular flange of the adapter module; and

wherein the single biasing member and the flange are positioned entirely within an internal cavity of the first housing.

18. A fiber optic adapter assembly comprising:

an adapter housing;

an adapter module floating inside the adapter housing and configured to align ferrules of first and second fiber optic cable connectors; and

a single biasing member surrounding a portion of the adapter module inside the adapter housing, the single biasing member biasing the adapter module in a direction toward an exterior end and being compressible in a direction toward an interior end,

wherein the adapter housing includes an axial stopper configured to limit an axial movement of the adapter module within the adapter housing, and the single biasing member surrounds the axial stopper inside the adapter housing.
