Fiber optic cable assemblies with cap apparatuses for sealing optical fiber connectors and associated methods

1. A method for cleaning at least an end face of a ferrule of an fiber optic connector and enclosing at least the end face of the ferrule in a cap apparatus, the method comprising:

mounting a body of the cap apparatus to the fiber optic connector, wherein the body has opposite proximal and distal ends between which a cavity extends, the proximal end defining a first opening to the cavity, the distal end defining a second opening to the cavity, and the mounting being comprised of causing relative movement between the body and the fiber optic connector so that at least a portion of the fiber optic connector extends through the first opening;

cleaning at least the end face of the ferrule while the body is mounted to the fiber optic connector; and

then, sealing closed the cavity of the cap apparatus with a sealing apparatus so that at least the cleaned end face of the ferrule is positioned in the sealed closed cavity;

wherein the cap apparatus further includes a cover mounted to the body and movable between a closed configuration in which the cover at least partially obstructs the second opening and an open configuration in which at least a portion of the cover is farther away from the second opening than when the cover is in the closed configuration, and further wherein the cleaning is performed when the cover is in the open configuration; and

wherein the sealing closed comprises applying the sealing apparatus to the body of the cap apparatus before moving the cover from the open configuration to the closed configuration.

2. The method of claim 1 , wherein the cleaning is further comprised of cleaning at least a portion of an interior of the body.

3. The method of claim 1 , wherein the cleaning is further comprised of cleaning at least a portion of the sealing apparatus.

4. The method of claim 1 , wherein the sealing apparatus comprises an adhesive tape that at least partially obstructs the second opening of the body when the adhesive tape is applied to the body.

5. The method of claim 4 , wherein an exterior of the body comprises opposite first and second sides, and wherein applying the sealing apparatus to the body comprises:

engaging a first area of adhesive material of the adhesive tape against the first side of the exterior of the body; and

engaging a second an area of adhesive material of the adhesive tape against the second side of the exterior of the body.

6. The method of claim 4 , wherein the second opening is sealed closed by the adhesive tape.

7. The method of claim 1 , wherein the sealing closed is comprised of at least partially obstructing the second opening of the body with the sealing apparatus.

8. The method of claim 1 , further comprising:

removing the cap apparatus from the fiber optic connector after the cavity of the cap apparatus has been sealed closed for a period of time; and

inserting the fiber optic connector into an adapter without further cleaning the end face of the ferrule.

9. The method of claim 8 , wherein inserting the fiber optic connector into an adapter further comprises aligning the ferrule of the fiber optic connector with a ferrule of a similar fiber optic connector using an alignment sleeve within the adapter.

10. The method of claim 1 , wherein the end face of the ferrule is spaced from the sealing apparatus when the cover is in the closed configuration.

11. The method of claim 1 , wherein mounting the body of the cap apparatus to the fiber optic connector comprises positioning the end face of the ferrule closer to the second opening than the first opening.

12. The method of claim 1 , wherein the end face of the ferrule is spaced from the cover by a distance S that is less than 5 mm after the cover is moved to the closed configuration.

13. A method for cleaning at least an end face of a ferrule of an fiber optic connector and enclosing at least the end face of the ferrule in a cap apparatus, the method comprising:

mounting a body of the cap apparatus to the fiber optic connector, wherein the body has opposite proximal and distal ends between which a cavity extends, the proximal end defining a first opening to the cavity, the distal end defining a second opening to the cavity, and the mounting being comprised of causing relative movement between the body and the fiber optic connector so that at least a portion of the fiber optic connector extends through the first opening;

cleaning at least the end face of the ferrule while the body is mounted to the fiber optic connector; and

sealing closed the cavity of the cap apparatus with a sealing apparatus so that at least the cleaned end face of the ferrule is positioned in the sealed closed cavity;

wherein:

the sealing apparatus comprises an area of adhesive material that both confronts the end face of the ferrule and is spaced apart from the end face of the ferrule when the cover is in the closed configuration;

the sealing apparatus comprises adhesive tape, and the adhesive tape comprises the area of adhesive material; and

the second opening is sealed closed by the adhesive tape;

wherein the cap apparatus further includes a cover movable between a closed configuration in which the cover at least partially obstructs the second opening and an open configuration in which at least a portion of the cover is farther away from the second opening than when the cover is in the closed configuration, and further wherein the cleaning is performed when the cover is in the open configuration;

wherein the sealing closed comprises applying the sealing apparatus to the body or the cover of the cap apparatus before moving the cover from the open configuration to the closed configuration.

14. The method of claim 13 , wherein the cover is pivotably connected to the body to move from the open configuration to the closed configuration.

15. The method of claim 13 , further comprising:

removing the cap apparatus from the fiber optic connector after the cavity of the cap apparatus has been sealed closed for a period of time; and

inserting the fiber optic connector into an adapter without further cleaning the end face of the ferrule.

16. The method of claim 15 , wherein inserting the fiber optic connector into an adapter further comprises aligning the ferrule of the fiber optic connector with a ferrule of a similar fiber optic connector using an alignment sleeve within the adapter.

17. The method of claim 13 , wherein the end face of the ferrule is spaced from the sealing apparatus when the cover is in the closed configuration.
