Abstract

A fiber optic telecommunications device includes an enclosure defining an interior. A first fiber optic adapter is provided at the enclosure. A spool is provided at an exterior of the enclosure. A fiber optic cable, which includes a first optical fiber, is wrapped around the spool. A first fiber optic connector is mounted at a first end of the first optical fiber. The first end of the first optical fiber is positioned within the interior of the enclosure. The first fiber optic connector is inserted within the first fiber optic adapter. The enclosure and the spool are configured to rotate in unison about a common axis when the fiber optic cable is unwound from the spool.

Claims

1-2. -2. (canceled)

3. A fiber optic enclosure assembly comprising:

an enclosure including;

a housing having a base and a plurality of sidewalls, the housing defining an interior region, the base defining a cable passage;

a cover engaged to the housing;

a plurality of adapters disposed in the interior region of the housing, the plurality of adapters having a first side and an oppositely disposed second side;

a cable spool connected to an exterior of the enclosure, the cable spool including;

a first flange having an inner diameter and an outer diameter, the first flange defining an access notch that extends from the inner diameter radially outward toward the outer diameter;

a drum portion engaged to the first flange, the drum portion being adapted to receive a fiber optic cable;

a second flange engaged to the drum portion opposite the first flange; and

a bracket disposed adjacent to the first flange, the bracket being adapted to receive the housing of the enclosure so that the cable passage in the base is aligned with access notch in the first flange.

4. The fiber optic enclosure assembly of claim 3, further comprising a mounting assembly configured for mounting to a vertical surface, the mounting assembly being rotationally engaged with the cable spool such that the cable spool and the enclosure selectively rotate about an axis of the mounting assembly.

5. The fiber optic enclosure assembly of claim 4, wherein the mounting assembly includes a first plate, a second plate and a bearing assembly disposed between the first and second plates.

6. The fiber optic enclosure assembly of claim 5, wherein the first plate is engaged to the cable spool.

7. The fiber optic enclosure assembly of claim 6, wherein the first plate includes a protrusion that is engaged in a notch defined by the drum portion of the cable spool to prevent relative rotation between the first plate and the cable spool.

8. The fiber optic enclosure assembly of claim 5, wherein the bearing assembly includes a ring member having an inner bore and a puck member disposed within the inner bore of the ring member.

9. The fiber optic enclosure as claimed in claim 8, wherein the inner bore of the ring member includes a first surface, an oppositely disposed second surface, and a bearing surface with the bearing surface being disposed at an angle from the second surface that is less than or equal to about 90 degrees.

10. A fiber optic enclosure as claimed in claim 9, wherein the puck member includes a first end surface, an oppositely disposed second end surface, and a mating bearing surface with the mating bearing surface being disposed at an angle from the second end surface that is less than or equal to about 90 degrees.

11. A fiber optic enclosure as claimed in claim 8, wherein silicon grease is disposed between the puck member and the inner bore of the ring member.

16. A fiber optic enclosure assembly comprising:

an enclosure including;

a housing having a base and a plurality of sidewalls, the housing defining an interior region, the base defining a cable passage;

a cover engaged to the housing;

a fanout disposed in the interior region;

a plurality of adapters disposed in the interior region of the housing, the plurality of adapters having a first side and an oppositely disposed second side;

a cable spool connected to an exterior of the enclosure, the cable spool including;

a first flange having an inner diameter and an outer diameter, the first flange defining an access notch that extends from the inner diameter radially outward toward the outer diameter;

a drum portion engaged to the first flange, the drum portion being adapted to receive a fiber optic cable;

a second flange engaged to the drum portion opposite the first flange;

a bracket disposed adjacent to the first flange, the bracket being adapted to receive the housing of the enclosure so that the cable passage in the base is aligned with access notch in the first flange; and

a mounting assembly configured for mounting to a vertical surface, the mounting assembly being rotationally engaged with the cable spool such that the cable spool and the enclosure selectively rotate about an axis of the mounting assembly.

17. The fiber optic enclosure assembly of claim 16, wherein the mounting assembly includes a first plate, a second plate and a bearing assembly disposed between the first and second plates.

18. The fiber optic enclosure assembly of claim 17, wherein the first plate is engaged to the cable spool.

19. The fiber optic enclosure assembly of claim 18, wherein the first plate includes a protrusion that is engaged in a notch defined by the drum portion of the cable spool to prevent relative rotation between the first plate and the cable spool.

20. The fiber optic enclosure assembly of claim 17, wherein the bearing assembly includes a ring member having an inner bore and a puck member disposed within the inner bore of the ring member.

21. The fiber optic enclosure as claimed in claim 20, wherein the inner bore of the ring member includes a first surface, an oppositely disposed second surface, and a bearing surface with the bearing surface being disposed at an angle from the second surface that is less than or equal to about 90 degrees.

22. A fiber optic enclosure as claimed in claim 21, wherein the puck member includes a first end surface, an oppositely disposed second end surface, and a mating bearing surface with the mating bearing surface being disposed at an angle from the second end surface that is less than or equal to about 90 degrees.
