Abstract

There is provided fiber drop terminal (“FDT”) assemblies for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDT assemblies include a mounting plate that enables the FDT to be conveniently and securely mounted to a generally vertical surface, such as a wall. The mounting plate is structured such that the base of the FDT must be removed before the mounting plate can be removed, and the cover of the FDT is structured that neither the base nor the mounting plate can be removed without first removing the cover. The cover may be selectively locked to the base and/or mounting plate with a locking fastener; therefore, only technicians able to remove the locking fastener may remove the cover, base, and/or mounting plate of the FDT assembly.

Claims

1. A mounting plate adapted for use with a fiber drop terminal (“

FDT”

), wherein the mounting plate is selectively mountable to a generally vertical surface and is adapted to selectively receive the FDT, the mounting plate comprising;

a first surface adapted to selectively engage the FDT, wherein the first surface includes at least one retention device to enable the FDT to be selectively retained by the mounting plate;

at least one fastening portion joined to the first surface, wherein the fastening portion enables the mounting plate to be selectively fastened to the generally vertical surface;

wherein the mounting plate is structured and arranged to prevent dismounting of the mounting plate without prior removal of at least a portion of the FDT from the mounting plate.

2. A mounting plate according to claim 1, wherein the first surface defines a generally vertical orientation when the mounting plate is selectively mounted to the generally vertical surface.

3. A mounting plate according to claim 1, wherein the retention device of the mounting plate comprises an aperture.

4. A mounting plate according to claim 3, wherein the aperture of the retention device comprises a first opening and a second opening contiguous thereto, and wherein the second opening is smaller than the first opening.

5. A mounting plate according to claim 1, wherein the retention device of the mounting plate comprises a lead-in portion to facilitate the selective retention of the FDT to the mounting plate.

6. A mounting plate according to claim 1, wherein the retention device of the mounting plate comprises a locking feature to enable selective locking of the FDT to the mounting plate.

7. A mounting plate according to claim 1, wherein the fastening portion comprises an opening adapted to allow passage of a fastener selectively fastened to the generally vertical surface.

8. A mounting plate according to claim 1, wherein the first surface defines a top edge and a bottom edge generally opposed thereto and defines a right side and a left side generally opposed thereto, and wherein the fastening portion comprises an opening proximate the top edge, the bottom edge, the right side, and the left side.

9. A mounting plate according to claim 1, wherein the mounting plate comprises a molded polymer material.

10. A fiber drop terminal (“

FDT”

) assembly adapted for use in a fiber optic network of a multiple dwelling unit to selectively optically connect at least one connectorized optical fiber of a distribution cable to a connectorized optical fiber of at least one drop cable, wherein the FDT assembly is adapted to be selectively mountable to a generally vertical surface, the FDT assembly comprising;

a base defining a back wall and at least one sidewall extending outwardly from the back wall, wherein the base defines at least one opening for passage of the distribution cable and the drop cable through at least one of the back wall and sidewall;

a cover adapted to selectively connect to the base;

at least one plurality of adapters joined to at least one of the base and the cover, wherein the adapters are adapted to receive a connector of the distribution cable and a connector of the drop cable to optically connect the connectorized optical fiber of the distribution cable to the connectorized optical fiber of the drop cable; and

a mounting plate that is selectively mountable to the generally vertical surface and is adapted to selectively receive the base of the FDT assembly, wherein the mounting plate is structured and arranged to prevent dismounting of the base from the mounting plate without prior disconnection of the cover from the base.

11. An FDT assembly according to claim 10 further comprising a locking fastener to selectively lock the cover to the base when the cover is selectively connected to the base.

12. An FDT assembly according to claim 10, wherein the mounting plate comprises at least one retention device to enable the base of the FDT assembly to be selectively retained by the mounting plate.

13. An FDT assembly according to claim 10, wherein the retention device of the mounting plate comprises an aperture and wherein the base of the FDT assembly comprises at least one protrusion adapted to be received by the aperture.

14. An FDT assembly according to claim 13, wherein the aperture comprises a lead-in portion to facilitate the selective receiving of the protrusion of the base by the aperture.

15. An FDT assembly according to claim 10, wherein the mounting plate comprises at least one fastening portion that enables the mounting plate to be selectively fastened to the generally vertical surface.

16. An FDT assembly according to claim 10, wherein the base comprises at least one latch device adapted to selectively retain the cover relative the base.

17. An FDT assembly according to claim 10, wherein the cover comprises at least one latch device to selectively retain the cover to the mounting plate.

18. A method of installing a fiber drop terminal (“

FDT”

) assembly to a generally vertical surface, the FDT assembly adapted for use in a fiber optic network of a multiple dwelling unit to selectively optically connect at least one connectorized optical fiber of a distribution cable to a connectorized optical fiber of at least one drop cable, the method comprising;

providing the FDT assembly comprising a base, a cover, at least one plurality of adapters joined to at least one of the base and the cover, and a mounting plate;

mounting the mounting plate to the generally vertical surface, wherein the mounting plate is selectively mountable;

retaining at least one of the base and the cover of the FDT assembly to the mounting plate, wherein the at least one of the base and the cover is selectively retained by the mounting plate; and

locking at least one of the cover and the base such that the mounting plate is prevented from selective dismounting without prior removal of at least one of the cover and the base.

19. The method of claim 18, retaining at least one of the base and the cover of the FDT assembly to the mounting plate comprises inserting a protrusion of the base into an aperture of the mounting plate.

20. The method of claim 18, wherein locking at least one of the cover and the base comprises:

inserting at least one latch device of the cover into a locking feature of the mounting plate; and

locking the cover to the base with a locking fastener.
