Abstract

A telecommunications device includes a module that mounts within an interior of a housing. The housing has a door that latches closed. The module includes a module frame having a bulkhead that divides the interior of the housing into first and second regions. Fiber optic adapters are mounted to the bulkhead. First ports of the adapters are accessible at the first region of the housing interior and second ports are accessible at the second region of the housing interior. The module includes a removable cover for restricting access to the first region. The removable cover including a latch catch that interlocks with the door latch to secure the door in the closed position. The module includes a tray mounted to the module frame within the first region of the housing.

First claim

What is claimed is:

1. A telecommunications device comprising:
a housing having a door for accessing an interior of the housing, the door being movable between an open position and a closed position, the door including a door latch for securing the door in the closed position; and
a module that mounts within the interior of the housing, the module including a module frame having a bulkhead that divides the interior of the housing into first and second regions, the module including a plurality of fiber optic adapters mounted to the bulkhead, the fiber optic adapters including first ports accessible at the first region of the housing interior and second ports accessible at the second region of the housing interior, the module including a removable cover mountable to the module frame for restricting access to the first region, the removable cover including a latch catch that interlocks with the door latch to secure the door in the closed position, the module including a tray mounted to the module frame within the first region of the housing.

2. The telecommunications device of claim 1 , wherein the housing includes a main housing body having an open front, a rear housing base, opposite first and second housing side walls projecting forwardly from the rear housing base, and opposite first and second housing end walls projecting forwardly from the rear housing base that extend between the opposite first and second housing side walls, and wherein the door is pivotally attached to the housing adjacent the open front by at least one hinge.

3. The telecommunications device of claim 2 , wherein the bulkhead includes first and second side tabs that attach respectively to the first and second housing side walls.

4. The telecommunications device of claim 1 , wherein the bulkhead defines at least one notch for passing a cable there-through.

5. The telecommunications device of claim 2 , wherein the first end wall corresponds to the first region of the interior of the housing and the second end wall corresponds to the second region of the interior of the housing, and wherein the second end wall defines a plurality of sealed cable access openings having open ends at the front of the main housing body for allowing cables to be inserted within the cable access openings when the door is in the open position, and wherein the door blocks the open ends of the cable access openings when the door is in the closed position.

6. The telecommunications device of claim 2 , wherein the module frame includes a module rear base having first and second opposite module ends, wherein a module end wall projects forwardly from the module rear base at the first module end, wherein the bulkhead projects forwardly from the rear base at the second module end, wherein a front flange projects from a forward end of the module end wall, wherein a cover catch is provided on the front flange, wherein the removable cover includes a cover latch that engages with the cover catch, and wherein the removable cover includes tabs that are received within slots defined by the bulkhead.

7. The telecommunications device of claim 6 , wherein the bulkhead includes first and second side tabs that are respectively fastened to the first and second housing side walls at intermediate locations between the first and second housing end walls, and wherein the module end wall is fastened to the first housing end wall.

8. The telecommunications device of claim 1 , further comprising at least one bracket for attaching the housing to a frame.

9. The telecommunications device of claim 1 , wherein the tray includes a front side for holding optical components and a rear side defining a cable pathway about which a cable can be routed to provide strain relief, and wherein the front side of the tray defines one or more fiber routing paths that define fiber storage loops.

10. The telecommunications device of claim 1 , wherein the housing is environmentally sealed.

11. The telecommunications device of claim 6 , wherein the module frame includes posts that project forwardly from the module rear base, wherein the tray includes receptacles that receive the posts, and wherein fasteners engaging the posts are used to secure the tray to the posts.

12. The telecommunications device of claim 1 , wherein a wavelength division multiplexer is positioned in the first region of the housing interior, wherein a first output of the wavelength division multiplexer is coupled to an input side of a passive optical power splitter provided at a front side of the tray, and wherein connectorized outputs of the passive optical power splitter are plugged into the first ports of the fiber optic adapters.

13. The telecommunications device of claim 12 , wherein a second output of the wavelength division multiplexer is routed out of the housing.

14. The telecommunications device of claim 13 , wherein the second output is routed about a cable pathway provided at a rear side of the tray to provide strain relief.

15. The telecommunications device of claim 14 , wherein the second output is routed from the rear side of the tray, through a notch defined by the bulkhead to the second region of the housing interior, and out of the housing through a sealed cable access opening defined at the second region of the housing interior.

16. The telecommunications device of claim 12 , wherein the housing defines a plurality of sealed cable access openings at the second region of the housing interior for allowing cables to be routed in or out of the housing, wherein the door blocks open ends of the cable access openings when the door is in the closed position.
