Abstract

An enclosure for housing fiber optic splices between a fiber optic distribution cable and fiber optic customer drop cables includes a first door providing access to a first area of the enclosure housing couplers for receiving terminals of customer drop cables. The enclosure also includes a second door providing access to a second area of the enclosure for accommodating slices in one or more distribution cables. The second area is not accessible via the first area.

Claims (42)

1. A fiber optic cable splice enclosure comprising:

a first access door attached to said enclosure and having a closed condition and an open condition which provides access to a first area within said enclosure for housing at least one fiber optic customer drop cable;

a second access door attached to said enclosure and having a closed condition and an open condition which provides access to a second area within said enclosure for housing at least one fiber optic distribution cable, wherein said second area is manually inaccessible from said first area;

a plurality of fiber optic couplers located within said first area for receiving terminals of customer drop cables;

a splitter residing within a portion of said enclosure, said splitter including a fiber optic input and a plurality of fiber optic outputs, several of said plurality of fiber optic outputs being respectively coupled to individual couplers of said plurality of fiber optic couplers, wherein said splitter is located outside of said first area of said enclosure; and

a third area formed between said first area and said second area, wherein said third area is bordered by a first bulkhead between said first area and said third area and a second bulkhead between said second area and said third area, and wherein said splitter resides within said third area.

2. The fiber optic cable splice enclosure of claim 1 , wherein said plurality of fiber optic couplers are attached to said first bulkhead, and further comprising:

a guide track for guiding customer drop cables within said first area at bends greater than a minimum bend radius of the customer drop cables and for storing slack in the customer drop cables.

3. The fiber optic cable splice enclosure of claim 2 , wherein said plurality of fiber optic couplers receive terminals at an acute angle relative to a plane of said first bulkhead.

4. The fiber optic cable splice enclosure of claim 1 , further comprising:

a plurality of holder slots formed on or attached to said first bulkhead and facing said first area for holding one or more splice sleeves on one or more customer drop cables.

5. The fiber optic cable splice enclosure of claim 1 , further comprising:

a plurality of holder slots formed on or attached to said second bulkhead and facing said second area for holding one or more splice sleeves on one or more distribution cables.

6. The fiber optic cable splice enclosure of claim 1 , wherein said splitter is connected to said second bulkhead.

7. The fiber optic cable splice enclosure of claim 6 , wherein at least one of said first and second bulkheads is removably attached to said enclosure via fasteners and may be moved relative to said enclosure to access said splitter.

8. The fiber optic cable splice enclosure of claim 1 , wherein said first access door forms a first side of said enclosure, and wherein said second access door forms a second and opposite side of said enclosure.

9. The fiber optic cable splice enclosure of claim 8 , wherein said first access door is generally formed as a panel having one side edge connected to said enclosure by at least one hinge.

10. The fiber optic cable splice enclosure of claim 8 , wherein said first access door is generally formed as a panel which is removably mounted to said enclosure.

11. The fiber optic cable splice enclosure of claim 8 , wherein said second door includes plural through holes therein, and said enclosure includes plural threaded bosses, and wherein said plural through holes are in alignment with said plural threaded bosses when said second door is in the closed condition.

12. The fiber optic cable splice enclosure of claim 1 , further comprising:

a grounding bar or plate located within said first area provided for grounding of conductive strength members and armor of armored cables, and for tie down of dielectric strength members.

13. The fiber optic cable splice enclosure of claim 1 , wherein said enclosure includes a cable entrance and exit side for passage of one or more customer drop cables and one more distribution cables, wherein said cable entrance and exit side includes a gasket to resist moisture from entering said enclosure.

14. A fiber optic cable splice enclosure comprising:

a first access door attached to said enclosure and having a closed condition and an open condition which provides access to a first area within said enclosure for housing at least one fiber optic customer drop cable;

a second access door attached to said enclosure and having a closed condition and an open condition which provides access to a second area within said enclosure for housing at least one fiber optic distribution cable, wherein said second area is manually inaccessible from said first area;

a plurality of fiber optic couplers located within said first area for receiving terminals of customer drop cables;

a third area formed between said first area and said second area, wherein said third area is bordered by a first bulkhead between said first area and said third area and a second bulkhead between said second area and said third area;

a splitter residing within said third area, said splitter including a fiber optic input and a plurality of fiber optic outputs, several of said plurality of fiber optic outputs being respectively coupled to individual couplers of said plurality of fiber optic couplers;

a plurality of first holder slots formed in or attached to said first bulkhead and facing said first area for holding one or more splice sleeves on one or more customer drop cables; and

a plurality of second holder slots formed in or attached to said second bulkhead and facing said second area for holding one or more splice sleeves on one or more distribution cables.

15. The fiber optic cable splice enclosure of claim 14 , wherein said plurality of fiber optic couplers are attached to said first bulkhead, and further comprising:

a guide track for guiding customer drop cables within said first area at bends greater than a minimum bend radius of the customer drop cables and for storing slack in the customer drop cables.

16. The fiber optic cable splice enclosure of claim 14 , wherein said first access door forms a first side of said enclosure, and wherein said second access door forms a second and opposite side of said enclosure.

17. A fiber optic cable splice enclosure comprising:

a first access door attached to said enclosure and having a closed condition and an open condition which provides access to a first area within said enclosure for housing at least one fiber optic customer drop cable;

a second access door attached to said enclosure and having a closed condition and an open condition which provides access to a second area within said enclosure for housing at least one fiber optic distribution cable, wherein said second area is manually inaccessible from said first area, wherein said first access door forms a first side of said enclosure, and wherein said second access door forms a second and opposite side of said enclosure;

a plurality of fiber optic couplers located within said first area for receiving terminals of customer drop cables;

a splitter residing within a portion of said enclosure, said splitter including a fiber optic input and a plurality of fiber optic outputs, several of said plurality of fiber optic outputs being respectively coupled to individual couplers of said plurality of fiber optic couplers, wherein said splitter is located outside of said first area of said enclosure;

a third side of said enclosure forming a cable entrance and exit side for passage of one or more customer drop cables and one or more distribution cables; and

a third area formed between said first area and said second area, wherein said third area is bordered by a first bulkhead between said first area and said third area and a second bulkhead between said second area and said third area, and wherein said splitter resides within said third area.

18. The fiber optic cable splice enclosure of claim 17 , wherein said plurality of fiber optic couplers are attached to said first bulkhead, and further comprising:
