Abstract

High density optical fiber distribution sub-rack comprising: a chassis for housing a plurality of shelves, the chassis comprising at least two shelf storage areas placed side by side with each other, at least one shelf housed in one of the at least two storage areas of the chassis, the at least one shelf having an internal hollow seat for connection modules, the at least one shelf comprising one or more connection modules having a plurality of adapters for interconnection optical fibers, the connection modules being arranged in the internal hollow seat of the at least one shelf at the frontal face of the at least one shelf, wherein the at least one shelf is guided so as to be movable towards the external of the chassis by the succession of a translation movement and a rotation movement of the at least one shelf.

First claim

The invention claimed is:

1. A high density optical fiber distribution sub-rack comprising:
a chassis for housing a plurality of shelves, the chassis comprising at least two shelf storage areas placed side by side with each other; and
at least one shelf housed in one of the at least two storage areas of the chassis, the at least one shelf having an internal hollow seat for connection modules, the at least one shelf comprising one or more connection modules having a plurality of adapters for interconnection optical fibers, the connection modules being arranged in the internal hollow seat of the at least one shelf at the frontal face of the at least one shelf, wherein the at least one shelf is guided so as to be movable towards the external of the chassis by the succession of a translation movement and a rotation movement of the at least one shelf, wherein the at least one shelf is guided by a guided pin that cooperates with a guiding slot, the guiding pin being fixed to the chassis inside the shelf storage areas, wherein the at least one shelf is housed and the guiding slot being made in the at least one shelf.

2. The high density optical fiber distribution sub-rack according to claim 1 , wherein the rotation movement occurs around an axis orthogonal to a bottom wall of the chassis.

3. The high density optical fiber distribution sub-rack according to claim 1 , wherein each one of the shelf storage areas houses at least one of the shelves, the guiding pins and the guiding slots of the shelves are arranged so that the rotation of two shelves housed in adjacent shelf storage areas occur in two opposite directions.

4. The high density optical fiber distribution sub-rack according to claim 1 , wherein at least one of the shelf storage areas comprises a plurality of shelves superimposed one on top of the other so that the guiding slots are aligned.

5. The high density optical fiber distribution sub-rack according to claim 1 , wherein the guiding pins present a double D cross sectional shape and the guiding slots present straight sides, circular ends and curved ends.

6. The high density optical fiber distribution sub-rack according to claim 1 , wherein the connection modules are arranged in a single array or in two stacked arrays placed side by side with each other.

7. The high density optical fiber distribution sub-rack according to claim 1 , wherein the at least one shelf is made in a single molded plastic piece.

8. A high density optical fiber distribution sub-rack comprising:
a chassis for housing a plurality of shelves, the chassis comprising a first shelf storage area and a second shelf storage area placed side by side with each other;
a first shelf housed in the first shelf storage area, the first shelf having a first internal hollow seat for first connection modules, each of the first connection modules having a plurality of first adapters for interconnection optical fibers, the first connection modules being arranged in the first internal hollow seat of the first shelf at a face of the first shelf, wherein the first shelf is guided so as to be movable towards the external of the chassis by the succession of a translation movement and a rotation movement of the first shelf; and
a second shelf housed in the second shelf storage area, the second shelf having a second internal hollow seat for second connection modules, each of the second connection modules having a plurality of second adapters for interconnection optical fibers, the second connection modules being arranged in the second internal hollow seat of the second shelf at a face of the second shelf, wherein the second shelf is guided so as to be movable towards the external of the chassis by the succession of a translation movement and a rotation movement of the second shelf, wherein the first shelf is guided by a first guided pin that cooperates with a first guiding slot, the first guiding pin being fixed to the chassis inside the first shelf storage area, wherein the first shelf is housed and the first guiding slot being made in the first shelf, and wherein the second shelf is guided by a second guided pin that cooperates with a second guiding slot, the second guiding pin being fixed to the chassis inside the second shelf storage area, wherein the second shelf is housed and the second guiding slot being made in the second shelf.

9. The high density optical fiber distribution sub-rack according to claim 8 , wherein the rotation movement occurs around an axis orthogonal to a bottom wall of the chassis.

10. The high density optical fiber distribution sub-rack according to second guiding pins and the second guiding slots of the second shelf are arranged so that the rotation of the first shelf occurs in a direction opposite to the rotation of the second shelf.

11. The high density optical fiber distribution sub-rack according to claim 8 , wherein the first shelf storage area further comprises a plurality of first shelves disposed over the first shelf and superimposed one on top of each other so that the first guiding slots are aligned and wherein the second shelf storage area further comprises a plurality of second shelves disposed over the second shelf and superimposed one on top of each other so that the second guiding slots are aligned.

12. The high density optical fiber distribution sub-rack according to claim 8 , wherein the first guiding pins have a double D cross sectional shape and the first guiding slots have straight sides, circular ends and curved ends, and wherein the second guiding pins have a double D cross sectional shape and the second guiding slots have straight sides, circular ends and curved ends.

13. The high density optical fiber distribution sub-rack according to claim 8 , wherein the first connection modules and the second connection modules are arranged in a single array.

14. The high density optical fiber distribution sub-rack according to claim 8 , wherein the first connection modules and the second connection modules are each arranged in two stacked arrays placed side by side with each other.

15. The high density optical fiber distribution sub-rack according to claim 8 , wherein the first shelf is made in a first single molded plastic piece, and wherein the second shelf is made in a second single molded plastic piece separate from the first single molded plastic piece.

16. An optical fiber distribution sub-rack comprising:
a chassis comprising shelf storage areas placed side by side with each other; and
at least one shelf housed in one of the storage areas of the chassis, the at least one shelf having an internal hollow seat, the at least one shelf comprising one or more connection modules having a plurality of adapters for interconnection optical fibers, the one or more connection modules being arranged in the internal hollow seat of the at least one shelf at the frontal face of the at least one shelf, wherein the at least one shelf is guided so as to be movable towards the external of the chassis by the succession of a translation movement and a rotation movement of the at least one shelf, wherein the rotation movement occurs around an axis orthogonal to a bottom wall of the chassis, wherein the at least one shelf is guided by a guided pin that cooperates with a guiding slot, the guiding pin being fixed to the chassis inside the shelf storage areas, wherein the at least one shelf is housed and the guiding slot being made in the at least one shelf.

17. The optical fiber distribution sub-rack according to claim 16 , wherein the connection modules are arranged in a single array or in two stacked arrays placed side
