Abstract

A fiber panel system includes a chassis and at least blades configured to mount to the chassis. Each blade is moveable relative to the chassis between a retracted (closed) position and at least one extended position. Cable slack is managed at the front and/or rear of each chassis to facilitate movement of the blades without pulling or bending the cables beyond a maximum bend limit. Each blade may be locked into one or more positions relative to the chassis.

First claim

The invention claimed is:

1. A fiber optic blade for use in a bladed chassis panel, the fiber optic blade comprising:
a blade body including a flat panel extending between a front and a rear and between a first side and a second side;
a front circuit board disposed at the front of the blade body;
a rear circuit board disposed at the rear of the blade body, the rear circuit board being spaced from and electrically connected to the front circuit board;
a pair of inner flanges extending rearwardly of the blade body from opposite sides of the rear circuit board;
a pair of outer flanges extending rearwardly of the blade body at the first and second sides of the blade body;
a plurality of front ports disposed at the front of the blade body;
a plurality of media reading interfaces disposed at the front ports;
a processor electrically coupled to the media reading interfaces and to the front circuit board;
a first pair of latching stop members disposed at the first side of the blade body, each of the latching stop members of the first pair being biased outwardly from the first side of the blade body, and each of the latching stop members of the first pair being configured to separately displace inwardly towards the blade body; and
a second pair of latching stop members disposed at the second side of the blade body, each of the latching stop members of the second pair being biased outwardly from the second side of the blade body, and each of the latching stop members of the second pair being configured to separately displace inwardly towards the blade body.

2. The fiber optic blade of claim 1 , wherein the plurality of front ports includes a first plurality of front ports and a second plurality of front ports, the first plurality of front ports being spaced closer to the first side of the blade body than the second plurality of front ports.

3. The fiber optic blade of claim 2 , wherein the front ports of the first plurality are laterally aligned.

4. The fiber optic blade of claim 2 , wherein the front ports of the first plurality are laterally aligned with the front ports of the second plurality.

5. The fiber optic blade of claim 1 , wherein the front ports are defined by optical adapters defining slots in which the media reading interfaces are disposed.

6. The fiber optic blade of claim 5 , wherein the optical adapters are mounted to the front circuit board.

7. The fiber optic blade of claim 5 , wherein at least some of the optical adapters are sandwiched between the front circuit board and a second circuit board that is electrically connected to the front circuit board.

8. The fiber optic blade of claim 1 , wherein the blade body defines an aperture disposed at an intermediate position between the front and rear of the blade body, the aperture being elongated along an axis extending between the first and second sides of the blade body.

9. The fiber optic blade of claim 1 , further comprising:
a frame disposed at the front of the blade body, the frame holding a plurality of optical adapters that define the front ports; and
a plurality of retention fingers that mount to and extend forwardly of the frame.

10. The fiber optic blade of claim 9 , wherein the retention fingers are configured to support label panels.

11. A fiber optic blade for use in a bladed chassis panel, the fiber optic blade comprising:
a blade body including a flat panel extending between a front and a rear and between a first side and a second side; a rear circuit board disposed at the rear of the blade body; a front circuit board disposed at the front of the blade body, the front circuit board being spaced from and electrically connected to the rear circuit board a second circuit board disposed above the front circuit board at the front of the blade body, the second circuit board being electrically connected to the front circuit board; an optical adapter disposed at the front of the blade body between the front circuit board and the second circuit board;
a media reading interface disposed at the optical adapter, the media reading interface being electrically connected to the front circuit board through the second circuit board; and a processor electrically coupled to the media reading interface and to the front circuit board; and a third circuit board disposed above the front circuit board at the front of the blade body, the third circuit board being electrically connected to the front circuit board; a second optical adapter disposed at the front of the blade body between the front circuit board and the third circuit board.

12. The fiber optic blade of claim 11 , further comprising:
a first pair of latching stop members disposed at the first side of the blade body, each of the latching stop members of the first pair being biased outwardly from the first side of the blade body, and each of the latching stop members of the first pair being configured to separately displace inwardly towards the blade body; and
a second pair of latching stop members disposed at the second side of the blade body, each of the latching stop members of the second pair being biased outwardly from the second side of the blade body, and each of the latching stop members of the second pair being configured to separately displace inwardly towards the blade body.

13. The fiber optic blade of claim 11 , further comprising:
a pair of inner flanges extending rearwardly of the blade body from opposite sides of the rear circuit board; and
a pair of outer flanges extending rearwardly of the blade body at the first and second sides of the blade body.

14. The fiber optic blade of claim 11 , wherein the optical adapter is one of a plurality of optical adapters disposed between the front circuit board and the second circuit board, each of the optical adapters including a media reading interface that is electrically connected to the second circuit board.

15. The fiber optic blade of claim 11 , further comprising: a second media reading interface disposed at the second optical adapter, the second media reading interface being electrically connected to the front circuit board through the third circuit board.

16. The fiber optic blade of claim 15 , wherein the second optical adapter is one of a plurality of additional optical adapters disposed between the front circuit board and the third circuit board, each of the additional optical adapters including a respective media reading interface that is electrically connected to the third circuit board.

17. The fiber optic blade of claim 11 , wherein the blade body defines an aperture disposed at an intermediate position between the front and rear of the blade body, the aperture being elongated along an axis extending between the first and second sides of the blade body.

18. The fiber optic blade of claim 11 , further comprising:
a frame disposed at the front of the blade body, the frame holding the optical adapter; and
a plurality of retention fingers that mount to and extend forwardly of the frame.

19. The fiber optic blade of claim 18 , wherein the retention fingers are configured to support label panels.

20. A fiber optic blade for use in a bladed chassis panel, the fiber optic blade comprising:
a blade body including a flat panel extending between a front and a rear and between a first side and a second side; a circuit board arrangement mounted to the blade body, the circuit board arrangement including a front circuit board spaced from and electrically connected to a rear circuit board; a pair of inner flanges extending rearwardly of th
