Abstract

A fiber panel system includes a chassis and at least a first blade configured to moveably mount to the chassis. Each blade includes a base, a frame, and front couplers. The base of each blade defines at least one opening at a location spaced rearwardly from the front couplers. The front couplers may be smart or passive.

Claims

1. A bladed chassis system comprising:

a chassis including a base, a first sidewall, and a second sidewall that cooperate to define an interior, the first sidewall defining an aperture therethrough; and

a blade configured to be disposed within the interior of the chassis, the blade including;

a base having a depth that extends between a front and a rear of the base, and a width that extends between a first side and an opposite second side of the base, the base including a planar surface that extends along a majority of the depth of the base;

a first pair of resilient arms disposed at the first side of the base, each of the resilient arms of the first pair having a distal end defining a first latching member, each first latching member being movable towards the base as the respective first resilient arm flexes towards the base along a length of the respective first resilient arm;

a second pair of resilient arms disposed at the second side of the base, each of the resilient arms of the second pair having a distal end defining a second latching member, each second latching member being movable towards the base as the respective second resilient arm flexes towards the base along a length of the respective second resilient arm;

a frame coupled to the front of the planar surface of the base, the frame having a front face extending generally perpendicular to the planar surface of the base, the front face defining a plurality of openings; and

a plurality of front couplers positioned in the openings of the frame, the front couplers defining a plurality of front-facing ports and a plurality of rear-facing ports;

wherein the planar surface of the base defines at least one through-opening at a location spaced rearwardly from the front couplers, the through-opening in the planar surface of the base providing finger access to the rear-facing ports of the front couplers; and

wherein one of the first latching members is accessible through the aperture from an exterior of the chassis when the blade is disposed in a first position and wherein another of the first latching members is accessible through the aperture from the exterior of the chassis when the blade is disposed in a second position.

2. The blade of claim 1, wherein the front couplers are separated into a first group located towards the first side of the base and a second group location towards the second side of the base.

3. The blade of claim 2, wherein the through-opening defined in the base extends across the first group of front couplers and wherein the base also defines a second through-opening extending across the second group of front couplers.

4. The blade of claim 2, wherein the first group is spaced from the second group.

5. The blade of claim 4, wherein the frame defines a reduced height section extending between the first and second groups of front couplers.

6. The blade of claim 2, wherein each group of front couplers includes six front couplers.

7. The blade of claim 2, wherein each front coupler defines four front-facing ports.

8. The blade of claim 2, wherein each group of front couplers defines twenty-four front-facing ports.

9. The blade of claim 2, wherein each group of front couplers includes eight front couplers.

10. The blade of claim 2, wherein each group of front couplers defines eight front-facing ports.

11. The blade of claim 2, wherein each group of front couplers is separated into first and second subgroups, the second subgroup being spaced from the first subgroup.

12. The blade of claim 1, wherein the plurality of front couplers includes sixteen front couplers.

13. The blade of claim 12, wherein each front coupler is configured to receive an MPO-type optical connector.

14. The blade of claim 1, wherein the plurality of front couplers includes twelve front couplers.

15. The blade of claim 14, wherein each front coupler is configured to receive an LC-type optical connector.

16. The blade of claim 14, wherein each front coupler is configured to receive an SC-type optical connector.

17. The blade of claim 1, wherein each front coupler is positioned in a separate one of the openings of the frame.

18. The blade of claim 1, wherein multiple front couplers are positioned in each of the openings of the frame.

19. The blade of claim 18, wherein each opening in the frame holds three front couplers.

20. The blade of claim 1, wherein a plurality of flanges extend rearwardly from the base.

21. The blade of claim 20, wherein the flanges include two outer flanges and two inner flanges.

22. The blade of claim 21, wherein cable tie locations are provided at distal ends of the inner flanges.

23. The blade of claim 1, further comprising a plurality of rear couplers coupled to the rear of the base.

24. The blade of claim 23, wherein the rear couplers are configured to receive MPO-type optical connectors.

25. The blade of claim 1, further comprising a plurality of retention fingers extending forwardly of the front couplers.

26. The blade of claim 25, wherein the retention fingers are coupled to the front face of the frame.

27. The blade of claim 1, further comprising a plurality of outgoing media segments having connectorized ends plugged into a plurality of the front-facing ports of the blade.

28. The blade of claim 27, further comprising a plurality of incoming media segments having connectorized ends plugged into the rear-facing ports of the front couplers, the front couplers optically coupling the incoming media segments to the outgoing media segments.

29. The blade of claim 27, further comprising:

a plurality of incoming media segments having connectorized ends plugged into rear ports of a plurality of rear couplers positioned at the rear of the base; and

a plurality of connecting media segments extending between front ports of the rear couplers and the rear-facing ports of the front couplers, the connecting media segments optically coupling the incoming media segments to the outgoing media segments.

30. The blade of claim 1, further comprising a handle extending from the base.

31. The blade of claim 1, wherein each front coupler includes at least one media reading interface.

32. The blade of claim 31, further comprising a blade processor configured to manage the media reading interfaces of the front couplers.

33. The blade of claim 32, further comprising a circuit board arrangement that electrically couples the blade processor and the media reading interfaces, the circuit board arrangement defining a connection edge for connection to a master processor via a backplane.
