Abstract

An optics pack including a housing unit having multiple slots configured to accept optical modules, a stack interconnect having a connector associated with a slot of the multiple slots of the housing unit, and an optics pack connector electrically coupled to the connector of the stack interconnect.

Claims

1. A carrier pack comprising

a housing unit having multiple slots configured to accept optical modules;

a stack interconnect having a connector associated with a slot of the multiple slots of the housing unit;

a carrier pack connector electrically coupled to the connector of the stack interconnect.

2. The carrier pack of claim 1, further comprising:

a main circuit board to supply an electrical path to couple the carrier pack connector to the connector of the stack interconnect.

3. The carrier pack of claim 1, further comprising:

a main circuit board to supply an electrical path to couple the carrier pack connector to the connector of the stack interconnect and configured to convert a first signaling rate associated with an optical module that is inserted into the slot to a second signaling rate associated with a device coupled to the carrier pack connector.

4. The carrier pack of claim 3 wherein multiple optical modules, each optical module associated with one of the multiple slots of the carrier pack, share a common set of circuitry on the main circuit board.

5. The carrier pack of claim 1 wherein the stack interconnect is connected to a main circuit board.

6. The carrier pack of claim 1 wherein the stack interconnect includes a riser board and a mezzanine connector.

7. The carrier pack of claim 2 wherein the stack interconnect includes a riser board and a mezzanine connector to electrically couple the connector and the main circuit board.

8. The carrier pack of claim 6 wherein the mezzanine connector includes a male portion and a female portion.

9. The carrier pack of claim 7 wherein the mezzanine connector includes a male portion and a female portion, the male portion of the mezzanine connector attaching to the main circuit board and the female portion of the mezzanine connector attaching to the riser board.

10. The carrier pack of claim 8 wherein the riser board is removably coupled to a main circuit board.

11. The carrier pack of claim 7 wherein a female portion of the mezzanine connector attaches to the main circuit board and a male portion of the mezzanine connector attaches to the riser board such that the riser board is removably coupled to the main circuit board.

12. The carrier pack of claim 7, further comprising a second riser board and a second mezzanine connector wherein the mezzanine connector attaches the riser board to a top side of the main circuit board and the second mezzanine connector attaches the second riser board to a bottom side of the main circuit board.

13. The carrier pack of claim 7 wherein the mezzanine connectors include a plastic body and metal contacts.

15. The carrier pack of claim 2 wherein the stack interconnect includes a connection to a common set of circuitry on the main circuit board.

16. The carrier pack of claim 1, further comprising

two faceplates separated from each other by a slot in the housing.

17. The carrier pack of claim 1, further comprising

a heat sink.

18. The carrier pack of claim 17 wherein an upper part of the housing includes the heat sink.

20. The carrier pack of claim 1, further comprising

status indicators associated with operation of the module or a slot of the multiple slots of the housing unit.

21. The carrier pack of claim 20, wherein a faceplate includes the status indicators.

14. (Cancelled)

19. (Cancelled)

22. An optics pack comprising:

a carrier pack comprising

a housing unit having multiple slots adapted to receive optical modules;

a stack interconnect having a connector associated with a slot of the multiple slots of the housing unit;

a carrier pack connector electrically coupled to the connector of the stack interconnect; and

a plurality of optical modules each comprising a connector adapted to electrically couple the optical module with the connector of the stack interconnect of the carrier pack.

23. An optics pack according to claim 22 configured to convert a first signaling rate associated with an optical module that is inserted into a slot of the multiple slots of the housing unit to a second signaling rate associated with a device coupled to the carrier pack connector.

24. A system comprising:

at least one carrier pack comprising

a housing unit having multiple slots adapted to accept optical modules;

a stack interconnect having a connector associated with a slot of the multiple slots of the housing unit;

a carrier pack connector electrically coupled to the connector of the stack interconnect;

a plurality of optical modules, each optical module comprising a connector adapted to electrically couple the optical module with the connector of the stack interconnect of the at least one carrier pack; and

a switch self adapted for receiving the at least one carrier pack, the switch shelf comprising a back plane adapted to couple the switch shelf with the carrier pack connector of the at least one carrier pack.
