Abstract

An optic module cage assembly configured to selectively receive and retain an optic module, including: an optic module cage body configured to selectively receive and retain the optic module; a stationary heatsink fixedly attached to a side of the optic module cage body; one or more spring members disposed opposite the stationary heatsink and configured to bias the optic module towards the stationary heatsink; and a floating connector disposed partially within the optic module cage body and configured to make an electrical connection with the optic module, wherein the floating connector is configured to move in a constrained manner with respect to the optic module cage body. Optionally, the optic module cage assembly also includes a floating heatsink coupled to the one or more spring members. Optionally, the optic module cage assembly further includes a heat pipe that is thermally coupled to the stationary heatsink.

First claim

What is claimed is:

1. An optic module cage assembly configured to selectively receive and retain an optic module, comprising:
an optic module cage body configured to selectively receive and retain the optic module;
a stationary heatsink fixedly attached to a side of the optic module cage body;
one or more spring members disposed opposite the stationary heatsink and configured to bias the optic module towards the stationary heatsink when the optic module is selectively inserted into the optic module cage body; and
a floating connector disposed partially within the optic module cage body and configured to make an electrical connection with the optic module when the optic module is selectively inserted into the optic module cage body, wherein the floating connector is configured to move in a constrained manner with respect to the optic module cage body.

2. The optic module cage assembly of claim 1 , wherein the stationary heatsink comprises a protruding portion that protrudes through the side of the optic module cage body and makes direct physical contact with the optic module when the optic module is selectively inserted into the optic module cage body and biased towards the stationary heatsink.

3. The optic module cage assembly of claim 1 , further comprising a floating heatsink coupled to the one or more spring members.

4. The optic module cage assembly of claim 3 , wherein the floating heatsink comprises a protruding portion that protrudes through another side of the optic module cage body and makes direct physical contact with the optic module when the optic module is selectively inserted into the optic module cage body.

5. The optic module cage assembly of claim 1 , further comprising a heat pipe that is thermally coupled to the stationary heatsink.

6. The optic module cage assembly of claim 5 , further comprising a plurality of heatsink fins that are thermally coupled to the heat pipe.

7. The optic module cage assembly of claim 1 , further comprising a fan that is thermally coupled to the stationary heatsink.

8. The optic module cage assembly of claim 1 , further comprising a thermoelectric cooler that is thermally coupled to the stationary heatsink.

9. An optic module cage assembly configured to selectively receive and retain a plurality of optic modules, comprising:
an optic module cage body configured to selectively receive and retain the plurality of optic modules;
a stationary heatsink fixedly attached to a side of the optic module cage body;
one or more spring members disposed opposite the stationary heatsink and configured to bias the optic modules towards the stationary heatsink when the optic modules are selectively inserted into the optic module cage body; and
a plurality of floating connectors disposed partially within the optic module cage body and configured to make electrical connections with the optic modules when the optic modules are selectively inserted into the optic module cage body, wherein the floating connectors are each configured to move in a constrained manner with respect to the optic module cage body.

10. The optic module cage assembly of claim 9 , wherein the stationary heatsink comprises a protruding portion that protrudes through the side of the optic module cage body and makes direct physical contact with the optic modules when the optic modules are selectively inserted into the optic module cage body and biased towards the stationary heatsink.

11. The optic module cage assembly of claim 9 , further comprising one or more floating heatsinks coupled to the one or more spring members.

12. The optic module cage assembly of claim 11 , wherein the floating heatsinks each comprise a protruding portion that protrudes through another side of the optic module cage body and makes direct physical contact with an associated optic module when the optic module is selectively inserted into the optic module cage body.

13. The optic module cage assembly of claim 9 , further comprising a heat pipe that is thermally coupled to the stationary heatsink.

14. The optic module cage assembly of claim 13 , further comprising a plurality of heatsink fins that are thermally coupled to the heat pipe.

15. The optic module cage assembly of claim 9 , further comprising one or more of a fan that is thermally coupled to the stationary heatsink and a thermoelectric cooler that is thermally coupled to the stationary heatsink.

16. An optic module cage assembly configured to selectively receive and retain an optic module, comprising:
an optic module cage body coupled to a faceplate of an optic shelf or rack and configured to selectively receive and retain the optic module;
a stationary heatsink fixedly attached to a side of the optic module cage body;
one or more spring members disposed opposite the stationary heatsink and configured to bias the optic module towards the stationary heatsink when the optic module is selectively inserted into the optic module cage body; and
a floating connector coupled to a printed circuit board, disposed partially within the optic module cage body, and configured to make an electrical connection with the optic module when the optic module is selectively inserted into the optic module cage body, wherein the floating connector is configured to move in a constrained manner with respect to the optic module cage body;
wherein the optic module cage body is not fixedly secured to the printed circuit board.

17. The optic module cage assembly of claim 16 , wherein the stationary heatsink comprises a protruding portion that protrudes through the side of the optic module cage body and makes direct physical contact with the optic module when the optic module is selectively inserted into the optic module cage body and biased towards the stationary heatsink.

18. The optic module cage assembly of claim 16 , further comprising a floating heatsink coupled to the one or more spring members.

19. The optic module cage assembly of claim 18 , wherein the floating heatsink comprises a protruding portion that protrudes through another side of the optic module cage body and makes direct physical contact with the optic module when the optic module is selectively inserted into the optic module cage body.

20. The optic module cage assembly of claim 16 , further comprising one or more of a heat pipe that is thermally coupled to the stationary heatsink and a plurality of heatsink fins that are thermally coupled to the heat pipe.
