Abstract
In one embodiment, a pluggable module has fins along a length of its shell, and a planar gap on its shell in front of the fins. The fins may rise higher than an industry-standard pluggable module. The planar gap provides for a pressure drop as air reaches the fins, and thereby improves air flow. The pluggable module plugs into a port of a cage. A key pattern or rotating door on the port is configured to allow the pluggable module's fins to pass through, while also placing a height limit on non-fin regions of the shell.
Claims20
A pluggable module comprising:
- a back-end portion with a wire-receiving opening;
- a shell portion extending from the back-end portion to a front-end portion, the front-end portion having a contact-exposing opening, the shell portion having a plurality of sides;
- and
- a plurality of fins on at least one side of the shell portion, the fins extending along a length of the shell portion from a start position toward the front-end portion, wherein a non-fin gap is defined on the at least one side of the shell portion between the back-end portion and the start position of the fins, wherein the non-fin gap is a substantially planar surface, wherein the non-fin gap is parallel to the extension direction of the shell portion, and wherein the non-fin gap separates the back-end portion from the start position of the fins.

(canceled)
A module cage comprising:
- a module-receiving opening having a key pattern configured to maintain a separation gap sufficient for permitting entrance of fins on a pluggable module into the module-receiving opening, wherein the key pattern is further configured to provide airflow upon receiving fins on the pluggable module.
A module cage comprising:
- a module-receiving opening configured to receive a pluggable module with fins;
- wherein the module-receiving opening has a rotating door configured to be rotated toward an interior of the module cage by the fins as the pluggable module is inserted into the module-receiving opening, and to remain rotated while the pluggable module remains inserted.
