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.
Claims19
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.
1 more element
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 with a gap sufficient for permitting entrance of the fins on the pluggable module, and to remain rotated while the pluggable module remains inserted, wherein the rotating door is further configured to provide airflow upon receiving fins on the pluggable module.
