Abstract: Presented herein are optical module cage designs and heatsink configurations for improved air cooling of pluggable optical modules disposed within the optical module cages. The designs and configurations presented herein facilitate efficient air cooling of higher power pluggable optical modules by enhancing airflow through the optical module cages, increasing contact between the optical modules and the heatsinks, and/or increasing the heatsink dissipation surface area.

Abstract: An apparatus is provided in one example embodiment and includes a faceplate having a plurality of slots arranged on a front portion of the faceplate, a top plate attached to a top portion of the faceplate, and a screen attached to the faceplate and the top plate. A channel may be disposed behind the faceplate and between a bottom surface of the top portion of the faceplate, a bottom surface of the top plate and a top surface of the screen. The screen may include a plurality of openings. In a specific embodiment, the apparatus may be removably attached to a removable line card of a switch. In a specific embodiment, air may be guided through the slots, by a fan operating behind the apparatus, along the channel and through the plurality of openings to one or more heat generating components on the line card.
