Abstract
In one embodiment, an apparatus includes an optical module, and a heat sink for attachment to an optical module cage configured for receiving the optical module, the heat sink having a surface in which recesses are formed. The optical module includes a thermal interface material attached to a surface of the optical module for thermal contact with the heat sink, and lifting elements extending from the surface. The lifting elements are configured to create a gap between the thermal interface material and the heat sink during insertion of the optical module into the optical module cage or removal of the optical module from the optical module cage, and are positioned for insertion into aligned recesses in the heat sink when the optical module is fully inserted into the optical module cage to eliminate the gap and provide contact between the heat sink and the thermal interface material.
