Abstract
A thermal interface structure for electronic devices, such as telecommunications or data networking hardware, that utilize optical transceiver modules which are inserted within cage receptacles of the electronic devices. In order to provide for efficient heat transfer, the thermal interface structure is disposed between, and in abutment with, the optical transceiver module and a heat sink associated with the cage receptacle. The thermal interface structure includes a thermal interface layer including a phase change material, and a polymer layer connected to the thermal interface layer.
