A thermal chassis includes thermal collection, transfer and distribution members that collect the repeater modules' waste heat through respective thermal interfaces, transfer the waste heat along respective thermal conduction paths to the environmental enclosure, and then distribute the waste heat over a substantial portion of the enclosure's available surface area to form an enlarged thermal interface for convectively transferring the waste heat to the ambient air. Heat transfer is further improved by expanding the enclosure's external surface area and fabricating the distribution members so that they are in permanent and intimate thermal contact with the enclosure's expanded surface area.
