Abstract: Intertwined TROSA Heatsink Fin Adapter for High Power TROSA Heatsink for Bidirectional Coherent Optics for Outdoor Conduction Cooled System A transmit- receive optical sub-assembly (TROSA) fin adapter assembly that effectively thermally couples the heatsink fins and plug body of a plug with a cold plate or chassis heatsink. The TROSA fin adapter assembly includes an adapter body that is disposed above and around the heatsink fins of the plug and a plurality of adapter fins that are disposed between and intertwined with the heatsink fins of the plug. Optionally, the TROSA fin adapter assembly includes adapter sides that are also disposed adjacent to the sides of the plug body. Thus, the TROSA fin adapter provides a conformal thermal interface between the heatsink fins and plug body of the plug and the cold plate or chassis heatsink. The result is the TROSA of the high power optics of the BiDi coherent plug of an air cooled conduction system, such as an outdoor system, being adequately cooled under most ambient conditions.
