Patent ID: 8358504

Claim:
An electrical system, the electrical system comprising: a transceiver module with a housing, the housing containing a plurality of apertures to allow air flow into and out of the transceiver module; an internal heat sink located within the housing of the transceiver module, the internal heat sink thermally coupled to at least one internal component of the transceiver module; and a cage for receiving and electrically connecting to the transceiver module, the cage including a second set of apertures; wherein when the transceiver module is inserted into the cage, air may flow into the cage through the second set of apertures, then flow into the transceiver module through one of the plurality of apertures in the housing such that the air dissipates heat from the at least one internal component thermally coupled to the internal heat sink, and then the air may flow out of the transceiver through another of the plurality of apertures in the housing.
