Abstract:
1. A transceiver module comprising: a leadframe having a plurality of die attach regions that form portions of a heat spreader device of the leadframe, the leadframe having at least a first slot formed therein to provide an air gap between at least first and second die attach regions of said plurality of die attach regions; a transceiver module housing secured to the leadframe, the transceiver module having a connector module alignment mechanism and a connector module locking mechanism, the connector module alignment mechanism being configured to engage an alignment mechanism of a connector module to align the connector module with the transceiver module, the connector module locking mechanism being configured to engage the connector module to secure the connector module to the transceiver module; an optics system of the transceiver module secured to the transceiver module housing, the optics system having a housing that houses one or more optical elements of the optics system; a circuit board comprising a plurality of conductors; a controller circuit secured to one of said plurality of die attach regions of the leadframe and having one or more electrical contacts that are electrically coupled to one or more of the conductors of the circuit board; a laser diode driver circuit secured to said first die attach region of the leadframe and having one or more electrical contacts that are electrically coupled to one or more of the conductors of the circuit board; and a laser diode circuit secured to said second die attach region of the leadframe and having one or more electrical contacts that are electrically coupled to one or more of the electrical contacts of the laser diode driver circuit, the laser diode circuit comprising said one or more laser diodes of the transceiver module, wherein said first slot formed in the leadframe at least partially thermally isolates the laser diode circuit from the laser diode driver circuit.
