Claim Text:
1. An optical communications module comprising: upper and lower housing portions mechanically coupled with one another to provide a module housing; a first lead frame fixedly positioned in the module housing; at least a first light source driver circuit mounted on a first mounting surface of the first lead frame; a second lead frame fixedly positioned in the module housing and spatially separated from the first lead frame, wherein a first air flow path flows across at least a portion of the first lead frame; at least a first light source mounted on the second lead frame, wherein a second air flow path flows across at least a portion of the second lead frame, and wherein the first and second air flow paths are isolated from one another; and at least a first electrical interconnection electrically interconnecting the first light source driver circuit and the first light source, wherein the spatial separation of the first and second lead frames from one another and direct cooling of the first and second lead frames provided by the air flow paths provide a heat dissipation solution for the module; a printed circuit board (PCB) fixedly positioned in the module housing; an organic substrate mounted on the upper surface of the PCB and electrically interconnected with the PCB, and wherein the organic substrate is electrically connected to the first light source driver circuit; and at least a first integrated circuit (IC) mounted on and electrically interconnected with the organic substrate to enable communication between the first IC and the first light source driver circuit, the organic substrate mechanically coupling the first IC to the upper surface of the PCB, wherein the first air flow path also flows across the first IC and across at least a portion of the upper surface of the PCB, and wherein the second air flow path also flows across a lower surface of the PCB.
