Patent ID: 6873800

Claim:
A fiber optic module-comprising: a first printed circuit board having a first contact and a second contact near an edge and a first via, the second contact coupled to the first via; a first light transducer coupled to the first printed circuit board and electrically connected to the first contact; a second printed circuit board, vertically stacked and parallel to the first printed circuit board, having a second via aligned with the first via in the first printed circuit board; an interconnect coupled to the first via of the first printed circuit board at one end and the second via of the second printed circuit board at an opposite end, the interconnect to couple signals between the first printed circuit board and the second printed circuit board; a second light transducer coupled to the second printed circuit board and electrically connected to the second contact; and an electrical connector formed on an edge said first printed circuit board for plugging into a mating connector on a system circuit board, whereby a first pin on said electrical connector is electrically connected to said first light transducer, via said first printed circuit board, and a second pin on said electrical connector is electrically connected to said second light transducer, via the second printed circuit board, the interconnect and the first printed circuit board; wherein the second light transducer has an optical axis parallel to an optical axis of the first light transducer; and wherein the optical axes of the first and second light transducers define a plane, which is parallel to the first and second printed circuit boards.
