ABSTRACT:
The present invention is an optoelectronic device including a circuit board with a plurality of signal traces, a first ground plane, and a second ground plane. The impedance of a signal trace is determined by which of the first ground plane and the second ground plane is closest to the signal trace. The area of the first ground plane coincident with a first signal trace is left intact in order to set the impedance of the first signal trace, by reference to the first ground plane. The area of the first ground plane coincident with a second signal trace is removed in order to set the impedance of the second signal trace, by reference to the second ground plane.
