Abstract
A circuit for presenting one or more current source outputs which may be used to optimize the interface between optical components in a computer system. The multiple currents may be independently varied in each particular component to provide a current adjustment for proper functioning of a wide variety of LEDs and photo transistors. As a result, a dynamic optimization of the devices is provided. Since the present invention allows a wide variety of optical components to be used, the overall cost of implementing the device may be reduced.
