Abstract

Optical connection verification schemes that do not cause electromagnetic interference. An all-optical connection verification scheme exploits optical coding based on a standard color scale such as RGB (red, green, blue). An RGB LED source is used to launch a three-color optical signal where the relative (or absolute) magnitudes of the color components identify the connection. On the receiver end, an RGB photodiode measures the relative (or absolute) magnitudes of the color components to verify the connection. Alternatively, one end of the connection may transmit white light with the other end reflecting back a similar three-color signal by use of a color-coded panel reflector.
