ABSTRACT:
Briefly, in accordance with one or more embodiments, a backplane includes one or more optical links and is capable of receiving one or more circuit cards. Optical signals sent via the optical links may at least partially travel in a free space region between optical elements of the circuit cards and the optical links. Optical signals may also traverse the free space between optical links in the absence of a circuit card wherein the optical signal may travel to one or more other circuit cards on the backplane. As a result, in one or more embodiments a network between one or more of the circuit cards on the backplane may be automatically configured even in the absence of one or more circuit cards from the backplane.
