ABSTRACT:
A wavelength Division Multiple Access (WDMA) free space broadcast technique for optical backplanes and interplanar communications for providing free space optical interconnects between multiple circuit cards in a computer system or networking device which is compatible with existing electrical backplanes. Current equipment can easily be upgraded in the field to take advantage of this new approach by simply replacing existing printed circuit boards, without requiring a complete redesign of the copper backplane.
