ABSTRACT:
Internal communication signals in a stored program controlled system comprising a plurality of units configured to process signals are provided by an optical beam line which is proximal to all of the plurality of units. The system of this invention uses Space Division Multiplexing techniques to provide a plurality of logically independent subchannels over a single, shared free space optical beamline.
