INTERCONNECTING PROCESSING UNITS OF A STORED PROGRAM CONTROLLED SYSTEM USING SPACE DIVISION MULTIPLEXED FREE SPACE OPTICS

摘要

Internal communication signals in a stored program controlled system comprising a plurality of units configured to process signals are provided b y 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.
