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.

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 beam line is configured to contain optically encoded signals, which comprises signals transmitted between and/or among the plurality of units. Each unit includes a probe for injecting optically encoded signals in the beam line and/or and for receiving optically encoded signals from the beam line. Processing units include at least one aperture for passage of the beam line. Processing units may also include a movable portion that is moved during installation of the processing unit and then replaced after the main body is in place.

Abstract: Internal communication signals in a stored program controlled system comprising a plurality of units configured to process signals are provided by a free space optical beam line which is proximal to all of the plurality of units. The free space beam line is configured to contain optically encoded signals which comprises signals transmitted between and/or among the plurality of units. Each unit includes a probe for injecting optically encoded signals in the free space beam line and/or and for receiving optically encoded signals from the free space beam line. Advantageously, there may be a first terminal at a first end of the beam line to configure to transmit and terminate the optically encoded signals and a second terminal unit at the second end of the free space beam line configured to transmit and terminate the optically encoded signals.

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 Time Division Multiplexing techniques to provide a plurality of logically independent subchannels over a single shared free space optical beam line. The single logical beam is divided temporally among the subchannels, with each subchannel operating for a selected timeslot or timeslots.
