A sensing system including an optical receiver for receiving downstream optical signals and for converting the downstream optical signals to downstream electrical signals. An optical transducer impresses information in an upstream data signal onto upstream optical signals. At least one sensor responsive to an external stimulus provides sensor information signals. A processor receives the downstream electrical signals and establishes communication channels to at least one communication terminal providing communication information signals, and to the at least one sensor. The at least one terminal and the at least one sensor provide the communication and sensor information signals, respectively, to the processor which forwards the information signals to the optical transducer as the upstream data signal.
