Abstract : The patent application concerns a fiber optic data transmission apparatus using a modulated hybrid transmitter to transfer data with complete electrical isolation to a remote data reception and utilization center. A specific problem which has been encountered is the testing of weapon systems that are susceptible to radio frequency jamming. The testing of such systems requires that the system be situated in a radio frequency controlled environment with no metallic wire or similar such paths linking the outside monitoring area with the interior of the chamber. The present invention uses a fiberglass transmission medium to link the monitored points of the weapon system within the chamber to the external monitoring station.
