A cost effective fiber optic uplink for video information has been designed and successfully tested in a shallow water (i.e. < 20 meters) environment. The camera and transmitter are operated within a diver held underwater light housing. A novel fiber optic housing penetrator has been designed and tested down to a depth of 1200 meters. The receiver on the surface can drive a monitor or video tape recorder. As tested the system provides ample margin for much longer link distances. Quantitative information (e.g. heading or depth) can be superimposed on the video data for display. A preliminary design expanding the link to include a bidirectional capability allowing a lower frequency (control data) downlink is also discussed.
