The system consists of a transmitting terminal and a receiving terminal which provide a simplex 5 Mbitsec data channel over a 5-mile terrestrial path with an error rate of 10 to the minus 6th power in all except the most severe weather conditions. The system utilizes intracavity electro-optic modulation with a frequency shift keying format and optical FM heterodyne detection using a mercury-cadmium-telluride HgCdTe detector operating at 77K. The details of the system design and performance over a nominal 5-mile path and a 20-mile path are given. Author
