Abstract

Satellite receiving terminals can benefit by locating the antennas on hill tops or away from interference and locating the receivers at a convenient, more accessible location. Wideband, high dynamic range, analog fiber optic links can replace conventional coax, wave-guide or microwave link techniques by using signal converters that offer superior performance, plus operational convenience and flexibility. This paper discusses a five mile ground link using single mode fiber and direct modulated DFB lasers. Complete C-band links have been built that achieve over 114 dB/Hz^(2/3) dynamic range and a low total group delay of less than 1 nsec p-p. Both the completed transmitter and receiver fit in 2 unit high 19 inch rack mount assemblies, use less than 12.5 watts total dc power, and the completed link MTBF was greater than 70,000 hours.
