Abstract

Fiber optic networks are considered as a viable alternative to the conventional coaxial distribution systems for Space Station. The multiple access communication subsystem provides 450-750MHz data signal on offset quadrature phase shift keying (OQPSK) format to antenna mounted electronics. For coherent communication 100MHz frequency reference signal is transmitted to each module to phase lock a dielectric resonator oscillator at 14.15GHz. Experimental results of phase locked oscillator's spectral purity, synchronized via two commercial fiber-optic links at 1.3tim and 0.8gm, are reported. These two fiber-optic links were compared in terms of phase noise degradation. Furthermore, experimental results of fiber-optic link linearity, third order intermodulation distortion, dynamic range and effect of mixing between data and the frequency reference are reported.
