Abstract

This paper reports the result of follow-on study about the propagation characteristics of direct single mode fiber (SMF) coupled free-space optical (FSO) signals which have been obtained during recent outdoor propagation experiments over 100-500 m link distance. We observed good agreements of the surge height distribution of SMF-coupled optical signal intensity with those of the lognormal prediction. However, the same comparison for the fade depth of SMF-coupled signal indicated 2-3 times larger results. These statistical analyses have validated the method used in this paper to compare atmospheric turbulence model with real experimental data and predict the SMF-coupled signal quality based on the scintillation index determined by C_n² profiles.
