Experimental study on 10Gbit/s free-space optical transmission system

摘要

Free-space optical (FSO) communication has attracted considerable attention in recent years due to it's widely applications as an alternative to fiber transmission and radio frequency communication system. In this paper an experiment on 10Gbit/s free-space optical communication channel transmission over 37m was demonstrated and the system performance was evaluated according to the bit error rate (BER) curve. Using the phase-screen method and Kolmogorov spectrum, in addition the impact on signal in free-space communication due to atmospheric turbulence was studied in detail.
