Abstract

In this paper a controlled lab chamber is used to simulate the outdoor free space optical (FSO) communication channel under moderate turbulence regime. The turbulence was generated by using high temperature gradients as well as blowing wind parallel along the optical path of ~ 7.1 m. A modulated laser beam using on-off keying (OOK) signaling scheme propagated through this simulated turbulence chamber and the received signal was analysed in order to study the performance of FSO link under moderate turbulence regime. The experimental setup has been discussed in details. The results of the eye diagrams and quality-factor (Q-factor) of the received signals are presented. The results show the accuracy of chamber which is used to characterize the moderate turbulence regime.
