In this paper we present a simplified polarization division multiplexing (PDM) free space optical (FSO) communication system. The system is based on sending two different information signals on two orthogonal polarizations. Results show that a vertically polarized 632 nm light signal suffers a great deal of attenuation in a FSO channel. Results also show that it is possible to generate a polarized light for its orthogonal polarization using polarization rotation, however, the insertion loss is very high. Finally we showed that it is possible to send two different information signals on two orthogonal polarization, however, the detected signals were heavily distorted
