N2 - This study presents and investigates a free space optics (FSO) transmission technique that utilizes polarization division multiplexing (PDM) and orbital angular momentum (OAM) multiplexing. The aim is to provide an effective and reliable backhauling solution. The transmission system uses four-level-pulse amplitude modulation (PAM-4) signals achieving a high capacity of 400 Gbps. Two orthogonal polarized beams of 1550 nm Laser diode are used. For each polarized beam, 4 OAM beams are further generated, and each OAM beam transports 50 Gbps data using PAM-4 modulation over the free space channel. The impact of varying FSO ranges on the system performance under clear weather sky (sunny), light rain (LR), medium rain (MR), and heavy rain (HR) is considered. The bit error rate (BER) metric is used to evaluate the proposed system's performance. Results from the simulation indicate that transmission of 400 Gbps is achieved successfully with a range of 1800 m, 900 m, 775 m, and 537 m under clear weather, LR, MR, and HF, respectively, with an acceptable Log(BER) of -2.42 for ultra-FEC limit.
