The 5G mobile network deployment goal is to provide 1-10 Gb/s wireless signal for the end user. For that purpose, polarization multiplexing (POL-MUX) can be utilized to double the bandwidth efficiency. At these bit rates, the polarization mode dispersion (PMD) becomes very problematic as a bit rate limiting factor. It influences the polarization cross talk and polarization extinction ratio (PER). We propose the application of single side-band Pol-Mux techniques for radio over fibre system achieving this way increased capacity. The performance of the orthogonal coherent polarization multiplexed (Pol-Mux) in a radio over fibre system for multi-user MIMO using linear polarized antennas technique is improved by using polarization beam splitter/combiner and polarization controller with different polarization phase shift, different fibres length, and different bit rate.
