Abstract

This paper investigates downstream transmission of 112 Gb/s coherent next generation-passive optical network II (NG-PON2) over multiple end users by deploying different polarization multiplexed phase shift formats. Here, a simulation over B2B configuration and fiber based optimization is performed for maximum reach, provided nonlinear propagation of optical signal with amplification over uncompensated link. The analytical behaviour of the proposed NG-PON2 is numerically measured in terms of receiver sensitivity, bit error rate, optical signal to noise ratio, error vector magnitude and constellation diagram with acceptable performance. Exceptionally good power budget is also calculated for different modulation formats. This analysis enables an efficient understanding of NG-PON2 under the influence of different polarization multiplexed formats along with varying number of end users.
