Estimating the Outage due to Polarization Dependent Loss Based on the Bit-wise Achievable Information Rate for Probabilistically Shaped 64-QAM

The implication of per-span polarization dependent loss (PDL) on the statistical behaviour of the bit-wise achievable information rate (BW-AIR) is investigated for probabilistically shaped and uniform 32 Gbaud, dual-polarization 64-ary quadrature amplitude modulation. For constellation entropies ranging from 5.6 to 6 bits/symbol, and the number of spans ranging from 4 to 24, a simulation model tha...
