Impact of Transceiver Noise on the Outage Probability due to Polarization Dependent Loss

The method of threshold exceedances is used to investigate the impact of transceiver noise on the outage probability due to per-span polarization dependent loss (PDL). A simulation model that captures the distributed effect of PDL on the signal and amplified spontaneous emission noise is used to obtain bit-wise achievable information rate (BW-AIR) data for 10,000 instances of the link PDL. The outage probability is defined in terms of the BW-AIR being less than a threshold determined by the forward error correcting code rate. The dependence of the outage probability on the transceiver signal-to-noise ratio is assessed for 32 Gbaud, dual-polarization 64-ary quadrature amplitude modulation with uniform and probabilistically shaped constellations.
