Abstract
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.
