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.

由于极化相关损耗，收发器噪声对断电概率的影响

超出阈值的方法用于研究收发器噪声对由于每跨距极化相关损耗 (PDL) 造成的中断概率的影响。捕获 PDL 对信号的分布效应和放大的自发辐射噪声的仿真模型用于获得 10,000 个链路 PDL 实例的按位可实现信息速率 (BW-AIR) 数据。中断概率是根据 BW-AIR 小于由前向纠错码率确定的阈值来定义的。对于 32 Gbaud、双极化 64 进制正交幅度调制以及均匀和概率形状的星座，评估了中断概率对收发器信噪比的依赖性。
