A polarization-dependent-loss compensation scheme was experimentally demonstrated in a multi-stage system with distributed ASE noise. The effect of frequency dependency of polarization-dependent-loss could be ignored even the polarization-mode-dispersion was 10ps. The experimental results showed 2dB Q improvement by single processing.

PDL in Optical Links: A Model Analysis and a Demonstration of a PDL-Resilient Modulation
The New Spatially Balanced signaling, an optimal 4D modulation based on this simplified model, is designed and its performance through numerical simulations and experimentally over a transmission in a recirculating loop with in-line PDL is explored.
Estimating the Outage Probability Due to Polarization Dependent Loss Using Threshold Exceedances
The method of threshold exceedances is used to reliably estimate the outage probability due to per-span polarization dependent loss (PDL) using bit-wise achievable information rate (BW-AIR) data obtained using a simulation model that accurately captures the effect of PDL on both the signal and amplified spontaneous emission noise.
