PDL stands for Polarization dependent loss.

Polarization dependent loss describes attenuation that varies with the polarization state of the light. In real fibers and optical components, birefringence and imperfections cause different polarization components to experience different losses, so the amount of signal loss depends on how the light is polarized. This matters because the input polarization can change over time or differ between channels, leading to fluctuations in received power. PDL is measured as the difference, in dB, between the maximum and minimum transmission across all possible polarization states, and it’s a key spec for components like fibers, connectors, attenuators, and WDM elements. The other terms aren’t standard for this concept: phase dependent loss would imply loss tied to phase, while Polarization Dynamic Loss and Power Delay Loss aren’t established terms for this effect.
