PDL stands for what in fiber optics?

Polarization-dependent loss is the difference in attenuation that a fiber optic component or link imposes on light depending on its state of polarization. Because fibers and many components aren’t perfectly isotropic, different polarization states can experience different losses as light passes through. This difference is typically expressed in dB and can cause fluctuations in signal power, especially in high-speed or tight-budget systems. It’s distinct from polarization-mode dispersion, which is about delay differences between polarization modes rather than loss differences. The other phrases aren’t standard terms in fiber optics for describing this effect.
