PDL is defined as 10 log(Tmax/Tmin) (in dB), where Tmax and Tmin are the maximum and minimum transmittances over the entire polarization state space. Polarization-dependent loss (PDL) has thus emerged...

Mechanical fiber stability is perhaps the most significant contributor to PDL measurement accuracy. Unfortunately, such stability can also be difficult to maintain.

In this paper, we propose polarization-wise power profile estimation (PPE) based on a linear least squares algorithm to estimate the value and location of excessive PDLs.

Polarization Dependent Loss (PDL) Any asymmetry in the fiber waveguide will tend to encourage slightly more loss to one polarization mode than the other, and this is of course a polarization dependent loss.
