  • What is PDL in an optical module

    What is PDL in an optical module

    Polarization dependent loss (PDL) is a measure of the peak-to-peak difference in transmission of an optical component or system across all possible states of polarization. In optical networks, where polarization is not constrained and changes randomly, the PDL of components can accumulate in an uncontrolled manner. It can vibrate along a fixed direction (linear polarization). Abstract—A number of polarization-dependent loss (PDL) measurement methods has been proposed for the characterization of optical devices.
