Description: The polarisation dependent loss (PDL) is the difference (in dB) between the maximum and minimum values of the channel insertion loss (or gain) of the black-link from point SS to RS due to a variation of the state of polarization (SOP) over all SOPs
What is jnxPMCurPolarDepLoss?
The current polarization-dependent loss (PDL), in units of 0.1 dB, measuring the difference between the maximum and minimum channel insertion loss (or gain) across all possible states of polarization for this link. Admins watch for elevated PDL as a sign of degrading optical components, since it reduces the effective signal margin on the link.
