Abstract
A polarization-dependent loss (PDL) determining method includes obtaining two groups of optical powers within first duration, selecting at least one group of target optical powers that satisfy a same power constraint from the two groups of optical powers, where each group of target optical powers includes a first target power and a second target power from the two groups of optical powers, and determining a PDL of the optical device based on the at least one group of target optical powers.
