Why is measuring polarization mode dispersion (PMD) necessary for
According to ITU-T G.650.3, testing PMD is required for fiber links supporting data rates ≥ 10 Gbit/s or with lengths ≥ 10 km. The appropriate test and measurement (T&M) solutions are

Strictly speaking the PMD is affected by both the delay between the axes, GVD, and any polarization dependant loss, PDL, though it is often assumed to be valid that there is no PDL in a fiber under test.
The FOA Reference For Fiber Optics
Since PMD varies over time, a single test becomes an average and tests at a later time may be done for comparison. There are a number of commonly used test methods for PMD, some of which are limited
