Using an osa to measur PMD in the fild-test case

ljw-602

Polarization mode dispersion1
(PMD) is a critical parameter that can potentially limit fiber-based SONET/SDH transmission rates, as high levels of
PMD prevent the transmission of high-speed DWDM, OC-192/STM-64 (10 Gb/s) and OC-768/STM-256 (40 Gb/s) signals.
