Optical signal-to-noise ratio measurement in WDM networks using polarization extinction

An optical signal-to-noise ratio measurement technique utilizing polarization extinction has been tested in a back-to-back configuration and along a 940 km fiber route between Germany and Austria. We discuss benefits and practical limitations of the technique.
