Simple method to measure OSNR in transmission systems with channel filtering

A simple method to estimate the OSNR in transmission systems with a strong channel filtering and spectral broadening is presented. The method uses the measured spectra from optical channel monitors at optical add-drop multiplexer and dynamic gain equaliser locations and requires no additional equipm...
