Abstract :
The paper is on the monitoring of optical telecommunication channels by means of specialized spectrophotometers, called optical performance monitors. An algorithm for data processing is proposed that makes possible the estimation of central wavelength, power and optical signal-to-noise ratio for all channels in parallel. It is demonstrated that it is guaranteeing an acceptable level of measurement uncertainty when applied to the data provided by a low-resolution spectrometric transducer being the constitutive element of an optical performance monitor
