適用范圍：This part of IEC 61280 defines the averaged Q-factor and provides a procedure to measure itby using amplitude histogram parameters such as the standard deviation and average level.The averaged Q-factor and amplitude histogram parameters are useful for monitoring changesin optical signal quality in installed optical networks. The average Q-factor is correlated withthe traditional Q parameter of a given optical channel.With the averaged Q-factor test method signal, quality degradations due to optical signal-tonoiseratio (OSNR) degradation and to waveform distortion can be monitored:OSNR degradation, due to the following causes:– accumulation of amplified spontaneous emission (ASE);– transmission line loss;– channel crosstalk;waveform distortion, due to the following causes (usually simultaneously present):– chromatic dispersion;– polarization mode dispersion (PMD);– optical nonlinear effects.
