Abstract :
An optical performance monitoring method based on synchronous sampling and different computation models has been used to investigate the effect of modeling errors on estimating the Q factor. The results show that modeling errors can be minimized and Q accuracy improved by giving more weight to the transition data points. This was accomplished by converting the linear sampled data to the log domain or using a correction weight to fit the linear data. The estimated Q showed good correlation with measured Q from an OC48 back-to-back experimental measurement at different optical power levels.
