Abstract
The role of Q-factor and of time jitter in the evaluation of the system per formance has been investigated for return-to-zero (RZ) optically amplified links. We show that, also if the decision variable is not Gaussian, it is p ossible to predict, by means of a limited number of simulations, the condit ions in which the bit-error rate (BER) is lower than a fixed value (10(-9)) , if both the Q-factor and the time jitter are evaluated including patterni ng effects. This analysis has been confirmed by the comparison among simula tions and some experimental results, obtained in the framework of ESTHER an d UPGRADE ACTS European projects, in very different propagation conditions.
