摘要：
In this paper, bit error rate and power penalty in a WDM receiver system in the presence of component crosstalk with finite interferers are studied using a simplified analysis and some optimum detection thresholds are suggested for minimum bit error rate. Error probabilities are calculated considering a unipolar bit stream of optical signals at the receiver input. Probability density function in the presence of crosstalk deviates from conventional Gaussian function. Effects of receiver noise, number of interfering channels and crosstalk levels on the receiver performance are shown. Optimum detection thresholds for minimum bit error rates in the WDM receiver in presence of component crosstalk are investigated and summarized in tabular form.
