In this work, the performance degradation in a Wavelength Division Multiplexing (WDM) receiver system is analyzed in terms of power penalty considering the presence of multiple component crosstalk sources. In conventional way, power penalty is calculated considering the presence of all crosstalk sources simultaneously (i.e. worst case) which is not reality in practice and leads to unrealistic estimation. Here a probabilistic approach is adopted which considers all possible probabilistic appearances of the interfering channels and their realistic impact while calculating Bit Error Rate (BER) and penalty. Power penalty considering the presence of signal-crosstalk beat noise is formulated and the effect of the variation of number of interfering channels and crosstalk level are studied for a fixed thermal noise and photocurrent setting of the receiver. In addition the obtained results are compared with the existing worst case analysis model. © 2017 IEEE.

Realistic estimation of power penalty through a probabilistic framework in a WDM receiver with component crosstalk

2017 International Conference on Circuits, System and Simulation, ICCSS 2017

The objective of this work is to analyze the performance degradation in a Wavelength Division Multiplexing (WDM) receiver system in presence of multiple component crosstalk sources and to estimate the value of optimum detection threshold which will ensure minimum Bit Error Rate (BER). For this a probabilistic approach is introduced which considers all probable combinations in the interfering channels and their realistic impact while calculating BER. BER considering the presence of signal-crosstalk beat noise is formulated and the effect of the variation of number of interfering channels, crosstalk level, receiver thermal noise and photocurrent have been investigated and compared to the experimental findings and existing worst case analysis model. Some optimum detection threshold values providing minimum BER are also suggested and compared with the previous results which are essential for improvement of the practical receiver design. © 2016 IEEE.

A probabilistic framework to estimate minimum Bit Error Rate in a WDM receiver with component crosstalk

Component crosstalk causes severe system performance degradation in an optical network. In this paper the influence of the component crosstalk originated from signal-crosstalk beat noise, on the performance of a preamplified WDM receiver is investigated assuming both Gaussian and non-Gaussian model. From the analysis it is evident that for the finite interfering channels the results obtained using non-Gaussian model varies significantly from Gaussian model in terms of BER and the optimum detection threshold for obtaining minimum BER, but as the number of interfering channels approaches large value the variations are minimized. Effects on BER and optimum detection thresholds for minimum bit error rates are compared, summarized and analyzed in both graphical and tabular form for the two different model. © 2013 IEEE.

A comparative study on determination of optimum detection threshold for minimum BER in a WDM receiver with component crosstalk

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. © 2009 IEEE.
