In this paper, the influence of the In-band crosstalk-crossstalk beat noise on the bit error rate (BER) of a preamplified WDM receiver is investigated assuming Gaussian approximation.Abstract:
In this paper, the influence of the In-band crosstalk-crosstalk beat noise on the Bit Error Rate (BER) of a preamplified WDM receiver is investigated assuming Gaussian approximation. From the analysis and comparison it is evident that in case of many interferers the crosstalk-crosstalk beat noise can significantly affect the value of BER and modify the optimum detection threshold for obtaining minimum BER. Bit Error Rate including the presence of crosstalk-crosstalk beat noise are calculated and the effect of the variation of number of interfering channels have been investigated which is essential for improvement of the practical receiver design.read more

Derivation of analytical expressions for the bit-error probability in lightwave systems with optical amplifiers
TL;DR: In this article, the authors derived the bit-error probability for a lightwave communications system using an amplitude-shift-keying (ASK) pulse modulation format and employing optical amplifiers such that amplified spontaneous emission noise dominates all other noise sources.

Scaling limitations in transparent optical networks due to low-level crosstalk
Evan L. Goldstein,L. Eskildsen +1 more
TL;DR: In this paper, the authors show that transparent optical networks corrupted by interferometric signal-crosstalk beat noise from only 8 crosstralk fields, which is the number of fields required to generate in-band signal-to-noise.

BER floors due to heterodyne coherent crosstalk in space photonic switches for WDM networks
TL;DR: In this paper, the authors compared the dependence of switch architecture and size on the rate of coherently induced bit errors and found that the minimum crosstalk required to avoid coherent errors can vary from -10 dB to -42 dB depending on the switch architecture, size, and requirement for short-term BER stability.

Homodyne crosstalk in WDM ring and bus networks
TL;DR: In this paper, the combined effects of coherent and incoherent crosstalk in WDM ring and bus networks were examined and a Monte Carlo simulation was used to show that when both coherent and coherent CRSs are considered, BER floors are likely to be higher than previously appreciated.

Study of Component Crosstalk and Obtaining Optimum Detection Threshold for Minimum Bit-Error-Rate in a WDM Receiver
Santanu Sarkar,Nikhil Ranjan Das +1 more
TL;DR: In this article, the 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 rates.
