Impact of uncompensated dispersion on non-Gaussian statistics in duobinary transmission

Abstract

Abstract. We show through numerical simulation of 10.7-Gbits/s dense wavelength-division multiplexed ͑DWDM͒ duobinary transmission over 800 km of nonzero-dispersionshifted fiber that uncompensated dispersion can introduce significant departures from Gaussian statistics in the receiver current.

Advanced modulation formats for fiber optic communication systems

“…A larger Q value indicates a lower B E R and hence better performance. Note, however, that Equation (86) assumes Gaussian statistics for the noise distribution, an assumption that is often violated in modern communication systems [13][14][15].…”

Performance of alternate-block-inversion modulation format in optical communication systems with no dispersion compensation

“…In this paper, we demonstrate that PASS-ABI can outperform even PSBT for practical systems with large amount of uncompensated dispersion. We take care to optimize system parameters and incorporate practical system impairments, and estimate system performance using nonGaussian statistics [19][20][21].…”
