Analysis of Crosstalk in WDM Systems Using Spectrum-Sliced Light Sources Between Laser Sources

摘要

In this paper, we compared the effects of crosstalk in WDM systems using laser sources between using spectrum-sliced light sources by using the Gaussian noise approximation. Compared with the system using laser sources, the intraband crosstalk in the system using spectrum-sliced light sources are much less sensitive by signal power and crosstalk power, this is mainly because the spectrum-sliced light source have relatively broad optical bandwidth, the signal-crosstalk beat noise is reduced rapidly as the beat components become spread outside of the receiver's bandwidth.
