An analytical approach to determine absolute power transfer due to cross-phase modulation (XPM) and self-phase modulation (SPM) from their spectral characteristics in a multispan intensity-modulation direct-detection (IM-DD) optical system is presented in this paper. Here, dependency of XPM and SPM power transfer on different link parameters like pump power, channel spacing, link length and, bitrate...
The spectral characteristics of cross-phase modulation (XPM) and self-phase modulation (SPM) in multi-span intensity-modulation direct-detection (IM-DD) optical systems are investigated. As constituent parameters, span-length and channel spacing, both are found to be strongly influential regarding XPM and SPM. Short period dispersion managed fibers (SPDMF), to suppress the XPM and SPM induced crosstalk,...
We present a comprehensive theoretical study of four-wave mixing in optical fiber with exploring four fiber types. The four-wave mixing induced crosstalk noise is described by an expression that is based on NLS equation, and it describes the mutual channel interference optical losses in multi channel optical communications system. The corresponding system of equations has then been numerically integrated,...
