Abstract
Terabyte and petabyte speed require very broadband optical fibers and the same components. The new single mode optical fibers should have the required characteristics: chromatic dispersion (CD), polarization mode dispersion (PMD), optical nonlinearities, optical bandwidth, which has a special application, and architecture [1]. The achievement of terabit and petabit transmission rates with growth number of channel of the WDM systems leads to a decrease of channel density and a decrease of the distance between adjacent channels. Increases both the chromatic dispersion and polarization mode dispersion, especially with increasing nonlinear effects. The result of such effects affects the dispersion length. Nonlinear effects appear in the form of: scattering effects (Brillouin and Raman), Kerr effects: self-phase modulation (SPM), cross-phase modulation (XPM), four-wave mixing (FWM), modulation instability (MI) and soliton formation [2]. The effect of ÑD and PMD on the dispersion length of PMD under strong SPM influence is considered in the article.
Keywords: chromatic dispersion, polarization mode dispersion, self-phase modulation, dispersion length, nonlinear effects.
