Transmittance for Dense Wavelength Division Multiplexing system in non-Kolmogorov turbulence

Abstract

Transmittance for a Dense Wavelength Division Multiplexing (DWDM) system operating in non-Kolmogorov medium is evaluated. MODTRAN (MODerate resolution atmospheric TRANsmission) is also used to include the absorption and scattering effects due to atmospheric gases, aerosols and molecules. Increase in the power law of the non-Kolmogorov spectrum is found to decrease the transmittance at all the wavelengths employed in DWDM. Being valid for all the DWDM wavelengths and for all the power law exponent values of non-Kolmogorov spectra, as the turbulence falls into stronger regimes, the transmittance levels decrease.
