Abstract
The modern dense wavelength division multiplexing (DWDM) management system has no a priori knowledge of alien wavelength parameters. The result of this is unforeseeable impact of alien wavelength parameters on friendly wavelengths quality. The numerical results of the impact of alien wavelength on optical transmission quality are presented, and experimental demonstration based on Alcatel–Lucent 1830 Photonic Service Switch PSS 32 transmission system is shown. The obtained results indicate that alien wavelength bandwidth must be restricted.
