A method for measuring the signal - rausch distances osnr in a wavelengths - multiplex (- wdm) - transmission system

摘要

It is a process for the measurement of the signal - rausch distances in a wavelengths - multiplex (- dwdm / wdm) - transmission system is described, in which the effect of the amplified spontaneous emission by means of various ase arranged in the transmission system component, such as, for example, various filter. The measuring points of the signal - and noise powers for the measurement of the signal - rausch distances, depending on the spectral characteristics of these components selected from a network - management.
