Method for measuring the optical signal-to-noise ratios OSNR in a wavelength division multiplex (WDM) transmission system

   
   

A method for measuring the optical signal-to-noise ratio in a Wavelength Division Multiplex (DWDM/WDM) transmission system is described in which the effect of the amplified spontaneous emission ASE differs through different components located in the transmission system such as various filters, for example. The measuring points of the signal and noise powers to measure the optical signal-to-noise ratio are selected in accordance with the spectral characteristics of these components by a network management system.

Een methode om de optische signal-to-noise verhouding in een Samengesteld (DWDM/WDM) de transmissiesysteem van de Golflengte wordt te meten van de Afdeling beschreven waarin het effect van de vergrote spontane emissie ASE door verschillende componenten verschilt die in het transmissiesysteem worden gevestigd zoals diverse filters, bijvoorbeeld. De metende punten van de signaal en lawaaibevoegdheden worden om de optische signal-to-noise verhouding te meten geselecteerd overeenkomstig de spectrale kenmerken van deze componenten door een netwerkbeheersysteem.
