Hi all,
The Set OSNR is set for 15 dB in the file attached by Nadzreen in his question. I have used two power meters, one before and one after the Set OSNR component. When I run the simulation, the optical power meter before the Set OSNR reads -19.367 dBm for signal power and -100 dBm for noise power, while the one after Set OSNR reads -22.378 dBm for signal power and -100 dBm for noise power. Both before and after the component, the OSNR seems to be much more than that. Am I right? So What happened to 15 dB OSNR that the component was set for? Thank you.
Regards
