Dear damian,I am so sorry to reply you late.I have upload my attachment（optisystem 7 in win7）.I want to simulate a system to demnonstrate the influence of EDFA in the bidirectional optical link.In my application ,i want to set the time window to almost 1 second.however,It occurs to a error I refered to last time.is it because that my computer is out of memory.(my computer has 4g memory ).I also have some questions to ask you!
1、it seems that The device optical power meter does not measure all the optical power but some wavelength power near the center wavelength.
2、I want to know whether the OSNR the device wdm analyzer measured include the information I modulated to the laser.
thank you for you reply in advance.
