      when I simulate the basic optical communication system and try to observe the wavelength vs output power variations then I found it is flat over a range of frequencies (1200nm to 1600nm)why???

      plz find the .osd file

      The attenuation property, in the optical fiber, is set to constant, so all wavelengths are experiencing the same loss.

      I have tried by taking attenuation data type from file (not constant) but I am getting the same result.
      can you please send me the some program me file (.OSD) that gives result (something similar )to the curve as given attached file

        Hi,

        If you switch the Optical Fiber component from Constant to From File the loss will act on wavelengths differently. I have attached a simple project to demonstrate this.

        I’m not sure we have a dat file for that entire range, but for SMF-28 we do have the range from 1.4 um to 1.65 um. I have attached the dat file as well, so that you can look at the structure.

        Regards,
        Damian
