      Hi all,

      I tried to calculate Chromatic dispersion for MMF. I used the reference wavelength = 1354nm, source wavelength = 1354nm, zero dispersion wavelength = 1354nm and zero dispersion slope = 0.097ps/nm^2km and I should get the get dispersion = 0 (i am getting ‘0’ as mathematically ) but in output it shows dispersion. what can I do?

      I attached the file.

      Thanks in advance.

      Hi Sasha,

      I have noticed you have not used the exact values you mentioned here in your simulation, but you have set zero dispersion wavelength and the signal central wavelength the same. However, since the signal has a spectrum of wavelengths, and not just one single wavelength, maybe that is the reason why the signal is still affected by dispersion.

      Regards
