Very nice video, but could be better if it explained a little more slowly

Hello! An informative tutorial I must say. Although I have a question regarding it. The graph you showed for the refractive index for NZDSF, is it really for NZDSF? because I was searching for some information regarding the index profile and I saw someone mentioned this profile to be of Zero DSF. Can you please share the book or reference from where you took this refractive index profile graph because I'm confused if it is for NZDSF or ZDSF. That would be so helpful for me. Thank you.
