Why we use anomalous dispersion in FWM?

[eahaidar]

Hello everyone
I need to know why is it so important to use anomalous dispersion in FWM which four wave mixing and is there any experiment using HNLF high nonlinear fiber ??
Any papers about that I tried. To look but nothing

Would be nice if you explained your abbreviations.
I suppose in Four Wave Mixing (?), simply the interaction is strongest in the region of anomalous dispersion.

Yes FWM is four wave mixing , so any thoughts ?
