text: Thus, if fiber dispersion is high (as with standard NDSF in the 1550 nm band, typically around 17 ps-nm-km) the effects of FWM are minimal for channel spacings greater than about 25 Ghz (if channel spacing is reduced below about 15 GHz, the effect of FWM can be severe even on standard fiber).
