They aren't (yet), these are vaporware. Many amnufacturers are close to
having reliable 40km optics, and several are making 20km+ overpowered
LRs, but ZR and DWDM are still a ways out. There are also some CWDM
units in the works, but because SFP+ doesn't support onboard EDC you
are limited by dispersion to 10km in the traditional 8ch 1470-1610nm
CWDM space over SMF28.
