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. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
