re: Huawei Deploys 40G in RussiaFrom the headline you get the impression that Huawei has done 40G for +1000km without regeneration. In fact this seems to be more like their beta stage inverse mux running 40G on 4 x 10G SuperWDM channels on a dispersion compensated network. I believe that they'll have still a long way to go before being able to do 40G single wavelength on that distance in a real life network.
