So ADVAs design allows a datacenter to upgrade to 400G equipment while still handling legacy 100 and 200G at the same time. Since they mention 1.6T and 3.2T in the release, they probably see a nice market opportunity allowing operators to flexibly bring on higher rates without obsoleting all the older equipment, as the mix will be ever more complicated as time goes on. Hope the strategy pays off for them and POET.
