Yes, on OSFP we have the possbility of making this right again for 400G. It will not have the same backward compability as QSFP-DD and not the same faceplate density (but close enough i would say). But in return we would most likely see longrange optics MUCH earlier in the lifecycle of 400G > > It's the vendors that chose to go for QSFP due to the density options in a > single RU chassis. > > Thanks, > > Sabri
