QSFP-DD is the future. Mark talks about this around 7:05. The same way that XENPAK/X2/XFP and CFP/CFP2/CFP4 were 1) time-to-market module form factors, 2) were larger than the preceding technology, and 3) ended up giving way to the module that maximizes system density and multi-rate use cases. So with QSFP-DD right around the corner, the question is: why take the detour with OSFP or CFP8?
Mark is spot on! Yes, let's avoid the 'Form Factor' journey for 400 GbE !
