I'm confused as well, if you look at the company graph "Product Roadmap driven by Customer Engagement" it clearly shows Q3 "Production" for 100/200G CWDM4 Optical Engines, 400G Light Engine and  400 G FR4 Receiver.   This release suggests "early" 2022 for production, can someone clarify if I'm missing something here?  Is it a differentation between mass and initial production I'm not understanding or is this a slight delay in the previous released timeline?  I'm just trying to get to reality here, no negative or positive spin or intent.  Thanks.
