action or reaction,

Your English is just fine. This statement is a very big deal though. Suresh and his team offer a solution to 800G and 1.6G  Even though it is not right now, it soon will be. The design process is mapped out with the 400G TX/RX engine Poet currently demonstrated. It also creates a large revenue path for a long time to come. The guy is brilliant. You have to give it to him.

But. That dam carrot we have been salivating over and just out of reach is about to be devoured! The company is telling us that we will be in full production with four customers by years end. Another four plus two more in China that will be on board the first half of 2023. Ten customers in full production!!!

Read the excerpt from the recent blog again. If what they say is true we only have to wait until the end of this year. 

Vivek said that SPX is ready for mass production!!!

6. POET expects to start sampling 800G/1.6T Optical Engines in the first half of 2023. Does that mean the company will not make revenue until those products have been evaluated by customers?

No. As we have stated, POET will be in full production for four products by the end of 2022. Those products are: 100G CWDM4 TX, 100G CWDM4 RX, 200G RX, and 400G RX. And then there will be another four products in production in the first half of 2023. On top of that, customer engagement and design-in activity has gained momentum, with at least two customers in China to get into production early next year. And we have multiple design-in activity with other module customers.
