I don´t want to rain on your parade, but POET stated this:

"the Company has shipped its first 100G Transmit (Tx) Optical Engine sample"

--> so it´s not the beta, it´s the alpha with the production-ready beta already being in preparation.

"The sample delivered to a leading European optical systems company supports a combined transmit and receive Optical Engine product, which has been developed for an innovative 400G transceiver application."

--> so the customer gets a 100G Transmit engine but wants to produce a 400G Transmit/Recieve-Product. It´s a milestone, no more no less.

This press release doesn´t make me hope for orders in 2021. Or is my understanding wrong?
