"At present, the company's 100G CWDM4 transmitter (Tx) and receiver (Rx) optical engines have been mass-produced ; 400G/800G receiver (Rx) optical engines have also entered mass production, of which 800G 2×FR4 Rx OE has begun batch shipments to strategic customers."
Oh, I like......these words "have been mass produced" "entered mass production" and "begun batch shipments to stratigic customers" all have a nice ring to it like "Cha-Ching."
