Inspired by the post from "Murrayj1" on stocktwits I did some digging.
The Baily product was shown at OFC in 2023 and contains 8 optical engines. As far as I understand it can deliver 6.4 TB so its 8x800 GB. A video of the OFC is here: https://www.youtube.com/watch?v=yDtN-jflOSI&ab_channel=NextGenInfra (still confused about the 6.4 tb statement).
Found this image here on a chinese website https://pic1.zhimg.com/80/v2-3a26ccad25a4242f77e669b327385d98_720w.webp stating a power reduction of 30% and cost saving of 40%.
The number indicate POET inside. Just wishful thinking or a viable assumption?
