Hi Monk, I respectfully disagree the chip is labelled AdvR and not ADVA.  AdvR provides products for primarily research oriented low-volume niche applications, not high volume datacom.  The chip pictured in the video is the LightBar, designed as a high-performance remote laser source for 400G, 800G and Co-Packaged Optics applications in data Centres. Potential customers for such products are Cisco and ADVA, amongst others.  AdvR: wrong products, and logo is spelled with a mix of capital and small letters.  They simply don't fit all that well as a LightBar customer, IMO.
