Love this bit of the article.

Along with Celestial AI and other yet-to-be-named partners, ADVA is among the earliest adopters of POET’s technology. With the POET Optical InterposerTM, the industry that has struggled to find a reliable and cost-efficient solution to achieving higher speeds of data transfer can now architect 400G, 800G, 1.6Tbps and 3.2Tbps pluggable transceivers.

POET have just annouced they have the solution for the bottlenecks in the data centre industry and that's just the start of it.  Would be great if they could capture just 1% of the $900B photonics industry...! I don't need to do the math!!
