Beanstalk, the 6.4Tbps solution had been briefly mentioned or alluded to in various discussions and presentations over the past couple of years.  The first time I noticed it in a corporate presentation was in the business update conference call in April 2022. (see slide 9).  I suspect there has been ongoing work on this, and perhaps some real progress to date.

As indicated in the article, this product was conceived to address the move to CPO for higher bandwidth, etc.  However, I suspect POET's 1.6T and 3.2T pluggable solutions will reduce the immediate push for CPO, as they provide high speed, lower power and very cost effective solutions using a pluggable form factor, something that was deeemed to too difficult or expensive to pursue (in a pluggable) before POET came along, and likely one of the drivers for CPO in the first place.

CPO will come and POET should be well positioned with this 6.4Tbps solution when it does.
