This is from Macom's website Pure Drive.  This looks like very similar language that Poet uses.  Now with all the links with employees that have worked at Macom and a chip long ago with the word on it that could be Macom could Pure Drive contain the Poet Engine?

Reduction of optical interconnect power consumption upwards of 50% Check

Minimized link latency critical for machine learning and artificial intelligence applications Check

Eliminates costly, redundant signal retiming.  Not sure?

Solves thermal issues associated with discrete DSP Check

Simplified module implementation allowing for greater flexibility. Check

Reduces footprint to meet space-constrained designs.   Check

Scalable up to 1.6TB.      Check

The MACOM PURE DRIVE™ chipset has been designed to support broad dynamic ranges, linear equalization and low noise amplification to enable direct connection to switch and server ASICs. Working together, these linear links can support leading edge throughput while, at the same time, enable specialized functionality of each component in the data path such that power, cost and latency can be minimized.    

The MACOM PURE DRIVE™ chipset includes a 4x100G multi-mode fiber VCSEL driver and a 4x100G single mode fiber EML/silicon photonics driver (die or packaged). Corresponding TIAs are also available as part of the chipset.
