Good question.

The FAQ some time ago about SANAN said:

"Which segments of the Ethernet market will the JV target and what type of customers will the JV serve? The JV will target customers who build and/or use 100G, 200G and 400G transceiver modules with several variants of POET OI-based Optical Engines. Customers for optical engines include companies that build transceiver modules, along with system integrators and data center operators, who often specify the suppliers and components that make up an optical transceiver module."

Based on the slide "Manufacturing : From Wafers to Optical Engines to Modules" it "seems" that future plans are to produce full modules? But under "modules", SANAN isn't mentioned. Only POET is mentioned. So maybe only POET is planning to make the modules, without SANAN? This could explain why this wan't mentioned in the FAQ above. 

I'd like to know the answer too.

Anyway I think selling modules under the name POET with POET's optical engines... exciting.
