Nice summary:

"Fortunately, POET has announced customers and partnerships. There’s publicly available information, and evidence to support their technology and product development to the degree it is now well past just company talk. Would a company like Lumentum post POET's NR on their own website if they weren't confident the partnership stands a reasonable chance of success? Probably not. One would expect (hope) these types of partner/collaboration NR's and announcements to become more significant and meaningful as commercialization of POET's technology takes off.

Demonstration of support for the technology through announced collaboration/partnerships backs up the notion there’s more than just words from POET out there. A simple google search will yield the following:

• Celestial AI has announced that POET is developing light engines for their AI/ML technology

• Broadcom has been identified as supplying CW lasers for the POET platform

• Lumentum has announced they are supplying DM lasers for the POET 400/800/1.6T platform, which will be used for applications in the hyperscale data-centre market.

• ADVA has announced that POET is an integral part of their newest offering (in fact, it likely couldn't have been achieved without POET). ADVA’s words, not POET’s:

• POET established the $50M JV SPX with Sanan IC, where Sanan is responsible for all CAPEX to ramp production, no cash contribution on POET’s part. SPX will manufacture all 100G and 200G POET based engines globally, and 400G in China. Why would a major player like Sanan put up all the money if they weren’t supremely confident in the tech?

• Silterra is actively producing finished and validated OI chips, that have been integrated into alpha and beta samples for customers, designs of which have now been locked-in for production.

• 8 actual products for demo at OFC in a few weeks, some of these finished commercial versions

• POET has started sampling 400G FR4 and 800G 2xFR4 receive optical engines (RXOEs) for LuxshareTech, a global technology provider for data-communication facilities and enterprise-level products to enable the sale of power-efficient and cost-optimized 400G and 800G transceiver solutions.

• Shenzhen Fibertop Technology Co., Ltd., (“Fibertop”) a transceiver module supplier, has committed to incorporate POET Optical Engines in its line of optical modules as soon as production Optical Engines are available.

• Even the company’s most recent announcement regarding the formation of the new BFYY in China, whose sole line of business is to manufacture POET based transceivers for the sizeable Chinese telecom market (and beyond). I suspect many underestimate the potential of this seemingly insignificant announcement.

Of course, the list above is probably not exhaustive, and does not include those still shrouded in NDA’s. I think at last count 6 to 7 unnamed customers and engagements, time will tell about those.
