Applied Optoelectronics has a better chance than Coherent of delivering a 300-400 mW laser with tolerable RIN and linewidth. Its transceiver capacity ramp is also larger and is not gated by Sumitomo's 6-inch InP wafers. Long AAOI against short COHR is an unnecessarily dangerous pair trade idea. x.com 

Applied Optoelectronics is a domestic AI data-center bottleneck winner whose results show exponential operating leverage. EPS jumped 186% quarter over quarter and 138% year over year on an 86% revenue surge, as 800G transceiver economics improve with its Texas and Taiwan fabs reaching prime yields. With the US tightening restrictions on Chinese optical supply chains and the FCC banning new Chinese data-center hardware, hyperscalers are flooding it with high-margin orders. x.com 

Applied Optoelectronics, Lumentum and Coherent face share losses at US hyperscalers to Innolight. Channel checks favor Innolight gaining share in Q2 2026, at the expense of those three. Per @poezhao0605, a $7B Hong Kong IPO, the largest in years and upsized from $5B on strong demand, has cleared its listing hearing. x.com 

Optics and photonics should be among AI's biggest winners as faster GPU networks need optical connections that suppliers cannot expand quickly enough. Lumentum says some components are sold out through early 2029; Sivers is investing $30M to target more than 100M lasers a year, with operations expected in Q4 2027. Potential US restrictions on Chinese transceivers could reshape supply in 2027. Applied Optoelectronics and Sivers are the favorites. x.com  x.com 

Applied Optoelectronics should trade above $150, in part because Lumentum's CEO says its optical components are sold out through early 2029 and it cannot meet roughly 70% of demand for some products through 2027. That industry signal strengthens the case for AAOI's expanding 800G/1.6T offerings after completion of its $600M ATM, with shares around $110. x.com 

Higher optical-fiber use per GPU could expand demand for Applied Optoelectronics. Corning said fully optical scale-up would raise fiber count from about 16 to 160 per GPU; that 10x case is hypothetical for now, with a mix of technologies likely near term, but it shows the direction of travel. x.com  x.com 

Rising 1.6T switching demand favors optical suppliers, though their execution risks vary. Bank of America says the market could grow ~101% annually through 2030. Marvell's leading DSPs and Lumentum's supply-short 200G EML lasers are lowest risk; Applied Optoelectronics' capacity expansion and Fabrinet's customer concentration make them medium risk. Aeluma remains pre-commercial, while Lightwave Logic's polymer modulators are a high-risk moonshot despite its TSM partnership. x.com 

Optical transceiver demand exceeds supply, and 1.6T lifts revenue per module for suppliers able to qualify capacity. Applied Optoelectronics raised at least $1.62B through 2026 ATMs; its last reported monthly capacity was 200,000 modules versus a year-end target above 650,000. Credo expects over $600M in FY2027 revenue across optical DSPs, PICs and modules, not modules alone. Shipments, yields and margins must prove out. Lumentum and Coherent already price in much expected growth. x.com 

Applied Optoelectronics is the US-built option in 800G datacenter transceivers, where there is almost no domestic supply. It is scaling its line in Sugar Land, Texas, while larger Innolight and Eoptolink build in Asia and Lumentum and Coherent are crowded large caps. It also makes its own lasers, which Goldman flags as the binding shortage through 2027. Revenue rose 86% last quarter, with net cash. Risks: a -12% operating margin, concentrated customers, and whether in-house lasers hold at 1.6T. … Show more

Applied Optoelectronics is a high-conviction co-packaged optics play, now affirmed by Astera Labs' CEO. Per @athuinvests's read of his JPMorgan conference remarks, CPO is inevitable for physical reasons, deployments start in 2027 rather than 2029 or later, and Astera is investing heavily in the enormous opportunity. x.com
