IN Brief:
- AOI reported second-quarter revenue of $191.9 million, up from $151.1 million in Q1.
- 800G product volumes more than doubled sequentially as total transceiver capacity approached 200,000 units per month.
- AOI expects capacity for 800G and 1.6T products to reach around 650,000 units per month by year-end.
Applied Optoelectronics (AOI) more than doubled 800G transceiver volumes sequentially during the second quarter as the optical-component manufacturer continued a rapid expansion of production capacity for AI and cloud infrastructure. Revenue reached $191.9 million, compared with $151.1 million in the first quarter and $103 million a year earlier.
The production increase is running alongside a considerably larger manufacturing build-out. AOI said its total manufacturing capacity is approaching 200,000 units per month and expects to be capable of producing around 650,000 800G and 1.6T products per month by the end of 2026. The company also expects demand for its high-speed optical products to remain above available production capacity through the middle of 2027.
That capacity target puts the second-quarter results into a different category from a conventional semiconductor earnings increase. AOI is attempting to raise output by more than three times from its current monthly capability while customers are simultaneously moving towards faster generations of optical links. The manufacturing requirement extends from internally produced lasers and optical components through alignment, assembly, electrical integration, test, and final transceiver qualification.
The physical footprint is expanding accordingly. Construction began in July on two adjacent properties in Pearland, Texas, adding nearly 400,000 square feet intended to support additional 800G and 1.6T transceiver production. The development forms part of a wider Houston-area manufacturing expansion and follows a series of high-volume orders for 800G devices from hyperscale customers.
Moving from 800G towards 1.6T increases the engineering burden as well as the nominal link speed. Higher aggregate bandwidth requires faster electrical and optical channels, tighter signal-integrity control, more demanding thermal design, and increasingly efficient conversion between electrical data and light. Packaging and test processes must also keep pace because a higher-speed module that performs correctly in development still has to reproduce those characteristics across hundreds of thousands of manufactured units.
AOI’s vertically integrated model gives it control over several of those stages. The company develops laser devices and optical components before integrating them into subassemblies and complete networking products, reducing reliance on a fully external optical supply chain. Vertical integration can shorten feedback between device engineering and module production, although it also means capacity has to be balanced across multiple processes rather than simply increasing final assembly.
The second-quarter gross-margin figures illustrate some of the pressure accompanying the ramp. GAAP gross margin was 27.7%, down from 29.1% in Q1 and 30.3% a year earlier, while non-GAAP gross margin was 29.8%. At the same time, AOI returned to non-GAAP profitability with net income of $5.5 million after recording a non-GAAP loss of $4.9 million during the first quarter.
For the third quarter, revenue is forecast between $255 million and $290 million. That guidance represents another sizeable increase from Q2 and makes manufacturing execution central to the outlook. Customer demand can support a larger order book, but revenue can only follow once qualified modules pass through assembly, optical alignment, test, and shipment at the required rate.
The expansion is also occurring while transceiver architectures are evolving. An 800G module remains a high-volume requirement for current AI networks, while 1.6T products are being qualified for the next step in switch and accelerator connectivity. Running those generations in parallel creates additional complexity around equipment utilisation, process control, component sourcing, and customer-specific qualification.
AOI’s Q2 figures provide evidence that the first part of the capacity ramp is already translating into output, with 800G volumes more than doubling from the previous quarter. The harder manufacturing test now lies ahead: increasing monthly capability from roughly 200,000 units towards 650,000 while maintaining optical performance, yield, and delivery as 1.6T moves into the production mix.
