AI Optical Communication Demand Explodes! AAOI Reports Strong Earnings: 800G Revenue Soars Over 10x, 1.6T Poised for Volume Ramp

Artificial intelligence (AI) data centers continue to expand globally, fueling rising demand for high-speed optical communications. U.S.-based optical module manufacturer Applied Optoelectronics (AAOI-US) recently released financial results that exceeded market expectations, acting as a catalyst that ignited the entire optical communications sector on Friday (the 7th). Market analysts interpret AAOI’s strong performance in its data center business as a clear signal that demand for high-speed optical interconnect products in AI computing infrastructure remains exceptionally robust.

AAOI reported second-quarter revenue of $191.9 million, an 86% year-over-year increase. Data center business revenue surpassed $100 million for the first time. Excluding special items, earnings per share (EPS) were $0.06, exceeding both market expectations and the upper end of the company’s own financial guidance.

Looking ahead to the third quarter, AAOI forecasts revenue between $255 million and $290 million, maintaining its full-year revenue target of approximately $1.1 billion.

Following the earnings release, capital rapidly flowed into optical communications stocks. Coherent (COHR-US) surged about 13% in a single day, while Lumentum (LITE-US) and Corning rose approximately 6% and 5%, respectively. AAOI’s own stock price climbed about 9%.

Analysts believe AAOI’s earnings report is not just good news for a single company, but may send a positive signal to the entire optical communications industry. As AI data centers continue to expand, faster data transmission between servers, GPUs, and switches is required, making optical transceivers an indispensable component of AI infrastructure.

Coherent, AAOI, Lumentum, and Corning (GLW-US) are all deeply involved in this market and are therefore viewed by investors as 'picks and shovels' plays in the AI infrastructure space.

Notably, both Coherent and Lumentum are scheduled to release their latest earnings reports next week, and the market is closely watching whether they can replicate AAOI’s strong performance. Analysts expect both companies to maintain revenue and profit growth, given the continued strength in AI data center demand.

It is worth noting that both Coherent and Lumentum have capital or business ties with NVIDIA (NVDA-US), further increasing market attention on their AI optical interconnect strategies.

400G Modules Remain Core, 800G Revenue Soars Over 10x

From AAOI’s product mix perspective, demand for high-speed products in the data center segment is rapidly shifting toward higher transmission rates.

In Q2, 400G optical module revenue reached $48.4 million, more than quadrupling year-over-year, and remains a key revenue source for the data center business. However, in comparison, 800G product growth has been even more dramatic.

AAOI’s 800G revenue in Q2 reached $12.8 million, up over 10 times year-over-year and more than doubling from Q1. The company further expects 800G revenue in Q3 to grow nearly fivefold compared to Q2.

This indicates that AAOI’s data center product portfolio is rapidly upgrading, with the growth engine shifting from legacy products like 100G and 400G toward higher-speed modules such as 800G and even 1.6T.

Demand Exceeds Supply by 20%–40%: Production Capacity is the Key Bottleneck

During the earnings call, AAOI’s management revealed that current customer demand exceeds the company’s supply capacity by approximately 20% to 40%. This suggests that market demand is not the limiting factor for revenue growth; instead, the real bottlenecks lie in capacity expansion, supply of key components, and the customer qualification progress for next-generation 1.6T products.

According to CFO Stefan Murry, AAOI’s current monthly production capacity for 800G and 1.6T products is approaching 200,000 units, a significant increase from about 100,000 units at the end of Q1.

AAOI expects monthly capacity to exceed 650,000 units by the end of 2026 and further increase to over 930,000 units by the end of 2027, with more than half of that capacity coming from its Texas facility.

In addition to 800G, 1.6T is seen as AAOI’s next major growth engine.

Company management stated that AAOI is about to become the fourth supplier qualified by a major hyperscale data center operator for its 1.6T products. Certification is expected to be completed within the next 2 to 3 weeks, with shipments starting by the end of Q3 and volume ramping in Q4.

AAOI CEO Dr. Chih-Hsiang (Ted) Lin expects 1.6T transceiver revenue in Q4 to exceed $70 million and believes there is significant room for further growth in Q1 next year, with the possibility of quarterly revenue doubling.

Looking further ahead, the company projects that by mid-2027, monthly revenue from 100G and 400G products will be around $90 million, 800G around $217 million, and 1.6T around $164 million. Combined monthly revenue for data center optical transceivers could reach approximately $471 million.

However, this growth roadmap carries supply chain and manufacturing risks, dependent on the coordinated progress of equipment installation, customer qualification, material supply, and manufacturing yield.

AAOI acknowledged that supply of key 1.6T components such as DSPs and TIAs remains tight, and the primary constraint on 1.6T deliveries in Q4 will be materials, not production capacity itself.
