Read MoreHide Full Article
Key Takeaways
AAOI's data center revenues rose 69% Y/Y to $74.9M in Q4 2025 on strong transceiver demand.
Applied Optoelectronics expects 800G to become its largest data center revenue driver in 2026.
AAOI plans the capacity of 500,000 monthly 800G and 1.6T units by the end of 2026.
Applied Optoelectronics (AAOI - Free Report) is preparing to increase production of its 800G optical transceivers as demand from hyperscale data center customers continues to rise. Management expects its 800G optical transceivers to become the largest contributor within the company’s data center segment starting in the second quarter of 2026.
In the fourth quarter of 2025, AAOI reported data center revenues of $74.9 million. The metric increased 69% year over year and 70% sequentially. Growth was driven by strong demand for high-speed transceivers. Sales of 400G products increased 141% year over year, while 100G product sales rose 54% on a year-over-year basis.
Applied Optoelectronics has received an 800G buying order from a major hyperscale customer during the fourth quarter after the successful qualification of its 800G modules. Another existing hyperscale customer has indicated plans to start ordering 800G products. In addition, a new hyperscale customer has begun discussions to qualify AAOI’s 800G and 1.6T transceivers.
AAOI ended 2025 with about 90,000 units per month of 800G production capacity. The company forecasts demand for 800G modules to exceed the company’s production capacity through mid-2027. To support this demand, AAOI is expanding its manufacturing footprint in Texas. The company has signed a lease for an additional building in Sugar Land, Texas, where construction has already started. This facility will help increase production in 2026.
By the end of 2026, the company expects to have the capability to produce more than 500,000 units per month of 800G and 1.6T products. Looking ahead, if the 800G ramp progresses as expected, it could support further growth in AAOI’s data center segment. The Zacks Consensus Estimate for 2026 and 2027 revenues indicates a year-over-year increase of around 107.6% and 90.1%, respectively.
