Shares of Applied Optoelectronics Inc. (AAOI) jumped more than 4% in Monday’s extended trading hours after it announced that it received a new volume order from one of its hyperscale customers.

The company, without naming the customer, said it had received an order for 800G single-mode data center transceivers, worth more than $53 million, intended to expand the customer’s network capacity for AI-driven workloads.

After product qualifications, the company expects shipments to start in the second quarter, and be completed by the middle of the third quarter in 2026.

Leadership Take

Founder, Chairman, and CEO of the company, Dr. Thompson Lin, noted the acceleration in AI infrastructure expansion, saying that it required significantly higher bandwidth at scale.

“Our customers are adopting 800G not just for capacity and performance, but to manage long-term operating costs. Deploying 800G now helps to prevent network bottlenecks, improves power efficiency and lowers cost per bit, reducing the need for frequent upgrades,” Lin said.

Meanwhile, the company’s CFO, Stefan Murry, said that the reliable transceiver capacity is critical for the supply chain strategies of AAOI’s customers.

"This early order for 800G is expected to support GPU cluster buildup, in line with our customer's large-scale infrastructure expansion plans,” Murry said.

In addition, Murry said that the deal followed the prior week's announcement of 1.6Tb orders from this same customer, and that the initial 800G volume order, totaling more than $53 million, is likely to be the first of many more orders as the customer scales for rollouts across its clusters and regions.

AI Hardware

Last week, Applied Optoelectronics showcased advanced data center solutions at the Optical Fiber Communications Conference, highlighting its transceiver lineup from 100G to 1.6T and a live 6.4T on-board optics demo.

The company also showcased a 400mW continuous wave laser for 25dBm External Laser Small Form-Factor Pluggable (ELSFP), designed to support high-bandwidth AI systems. The solution will enable robust link budgets for CPO/NPO architectures while ensuring reliability and serviceability for mission-critical GPU clusters, the company said.
