Applied Optoelectronics Inc. (NASDAQ:AAOI) recorded a 3.1% rise in after-hours trading Monday after announcing it had secured a volume purchase from a major hyperscale customer valued at in excess of $53 million. The order covers 800G single-mode transceivers designed for data center use.
The company said the customer intends to deploy the modules to boost network capacity specifically for AI-driven workloads. According to Applied Optoelectronics, shipments are scheduled to commence in the second quarter and are expected to be completed by the middle of the third quarter of 2026, contingent on completion of product qualification processes.
Company leadership framed the order as a response to accelerating demands on AI infrastructure. Dr. Thompson Lin, Founder, Chairman, and CEO of Applied Optoelectronics, emphasized that the expansion of AI infrastructure is increasing the need for higher bandwidth at scale. He noted that customers are adopting 800G technology to curb long-term operating expenses, as the higher-rate modules can help avoid network bottlenecks, improve power efficiency, and reduce cost per bit.
Stefan Murry, the company’s Chief Financial Officer and Chief Strategy Officer, said the order is aligned with the customer's buildout of GPU clusters and its broader large-scale infrastructure expansion plans. Murry pointed out that this 800G order follows last week’s disclosure of 1.6Tb orders from the same customer, and he stated the company expects this to be the first of additional orders as the customer scales rollouts across clusters and regions.
In a separate disclosure filed Monday, a Schedule 13G reported that Jane Street Group, LLC beneficially owns 4,097,237 shares of Applied Optoelectronics common stock, equal to 5.3% of the company’s outstanding shares. The filing indicates shared voting and dispositive power over those shares across Jane Street entities, including Jane Street Capital, Jane Street Options, and Jane Street Global Trading.
