FREMONT, CA / ACCESS Newswire / March 31, 2026 / Aehr Test Systems (NASDAQ:AEHR), a leading provider of test and burn-in solutions for semiconductor devices used in artificial intelligence (AI), data center, automotive, and industrial applications, today announced it has received an initial order from a major new customer that is a global leader in networking products and solutions and a major supplier to the data center optical transceiver market. The customer is developing advanced silicon photonics-based transceivers for data center networking and optical I/O applications to address the rapidly accelerating demand for high-speed fiber optic communication links in hyperscale AI and cloud data centers.
The order includes multiple systems for both engineering qualification and high-volume production, including a FOX-XP™ wafer-level burn-in (WLBI) system configured to test nine wafers in parallel, a fully integrated WaferPak™ Auto Aligner, multiple FOX-NP WLBI systems, and multiple full sets of FOX WaferPak full-wafer Contactors for production, engineering and new product introduction. The systems are scheduled to ship in Aehr's fiscal fourth quarter ending May 29, 2026. The customer has also provided Aehr with a forecast for additional systems, with follow-on orders possible as early as later this calendar year as it ramps capacity to support next generation hyperscale data center deployments.
"Data center architectures are rapidly evolving as AI infrastructure scales, driving a major transition from traditional copper interconnects to fiber optic communication links to meet the increasing demands for bandwidth, latency, signal integrity, thermal performance, and power efficiency," said Gayn Erickson, President and Chief Executive Officer of Aehr Test Systems. "Silicon photonics-based optical transceivers are a critical enabling technology for this transformation, and we believe this order is particularly significant because it comes from a major new customer that is a leading supplier of networking products and solutions for the data center market.
"What makes this win especially exciting is that the customer is purchasing systems for both engineering qualification and high-volume production up front, reflecting the urgency of the ramp now underway to support the massive buildout of hyperscale AI and cloud data centers. We believe this customer engagement further validates WLBI as an increasingly important part of the silicon photonics manufacturing flow and highlights the potential for silicon photonics to become a meaningful long-term growth driver for Aehr's WLBI business.
"We believe this win positions Aehr to participate in what could be a significant multiyear expansion of silicon photonics production driven by the growth of fiber optic interconnects in hyperscale AI data centers."
As data center architectures scale to support AI, cloud computing, and high-performance networking, fiber optic interconnects offer significant advantages over copper wiring, including higher data rates, lower power consumption, longer reach, improved thermal performance, and reduced electromagnetic interference. These advantages are driving rapid adoption of silicon photonics transceivers across hyperscale and enterprise data centers worldwide and increasing demand for cost-effective, production-proven burn-in solutions that can ensure device quality and long-term reliability at volume.
Aehr is the market leader in WLBI for silicon photonics transceivers, with a large installed base at leading global semiconductor and photonics companies. The Company's FOX-XP platform enables high-parallelism, high-temperature, and high-power WLBI, allowing customers to identify early-life failures before packaging while significantly reducing cost of test.
"With our high-power FOX-XP configuration, which we began shipping last year, we offer the highest power-per-wafer WLBI capability in the industry - up to 3,500 watts per wafer," Erickson added. "This proven system is already installed and in production at a world-leading silicon photonics integrated circuit supplier supporting data center and optical I/O applications. In this case, we were able to demonstrate production-ready systems on our manufacturing floor that met the customer's performance and throughput requirements. That capability, combined with our leadership in WLBI for silicon photonics and our ability to support customers from qualification through high-volume production, was a key factor in the customer's decision to select Aehr."
