Applied Optoelectronics reported a 127.5% year-over-year revenue increase in the third quarter to $269.9 million, describing record growth driven by demand for high-speed data-center transceivers linked to artificial intelligence. Data-center sales rose 254%, while the company faced product-transition challenges and disclosed an order backlog valued at $400 million to $450 million. Orders now exceed production capacity through 2027, and the company signed a conditional deal with a hyperscaler whose potential value was not fully stated in the supplied report.
