Shares of Applied Optoelectronics (NASDAQ: AAOI) are on the rise, increasing by 4.76% after hours to $108.86 on Thursday. The company has secured a significant $71 million order for 800G transceivers from a major hyperscale customer, bringing total orders from that client to $124 million since mid-March. 800G transceivers are crucial for high-speed data transmission at 800 Gbps, supporting technologies like artificial intelligence, cloud computing, and next-gen data centers. This order will more than double the company's existing backlog from this client. Deliveries for the initial $53 million order will start in Q2 and finish by Q3, while the new $71 million order is slated for completion by year-end. Applied Optoelectronics CEO Thompson Lin expressed that the order reflects the customer's confidence in the company.
