Applied Optoelectronics (AAOI) is moving higher after disclosing an upsized $71 million order for 800G single-mode data center transceivers from a major hyperscale customer. The company said the additional order brings total orders from that customer to $124 million since mid-March, which it expects to more than double the existing backlog tied to that customer.

AAOI said shipments for both the previously announced initial order (more than $53 million) and the new $71 million order are expected to begin in Q2 2026, contingent on product qualification. The company expects the initial order to be completed in Q3 2026, with the new upsized order delivered by year-end 2026, and it also disclosed it recently shipped the first 10,000 units of an 800G single-mode transceiver order to another hyperscale data center customer.

The market is treating the upsized order as a read-through on accelerating AI data center networking spend and on AAOI’s positioning in the 800G upgrade cycle. By increasing near-term order visibility and tying deliveries to specific time windows (Q2 start, year-end completion), the announcement puts focus on execution—qualification, manufacturing throughput, and on-time fulfillment—as the company attempts to convert backlog into revenue over the next several quarters.
