WhiteLine Daily said the latest earnings round reinforced the same industry message: demand for optical interconnect products remains strong, with 800G already shipping at volume and 1.6T beginning to ramp. Applied Optoelectronics reported $108 million in second-quarter data center revenue, up 140% year over year, and said demand could stay above capacity through at least mid-2027. The company is expanding its U.S. manufacturing base and is targeting monthly capacity of more than 650,000 units by year-end, but near-term execution still depends on line ramp, yield, and delivery speed. MACOM offered a second signal from upstream, reporting $342.2 million in quarterly revenue, up 36% year over year, and a next-quarter revenue guide midpoint of about $420 million, above prior market expectations. Management also flagged shortages in InP DFB lasers, suggesting demand for pluggable optical modules is now pushing constraints back into the laser supply chain. WhiteLine Daily said the next phase for the sector will hinge less on proving demand and more on whether suppliers can turn expansion plans into shipments without losing yield, pricing discipline, or gross margin.
