A fresh wave of buying hit optical infrastructure stocks after Corning $GLW ( ▲ 3.14% ) announced a massive fiber-optic supply deal with Meta $META ( ▲ 1.46% ) . The agreement is reviving a once-hot AI infrastructure trade that had cooled in recent weeks.
AI data centers need more than chips
Corning’s $6 billion deal to supply fiber connections for Meta’s AI data centers highlights a key reality of the AI boom: it is not just about GPUs. Massive clusters of servers need high-speed optical cables, connectors, and components to move data quickly and efficiently.
That spending signal lifted other companies that make similar hardware. Shares of Amphenol $APH ( ▼ 6.07% ) , Coherent $COHR ( ▲ 13.58% ) , and Lumentum $LITE ( ▲ 8.05% ) all surged as investors rotated back into the optical networking theme.
A trade getting its groove back
These stocks were market darlings in the second half of last year, riding enthusiasm around AI infrastructure buildouts. But momentum faded in December as investors took profits and questioned how long the spending surge could last.
Meta’s willingness to commit billions to optical gear suggests that demand for data center connectivity remains strong. For now, the deal has reminded investors that the AI buildout extends far beyond semiconductors, giving optical suppliers another moment in the spotlight.
