Lumentum and Coherent Stocks Rise as Nvidia Pushes Optical Networking for AI
Nvidia's CEO stressed the need for optical networking in AI data centers, lifting optical component makers Lumentum and Coherent.
What Nvidia's Optics Comments Changed for LITE and COHR
Nvidia's chief executive publicly emphasized the need for optical connections, rather than only copper wiring, to link chips inside next-generation AI data centers, and the comments lifted shares of two of the biggest suppliers of that optical gear. Lumentum and Coherent Corp. both make the optical transceivers and components that convert electrical signals into light so data can travel faster and over longer distances between servers, which becomes more important as AI clusters grow larger and hungrier for bandwidth.
Why Lumentum and Coherent Stocks Are in Focus
As AI data centers scale toward hundreds of thousands of connected chips, copper cabling runs into physical limits on speed and distance, pushing more of the network toward optical connections. Nvidia's own comments function as a demand signal for that shift, since Nvidia's networking and system designs increasingly determine what components server makers and hyperscalers need to buy. When Nvidia's leadership frames optics as a near-must rather than an option, it reinforces the case that Lumentum and Coherent sit in a structurally growing part of the AI buildout, not just a cyclical one.
Which Stocks, and Why
Lumentum and Coherent are the two companies from this item's SYMBOL LIST with a direct stake, since both were named as beneficiaries of the same comments. Both supply optical components used in data-center networking, and stronger demand for optical gear tends to support pricing and volume for both companies at once rather than favoring one over the other. Nvidia itself is the source of the comments rather than a company whose own results move on this specific story.
What to Watch
The clearest confirmation will come from Lumentum's and Coherent's own order books and revenue guidance in upcoming earnings reports, particularly any commentary on data-center and AI-related optical component demand. Capital-spending updates from the large hyperscalers building AI data centers are another signal worth tracking, since their capex plans ultimately determine how much optical gear gets ordered.

Frequently asked questions
Why did Lumentum and Coherent shares react to Nvidia's comments?
Nvidia's CEO said optical connections are increasingly necessary in AI data centers, which reinforces demand for the components these two companies supply.
What do Lumentum and Coherent actually make?
Both make optical transceivers and components that convert electrical signals to light for faster, longer-distance data transmission inside data centers.
Is this a one-time boost or a longer trend?
The comments point to a structural shift toward optical networking as AI data centers scale, which is a multi-year trend rather than a single event.
