COHR's role in the buildout
Coherent sits in the Networking & Optics layer, supplying the light-speed links AI clusters run on. Every large training cluster needs optical transceivers to connect GPUs across racks, and Coherent's 800G datacom optics serve exactly that need, making AI datacom its dominant growth engine and the core of the thesis. Sizable telecom, industrial laser, and materials businesses sit alongside it. Supercycle scores its exposure as high, anchored by AI cluster interconnect demand.
LITE's role in the buildout
Lumentum sits in the Networking & Optics layer of the AI buildout. AI clusters move staggering amounts of data between chips, and its lasers and 800G transceivers are part of the optical plumbing that carries it, sold primarily to hyperscalers and cloud builders. Datacom optics for AI clusters is now the dominant growth engine of the company, offsetting weaker telecom and consumer 3D sensing demand, which is why its exposure to the buildout runs high.
Both stocks sit in Networking & Optics, so they compete for the same slice of AI spending.
