Scale-up networking shifting copper-to-optics starting next year; Marvell scale-up optics outlook raised sharply, key driver of $1.5B FY28 raise
Matt Murphy· Marvell Technology· AI· 2026-08-31· about Marvell Technology (incl. Celestial AI CPO, NVIDIA NVLink Fusion partnership) (MRVL)
“Customers are aggressively planning scale-up optics deployment starting as early as next year... our fiscal 2028 revenue outlook for scale-up optics has increased meaningfully compared to prior expectations, positioning Marvell to be one of the largest enabler of NPO in AI infrastructure.”
Why it matters
First concrete timeline signal that scale-up (GPU-to-GPU) networks move to optics in calendar 2027 — a major TAM expansion beyond scale-out optics, with multiple architectures (NPO, CPO, MZM/EAM/MRM modulators) coexisting.
Investment implication
Read-through to optical component suppliers (Coherent, Lumentum, Fabrinet, TSMC silicon photonics) and suggests optical content per AI rack inflects in 2027; NVIDIA NVLink Fusion partnership confirms ecosystem alignment.
