Components (laser chips and sub-assemblies)
Largest line at $2.0 billion of fiscal 2026 revenue, up about 80% from fiscal 2025.
The numbers
What it is
Semiconductor laser chips, laser sub-assemblies, line subsystems and wavelength-management products. Optical module makers and network equipment companies buy them as the core building blocks of their products.
Why it matters to the stock. Components sit upstream of the whole company, so chip supply, yields and pricing drive gross margin and the stock's reaction to AI networking demand.
