The numbers
What it is
Finished optical products: cloud optical modules that plug into data-center switches, optical circuit switches and industrial lasers. Systems revenue is reported as one product category alongside Components.
Why it matters to the stock. Cloud optical modules are the piece of Lumentum most directly tied to hyperscale AI cluster build-outs, and Systems revenue is where the 1.6T transition shows up first.
