What it does
Applied Opt designs and manufactures fibre-optic networking hardware, including optical modules, filters, lasers, transceivers and related transmission equipment. It sells these to internet data-centre operators, cable-television networks, telecom equipment makers and internet service providers. The company is based in Sugar Land, Texas.
Where it sits in the stack
In our index, the Rubin Build-Out 100, Applied Opt sits in Layer 5, Connectivity & Materials, within the High-Speed Interconnects sleeve — the optical hardware that links separate GPUs into a working cluster. It is a supplier to the data-centre and networking customers that build out that fabric, so its business tracks demand for cluster-to-cluster bandwidth rather than the chips themselves.
Who it is priced against
Closelook's peer group prices it against other optical-components and laser makers — Coherent, Lumentum, Fabrinet and Ciena — reflecting shared exposure to transceiver and laser demand rather than sector overlap alone.
