What it sells6

High-speed optical transceivers
Devices that convert data signals to and from light so servers, switches and other network equipment can communicate over fiber.
Laser chips, assemblies and optical components
Parts that generate or detect light for data-center connections and other fiber-optic networks.
Optical circuit switches
Equipment that connects fiber-optic paths in data centers, allowing data to be routed between devices.

Show 3 more

Optical transport equipment
Equipment including reconfigurable optical add-drop multiplexers, amplifiers and signal monitors that route and strengthen light signals in communications networks.
Industrial lasers
Fiber, solid-state and ultrafast lasers used for cutting, welding, drilling and other precise material-processing work.
Laser light sources for three-dimensional sensing
Lasers used in sensing systems in smartphones, computers and other consumer electronics.

Who buys it6

Cloud and artificial-intelligence data-center operators buy optical components and transceivers for links between servers, switches and other equipment.
Artificial-intelligence infrastructure providers buy optical parts and systems for connections within and between data centers.
Network equipment manufacturers buy components and subsystems to build their own communications equipment.

Show 3 more

Communications service providers buy products for local, city-wide, long-distance and undersea fiber-optic networks.
Industrial equipment makers buy lasers used in manufacturing processes such as metal cutting, semiconductor processing and battery production.
Two individual customers accounted for 26.6% and 15.0% of revenue, respectively (fiscal year ended June 27, 2026, high).

What it stands on, and what could break it

What the business leans on

1Revenue is concentrated among a small number of customers: two individual customers accounted for 26.6% and 15.0%, respectively (fiscal year ended June 27, 2026, high).
2Some materials, packages and components have only one or a limited number of suppliers, and replacements may not be available quickly or at acceptable cost.
3The company relies on contract manufacturers as well as its own factories, and must expand or adjust production to keep up with changing customer orders.

What could go wrong

1A small number of customers account for a large share of sales, many customers do not promise to buy a set amount, and sales to a previously significant customer have been restricted.
2Shortages of components and reliance on limited-source suppliers or contract manufacturers can delay production, raise costs or prevent the company from meeting customer demand.
3Tariffs, export controls and other trade restrictions can raise manufacturing costs, limit sales to some customers or regions, and disrupt access to components.
