About Applied Optoelectronics

AOI is a vertically integrated company with a state-of–the-art semiconductor component fab at our USA Headquarters near Houston, Texas. Coupled with an SMT production line at our China operation, a high degree of manufacturing integration enables us to deliver performance with fast lead times at a competitive cost. All of our manufacturing sites are TL9000:2016 & ISO9001:2015 certified.


AOI transceiver products feature AOI lasers with superior performance and excellent reliability. The transceivers are designed in and manufactured from our Taiwan Division. Each division of AOI has assembled a world-class pool of talent, from optoelectronics professionals, to mechanical engineers, RF and digital circuit designers, all with the goal of developing best-in-class products.

Broad product lines make AOI capable of extending its addressable market to more fiber optic applications. Equipped with excellent design capability, key in-house optical components, and volume manufacturing facilities, AOI is offering a uniquely high level of price competiveness and performance.

Applied Optoelectronics, Inc. (AOI) designs, develops, and manufactures advanced optical devices, packaged optical components, optical subsystems, laser transmitters, and fiber optic transceivers.

We are a leading provider of fiber‑optic networking products. We serve four growing end-markets: internet data centers (Data Center), Cable Television Broadband (CATV), fiber-to-the-home (FTTH), and telecommunications. We design and manufacture a range of optical communications products employing our vertical integration strategy from laser chips, components, subassemblies and modules to complete turn-key equipment. We design, manufacture and integrate our own analog and digital lasers using a proprietary Molecular Beam Epitaxy (MBE) fabrication process, which we believe is unique in our industry. The lasers we manufacture are proven to be reliable over time and highly tolerant of changes in temperature and humidity (delivering millions of hours service), making them well-suited to the CATV and FTTH markets where networking equipment is often installed outdoors.
