SEDI-ATI

SEDI-ATI is a French company within Fiber Optics Group that designs and manufactures custom passive fiber-optic components and assemblies. Its products are made for demanding applications and can be tailored to complex or extreme environments, including vacuum, pressure, cryogenic temperatures, high heat, corrosion, radiation, and mechanical stress.

The company serves defense, aerospace, industrial, medical, energy, and data-communications markets. Its range includes fiber-optic bundles, arrays and probes; specialty cables and patchcords; optical connectors and adapters; multimode couplers and wavelength-division multiplexers; and hermetic feedthroughs for vacuum and pressure systems. SEDI-ATI also produces disposable deployable fiber-optic spools for tethered unmanned ground, underwater, and aerial vehicles, as well as fiber-optic needles and products for spectroscopy, sensing, and medical applications.

Alongside custom design and manufacturing, SEDI-ATI offers related connection and inspection accessories, including optical viewers, connector cleaners, and fiber-inspection tools. The company works with customers to develop solutions where standard products may not meet specific environmental or technical requirements.
