SEDI-ATI Fibres Optiques

SEDI Fibres Optiques offers a unique range of special multimode fiber-optic assemblies for extreme environments: hermetic feedthroughs, spectroscopy bundles arrays and octopus, couplers, WDMs, specialty optical fiber patch cords and connectors, medical probes, and fiber spools for ROVs and UGVs.

Since 1951, our mission is to design and build turn-key solutions to enable our customers to bring light in any environment, whatever their constraints are!

SEDI-ATI is specialized in custom optical fiber components and solutions for extreme environments such as extremely high and low temperatures, extreme pressures from ultra-high-vacuum to hyperbare, and radiative, corrosive or abrasive environments.

We offer achromatic MM couplers & WDMs, pressure & vacuum hermetic feedthroughs, bundles & arrays, patchcords & connectors, and medical probes.

We have a strong expertise in choosing the right fiber together with the right materials, coatings, buffers, and special ingredients to achieve fiber assemblies that can handle stringent environmental constraints.

We address complex applications for many different markets. Our fiber assemblies are used in applications in extremely aggressive and hazardous environments such as those found in the oil and gas industry, in nuclear plants, in electric utilities, or in the marine for instance. The applications of our products and solutions are as diverse as opto-pyrotechnics, cryogenics, or high-power lasers that can cut and weld steel.

Besides SEDI-ATI Fibres Optiques is the exclusive distributor of the companies OFS Specialty Photonics and Gould Fiber Optics.
