SEDI-ATI offers a range of opto-pyrotechnics solutions for space applications

The products are perfectly integrated into all the critical stages of a space mission, guaranteeing optimum performance and rock-solid reliability.

Whether it is verifying the integrity of launchers, separating stages, detaching the fairing, or releasing satellites, these innovative products guarantee maximum precision and safety.

SEDI-ATI can meet the most demanding requirements of the space sector, thanks to its perfect command of advanced optical technologies and its ability to design customized solutions.

The ruggedized multiplexer accepts 105/125 µm core fibers with a numerical aperture of 0.22. The dichroic filter is customizable, and the product is compatible with any type of connector or optical contact. It is resistant to high-power pulses (30 W 12 ms).

The harness, single or multi-channel, can be ended with an ELIO contact (ou other), and by a MIL-DTL-38999 Serie III connector. Robust thanks to its stainless-steel protection, it withstands a full temperature range from -80 °C to +120 °C.

The optical detonator is customizable with its tailor-made dichroic filter. Whether in a light or reinforced version, it remains hermetically sealed after detonation. The mechanical parts and seals are defined according customer’s specifications.

SEDI-ATI Fibres Optiques, founded in 1972, designs, develops, and manufactures fiber-optic components and assemblies, such as multi-fiber assemblies, sealed feedthroughs, and fiber optic spools. More specifically, we design hardened and hermetically sealed reinforced solutions for space and opto-technical applications to specification. SEDI-ATI specializes in the complex and extreme environments of the defense, aeronautics, space, nuclear, and geophysics markets.
