SpaceRange
SEDI-ATI by Fiber Optics Group uses its expertise and know-how to develop a range of fiber components and assemblies dedicated to space applications.
For several decades, SEDI-ATI has been supporting the defense and aerospace sectors, where reliability is an absolute imperative. As recognized specialist in fiber-optic solutions for harsh and extreme environments, SEDI-ATI has used its expertise and know-how to create this compact and robust range that can withstand the most extreme conditions, such as mechanical shocks and vibrations, vacuum, and dynamic temperature variations.
The « space » range is composed of the 1×2 multimode coupler CP-X, the multimode multiplexer CP-MXS, the simplex 1.8 mm LTCX cable, and the connectors FCXtreme® and NANOXtreme®.
Ruggedized components
Examples of applications: The CP-X coupler can be used to split a laser signal into multiple channels toward different sensors. The CP-MXS multiplexer can be used to monitor the integrity of an opto-pyrotechnic line and to allow the laser-triggered detonation of an explosive charge (to separate the boosters of a launcher for instance).
CP-X and CP-MXS accept 50/125 µm or 62.5/125 µm graded index fibers, Low OH 105/125 µm step index fibers, as well as their acrylate high-temperature and radiation-resistant versions. They operate over a wide wavelength range (532-1625 nm) and are compatible with all types of optical connectors.
Cable for space
LTCX-1.8 mm cable has a loose tube structure. It is made of non-outgassing materials: a polymer tubing, a braid of Kevlar, and an ETFE coating. Kevlar plays a major role in the cable’s tensile strength. This cable absorbs expansion differentials caused by temperature variations. It is recommended for preserving the integrity of optical fiber in aerospace environments.
Specialty connectors
The FCXtreme® connector is an FC connector, more compact than standard FC connectors (length: 31 mm and OD < 10 mm). It has been qualified to be functional in shock and vibration conditions, and also under dynamic temperature variations from -55 °C to +125 °C, without affecting its performance. Ongoing space qualification.
The NANOXtreme® is a miniature optical connector (22.6 or 28 mm, depending on the version) designed for defense, aeronautics and space applications where high levels of performance, compact dimensions, and low weight are critical. The connector exists in 2 versions: with or without a mounting flange. Space qualification project is in progress.
SEDI-ATI is currently in the process of complying with the EN9100 standard.
