Case study

Avionic embedded fiber optic links

Introducing optical fibers in aeronautics environments is a non-trivial exercise. The systems inside aircrafts and helicopters must meet demanding requirements such as robustness, high-reliability, immunity to electromagnetic interference, compactness and lightness just to name a few.

SEDI-ATI has developed, demonstrated and integrated specific fiber optic assemblies with avionics grade fiber optic cables and connectors for both commercial and military aircraft and helicopter applications.

They withstand exposure to corrosive and other chemicals, including jet fuel, oil, solvents, and hydrolytic liquids. Besides, they handle shocks, vibrations and extreme temperatures. Finally, they demonstrate very low outgassing levels since they are exclusively made of stainless steel and ceramic parts.

Product focus

NANOXtreme® miniature connector for MIL-AERO applications

SEDI-ATI delivers a robust small form factor optical connector fully qualified for military and aeronautics applications where high levels of performance, compact dimensions, and low weight are critical.

It has successfully passed shocks, vibrations, and temperature qualifications.
It establishes a secure point-to-point optical connection as short as 36 mm in length and as small as 6 mm in diameter. As a result, it opens up a broad range of new opportunities to bring light in extremely complex and compact applications.

Key features

  • small form factor
  • ruggedized
  • versatile
  • zero outgassing materials
  • resistant to corrosion and high-temperatures
  • PC or APC polish
  • PM, SM or MM fibers up to 125 μm cladding

FCXtreme® connector for military and space-flight applications

SEDI-ATI releases a high-performance versatile and compact FC type connector, fully qualified for military and space-flight applications.

So far it has been qualified for operation under shocks and vibration conditions as well as under dynamic variations of the temperature from -55 °C to +125 °C. Undergoing stringent tests are also being led in seismic, nuclear and geophysics conditions up to +200 °C.

Its dimensions have been studied to meet the best solution in terms of bulk. Indeed, it is rather short with its 31 mm length and has an outer diameter smaller than 10 mm. As a result, it is smaller than conventional FC connectors, which opens up new perspectives of usage.

Key features

  • FC J.I.S. compatible
  • ruggedized
  • versatile
  • compact
  • zero outgassing materials
  • resistant to corrosion and high-temperatures
  • PC or APC polish
  • PM, SM or MM fibers up to 1000 μm core diameter
