Using fiber optics for the defense and aerospace sectors

The defense and aerospace sectors were among the very first to adopt optical fiber technologies mainly because of their very light weight and immunity to electromagnetic interference. If it was originally for telecommunications, it is today more and more for sensing. SEDI-ATI has developed a wide range of optical fiber components and fiber optic assemblies able to withstand extreme environments met in a variety of air, sea, ground, and space applications.
