SEDI-ATI has designed rugged avionic fiber-optic cables that meet the aeronautic constraints. Indeed, in aircraft, there are space and weight restrictions. 5-µm OM3 or bend-optimized single-mode versions. Avioptics® Fiber Optic Cable built around our standard HCS® 200-µm Optical Fiber used in aircraft radio systems for years. µlinx® (micro-links) avionics fiber optic cable. Optimized for mission-critical reliability and flexibility, AirBorn Fiber Optic Copper Solution (FOCuS) Active Optical Cables are expertly engineered for aerospace, defense and space environments, supporting both copper and fiber solutions. Today, we continue to build on this esteemed heritage by leveraging decades of knowledge and expertise to provide. Lower Signal Loss. Copper cables have a signal loss that increases over distance. Fiber optic losses are present but at a much lower level.
