An article in Defense Tech Briefs magazine by Luna Innovations, "Fiber Interferometry for Testing Military Avionics," discusses the use of Optical Frequency Domain Reflectometry as a health diagnostic tool for military and aerospace fiber networks. Traditionally, fiber optic networks are inspected with instrumentation based on optical time domain reflectometry (OTDR). The article discusses the development of modern fiber optic networks and the use of Optical Frequency Domain Reflectometry (OFDR) as a health diagnostic tool for military and aerospace fiber networks. Luna's proprietary OFDR technology is key in Luna's Optical Backscatter ReflectometerTM (OBR) platform. The OBR 4400 is an ultra-high resolution OFDR with backscatter-level sensitivity designed for component- and module-level reflectometry.
