An Optical Time Domain Reflectometer (OTDR) is a precision instrument used to locate events or faults along a fiber link, typically within an optical communications network. Distances are typically measured in kilometers and resolution is measured in cm.

Luna’s Optical Backscatter Reflectometer™ (OBR) is a precision optical reflectometer designed to analyze passive fiber optic components and photonic integrated circuits. It delivers unprecedented inspection and diagnostic capabilities for the fiber optics industry. Luna’s state-of-the-art OBR provides isolation of faults and problems well before final test, saving hours in rework and hard dollars in yield loss. Industry-leading 10 micron spatial resolution with zero dead-zone.
