Luna Technologies' Optical Backscatter Reflectometer™ (OBR) delivers unprecedented inspection and diagnostic capabilities for the fiber optics industry.

Luna Technologies' Optical Backscatter Reflectometer™ (OBR) 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 will pinpoint even the smallest contributors to loss: bends, crimps, bad splices, you name it — we find it. The distributed sensing option provides even a more complete picture of what's happening in the system. Discover what you don't know about your component and what the Luna Technologies' OBR can do for you.


  • High resolution OTDR - Resolve individual features with spatial resolution down to 40 microns.
  • High sensitivity - 70 dB of dynamic range and -130 dB sensitivity.
  • Long range - Measure up to 2000 meters in length with a single connection, single scan.
  • Single Connection IL and RL - Measure insertion and return loss in a single scan.
  • Locate loss events - Monitor backscatter levels to isolate losses due to bends, crimps, bad splices, etc.
  • "Look inside" devices - Use powerful windowing feature to interrogate individual components within a subsystem.
  • Polarization Tracking - Track changes in the state-of-polarization as light propagates through an optical network.
  • Intuitive graphical interface - All key data and graphs in a simple, easy to use interface.
  • Distributed sensing - use standard optical fiber to monitor the changes in temperature and strain

Optical Backscatter Reflectometer: Model OBR 4400-The OBR 4400 uses swept-wavelength coherent interferometry to measure minute reflections (< 0.0003 parts per billion) in an optical system as a function of length with spatial resolution less than 10 microns.

OBR Software Packages
Software Developer Kit: Skew measurements can now be made on multimode and/or single-mode fiber cable ribbons using a combination of Luna Technologies' user-friendly Software Development Kit (SDK) in conjunction with the Optical Backscatter Reflectometer and the highly scalable Fiber Optic Switch Skew is determined by making a single-ended time-of-flight measurement of each fiber in a cable strand and computing the path differential, which is then graphically displayed to the user. This can all be achieved with the single click of a button with full measurement time less than 1 minute. With the same measurement, the user can use OBR software tools to characterize the dispersion of each fiber in the cable strand, thus reducing overall test time and the need for duplicating equipment.

Desktop Analysis : This software provides all the benefits of OBR analysis without the instrument. Save data files from your OBR measurements, share them with your customers, work on them from your desk or on vacation - anywhere that you have a computer with desktop analysis software!

Lightpath Analysis: Combined with ultra-high resolution OBR measurements, this software quickly verifies if an optical component or sub-assembly meets desired specifications. Eliminate your tedious testing and qualification of components using the Lightpath Analysis Software.

Distributed Temperature and Strain Measurements: Combined with Luna's Optical Backscatter Reflectometer, this software enables a standard telecom-grade fiber to become a distributed sensor. This measurement capability provides a practical and economical alternative to fiber Bragg gratings and extrinsic Fabry-Perot interferometric sensor in situations where a large number of closely spaced measurements are desired. Turn your existing fiber into a distributed sensing system.
