Benchtop Optical Backscatter Reflectometer (OBR 4400)


Luna Technologies

The OBR™ 4400 is the industry's only ultra-high resolution OTDR with Raleigh backscatter-level sensitivity (better than -130 dB) designed for precision analysis of fiber optic components, optical modules and optical sub-assemblies.

Luna's patented optical frequency domain reflectometer (OFDR) technology implemented in the OBR™ analyses fibre optic assemblies and components with a level of speed, accuracy and repeatability unmatched by any other fibre optic testing solution on the market today. The OBR™ 4400 functions as a Zero dead zone OTDR reflectometer and can locate events such as macro-bends, splices, air gaps, micro cracks, and other optical defects and anomalies with micrometer event resolution on devices up to 70 metres in length.

A small, easily transportable platform coupled with an intuitive interface add to the OBR™ 4400's overall utility. The instrument automatically adjusts for varying device lengths and requires no special setup or jumpers. In addition, calibration is automatic and is referenced to an internal NIST traceable HCN cell to ensure years of reliable, accurate and repeatable service. The OBR™ 4400 also supports precision length and skew measurements for cable assemblies as well as distributed temperature and strain sensing using standard optical fibres.

Model Description
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 fibre to become a distributed sensor. This measurement capability provides a practical and economical alternative to Fibre Bragg Gratings and extrinsic Fabry-Perot interferometric sensors in situations where a large number of closely spaced measurements are desired. Turn your existing fibre into a distributed sensing system!

NEW Portable Optical Backscatter Reflectometer (OBR 4200)

Luna Technologies' Optical Backscatter Reflectometer™ (OBR) 4200 is the industry's only portable, ultra-high resolution reflectometer with backscatter-level sensitivity designed to test short networks. In a small, rugged, easily transportable platform, the OBR 4200 provides the capability to "see" any event in a fiber assembly or network out to 500 meters with no dead-zone and millimetre resolution. With industry-leading sensitivity and resolution in a portable platform, the OBR 4200 is the ultimate tool for manufacturing and on-site inspection and troubleshooting of your fibre optic network.
