High Resolution

LUNA OBR 4600 belongs to the Optical Backscatter Reflectometer product line. It is designed for testing and troubleshooting optical components and short network sections. The OBR 4600 offers ultra-high resolution and sensitivity to backscatter. With a spatial resolution of 10 µm and zero dead zone, the OBR delivers the highest-quality fiber diagnostics.

Temperature and strain measurements:

As an OBR, LUNA includes software for temperature and strain measurements, thanks to which it turns a standard telecom fiber into a high-resolution strain and temperature sensor.

The OBR uses the swept-wavelength interferometry (SWI) method to measure Rayleigh scatter. An external stimulus (strain or a temperature change) causes temporary changes (a shift) in the spectrum. The OBR evaluates the shifts and rescaling during measurements. The SWI method enables robust and practical temperature and strain measurement in fiber up to 70 m long with an accuracy of 1 µm or 0.1˚C.

The OBR was designed to offer the ability to examine optical networks and assemblies with a combination of spatial resolution, sensitivity and distance that is currently not possible with other instruments such as OTDR. The LUNA OBR makes it possible to troubleshoot, verify fault locations point by point, and characterize insertion and return loss individually. A simple way to measure and distinguish splices, connectors, bends and couplers.
