Luna - OBR 4600 - Optical Backscatter Reflectometer
-
Ultra-high resolution (10 μm sampling) reflectometer with “zero dead zone”.
-
Measure RL, IL, distributed loss, length, polarization states, phase derivative and group delay
-
80 dB dynamic range
-
Backscatter-level sensitivity (-130 dB)
The Luna OBR 4600 Optical Backscatter Reflectometer (OBR) is a powerful tool for testing and analyzing loss in short-run networks and components.
The OBR 4600 is an ultra-high resolution reflectometer that features a spatial sampling resolution of 10 microns, zero dead zone, and backscatter-level sensitivity. The OBR 4600 offers industry leading technology to precisely track loss and polarization states, allowing you to “see inside” your components and systems.
