OBR 4610
Optical Backscatter Reflectometer
TM
The Luna OBR 4610 extends Luna’s award winning Optical
Backscatter Reectometer
TM
technology to 1060 nm applications.
Designed for component and short optical network testing and
troubleshooting, the OBR 4610 delivers ultra-high resolution
reectometry with backscatter-level sensitivity. With sampling
resolution as low as 10 microns, zero dead zone, an extremely
low noise oor, the OBR 4610 allows you to “see inside” your
components and systems and map reection loss along the entire
length of the optical path. Backscatter-level sensitivity allows
distributed IL measurements as well. The OBR 4610 provides
spectral analysis of the optical path and phase measurements.
KEY FEATURES
APPLICATIONS
Use convenient cursor tools to measure and examine scatter level and reflection
events to measure RL and IL for closely spaced events.
