OBR 6200 Series
Portable Optical Backscatter Reflectometers
The Luna OBR 6200 Series is a new line of portable and rugged
ultra-high resolution reectometers with backscatter-level
sensitivity for testing ber optic networks deployed in aerospace,
naval, data center and industrial applications.
The OBR 6200 Series utilizes optical frequency domain
reectometry (OFDR) technology to measure distributed return loss
(RL) and insertion loss (IL) with sub-millimeter spatial resolution,
high precision and high dynamic range. The OBR 6200 is a rugged
battery powered integrated system with an intuitive touchscreen
user interface, making it ideal for eld maintenance applications.
The OBR 6225 models are ideal for short ber optic networks found
in aerospace, naval, transportation and industrial applications.
KEY FEATURES
APPLICATIONS
• Fully portable and rugged OBR
• Track and analyze return loss (RL)
and insertion loss (IL) versus length
• Spatial sampling resolution down
to 80 μm
• Detect and precisely locate
reective events
• Measure optical path length with
high precision
• Automatic event detection
• One or two optical channels
• Available with IP65 and MIL-STD
certications
• Troubleshoot ber assemblies in
the eld
• Precisely locate IL sites, high RL
connections, ber breaks, etc.
• Maintain avionics, aerospace,
naval and industrial networks
• Verify ber lengths of data center
interconnects
• Troubleshoot ber optic sensing
systems
Portable high-resolution reectometry for
eld and maintenance applications
The OBR 6225 maps reflection versus length with high resolution, automatically detecting
RL reflection events and IL sites that exceed user defined thresholds
