OBR 6225
Portable Optical Backscatter Reflectometer
The Luna OBR 6225 is a portable and rugged ultra-high resolution
reectometer with backscatter-level sensitivity for testing ber
optic networks deployed in aerospace, naval, data center and
industrial applications.
The OBR 6225, along with the OBR 6235 for data centers and longer
networks, are part of the OBR 6200 Series for precision testing of
short and medium length ber optic links and assemblies.
The OBR 6200 Series systems utilize optical frequency domain
reectometry (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 6225 is a rugged
battery powered integrated system with an intuitive touchscreen
user interface, making it ideal for eld maintenance 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
reective events
• Measure optical path length with
high precision
• Automatic event detection
• One or two optical channels
• Available with IP65 and MIL-STD
certications
• 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
The OBR 6200 Series provides portable
high-resolution reectometry 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

NOTES
1. With Extended Length Option available for the OBR 6225
2. Distance between two sample points in SMF-28.
3. Range between strongest reflection greater than -60 dB and noise floor.
4. Noise floor return loss at half of maximum length.
5. Measured with 1 cm integration width.
6. Two way loss before backscatter reaches noise floor and IL measurements
are no longer possible.
7. Measured with integration widths of 10 cm, 12.5 cm, 25 cm and 50 cm for
20 m, 50 m, 100 m and 200 m modes, respectively.
