OBR 5T-50
Optical Backscatter Reflectometer
TM
The OBR 5T-50 is a fast, simple-to-use and low-cost
precision reectometer that measures the Insertion Loss (IL) and
Return Loss (RL) distribution of passive optical components and
modules including PLCs, optical cables, connectors, switches,
couplers and more.
This instrument utilizes swept-wavelength interferometry to
measure backscattered light as a function of distance with -125
dB sensitivity and 20 micron sampling resolution. The OBR 5T-50
reduces cost and complexity while increasing test throughput by
measuring RL, IL and length with a single instrument.
KEY FEATURES
APPLICATIONS
Return Loss vs. length measurement of a MEMS-based optical switch. The first
two reflections are 5.0 mm apart. This measurement was recorded with 20 micron
sampling resolution.
Industry-leading combination

NOTES
1. Distance between two sample points along the length
axis in SMF-28.
2. Accuracy is guaranteed via internal NIST-traceable
HCN gas cell.
3. Range between strongest reflection greater than -30
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 10 cm integration width.
