Luna Technologies, a division of Luna Innovations Incorporated
(NASDAQ:LUNA), today announced the launch of the latest addition to
its Optical Backscatter Reflectometer™ product line, the OBR 4600.
The OBR 4600 product provides advanced diagnostic and inspection
capabilities to fiber optic manufacturers, developers, and
installers by offering ultra-high resolution, high sensitivity
measurements of optical fiber assemblies and networks up to 2
kilometers in length. The OBR 4600 instrument offers a substantial
increase in measurement speed over its predecessor as well as a new
“spot scan” option that enables the user to measure only a specific
area of interest on the fiber. The improved speed will open up new
opportunities for Luna’s distributed sensing capabilities.
Optical fiber networks and fiber-coupled assemblies are widely
used in applications ranging from telecommunications and commercial
and military avionics to medical catheters with integrated fiber
optic tools. The OBR 4600 instrument offers the ability to look
inside these networks and assemblies with a combination of spatial
resolution, sensitivity, and distance range that is not currently
possible with other instruments available today such as Optical
Time Domain Reflectometers (OTDR). With the OBR device, it is
possible to troubleshoot, inspect, and locate faults point by point
in an assembly and characterize the Return Loss and Insertion Loss
of each interface individually. With the sensitivity and resolution
of the OBR instrument, one can easily measure and distinguish
between a loss at a coupler, a splice, a bend, or a connector.
With the new version of the product, measurements can be taken
more than twice as fast in the normal mode of operation and over
ten times faster in the new fast scanning mode. With this
capability, 30 meters of fiber can be measured with 10 micron
spatial resolution in less than seven seconds. With the new “spot
scan” option users can troubleshoot and measure short segments of
fiber (1-2 meters) at repetition rates of up to 3 Hz.
In addition to troubleshooting, inspection and testing
capabilities, the OBR 4600 instrument also provides a tool for
fully distributed sensing using standard optical fiber as the
sensor. With its precise measurement of the Rayleigh scatter
reflected from the fiber, the OBR instrument can determine the
strain or temperature changes along the length of the fiber at any
point up to 70 meters in length with a spatial resolution as fine
as a few millimeters. Applications include load testing, structural
health monitoring, detection of structural defects in composites,
and distributed thermal monitoring.
Highlights of the OBR 4600 instrument include:
- Measure 30 m with 10 microns
resolution in less than 7 seconds
- Continuously measure a 1 m
segment at up to 3 Hz
- Easily locate, identify and
troubleshoot macro-bends, couplers, splices, connectors and
breaks
- Locate Insertion Loss points at
every point in the network or assembly – eliminate cut-back
- Look inside components to
evaluate each interface for RL and IL
- Test and troubleshoot short-run
networks (
