APPLICATIONS:
VOLT stands for Visual Optical Length Tester, and offers a unique,
low-cost alternative for users who need to measure the length of
optical fibers.
Fiber installations are increasingly required to have fiber length
measurements to comply with bid requirements. Rather than
purchase certification test sets that can cost thousands of dollars, the
VOLT can be added to an installerÂ’s existing fiber test kit.
These length testers use a “round-robin” method of measuring fiber
length. This is accomplished by looping back two fibers at one end of
the fiber run with a patch cord. The round trip time that the light takes
to travel through both fibers is converted to length in kilometers, then
divided by two to show the length of the fiber cable. There is no need
to measure the length of all the fibers; the length measurement can
be applied to all fibers in the cable. This method of length testing
provides accurate measurements, and saves time and money.
Measuring fiber by the jacket is an accepted method of
measurement; however, there are many scenarios where this may
not be valid. Length markings may be hard to reach if they are
already terminated in a patch panel. Fiber links may also go through
multiple cross-connects or have splices in the middle, thereby
making jacket markings invalid. Optical measurement of fiber
produces accurate results without the need for jacket markings.
Optical measurement also saves time by eliminating the need to
estimate the length of the fiber run with a measuring wheel. This
method is especially troublesome and inaccurate in networks that
traverse walls, are in a star topology, or contain riser cables.
The VOLT uses a visible laser that can measure fiber links of up to 1.5
kilometers, and is accurate to within ±2.5 meters. In addition to
length testing, the VOLTÂ’s high-intensity laser permits it to do double
duty as a visual fault locator, and a pulsing mode allows for easy fiber
identification.
