10) Enter the fiber length in meters. If entering the length in feet is preferred,
press to toggle the length units to FEET.
NOTE: if the FiberMeter has the optional installed light source, the length will
already be entered into this field.
11) Press to continue.
Once the fiber length has been acquired, remove the patch cords from both ends of the link if necessary.
12) Enter the number of connections in the link, and press to continue.
NOTE: an inline connection is the junction where two fiber connector endfaces
meet, such as in a patch panel or bulkhead adapter. For example, if the link under
test is installed into patch panels, then the number of connections to be entered
would be ‘2’.
13) Enter the number of splices in the link, and press to continue. Splices
can be either fusion or mechanical.
®
NOTE: some pre-polished connectors, such as the Unicam , use mechanical
splice technology for fiber termination. These connectors should be counted as
splices when running the FiberMeter Link Wizard.
14) Connect the light source to the detector port on the FiberMeter using
a patch cord that matches the fiber type of the cable under test.
NOTE FOR MULTIMODE SOURCES ONLY: multimode reference jumpers need
to be wrapped around a mandrel, which is simply a cylinder of a specific size.
Mandrels are used to filter out excess modes of light in order to achieve
Equilibrium Mode Distribution (EMD), a requirement of test procedures based on
national and international cabling standards. See the table below for mandrel size information.
15) Power on the light source and set it to the wavelength shown on the FiberMeter display. Allow the
source to warm up according to manufacturer’s specifications.
NOTE: only wavelengths that are supported by the chosen cabling standard will appear on the screen during
the LINK WIZARD.
16) Press to continue.
