Caution
To prevent damage to fiber connectors, to prevent
data loss, and to make sure that your test results are
as accurate as possible:
 Use the EF-TRC cords only with the CertiFiber Pro
modules or with sources approved by Fluke
Networks for use with the cords. If a source does
not have the correct LED and internal fibers, the
EF-TRC cords will not make launch conditions that
agree with encircled flux standards.
 When you use the EF-TRCs, DO NOT use other
mandrels.
 Always follow the handling guidelines given in
Figure 77.
 Put protective caps on all connectors when you do
not use them.
 Use EF-TRCs that have the fiber core dimension
(50 µm or 62. µm) and type of connectors (SC, ST, LC,
or FC) that are the same as the fiber link. Do not use
EF-TRCs with hybrid patch cords to connect to links
that have other types of connectors.
About Standard Mandrels
Standard mandrels make measurements of multimode power loss
more reliable than if you use no mandrels, but the measurements
do not comply with the standards for encircled flux. Fluke
Networks recommends that you always use only the EF-TRCs with
the CertiFiber Pro multimode modules so that your measurements
comply with EF standards.
If you must do tests in Far End Source mode with a different
multimode source, and the source is not approved by Fluke
Networks for use with the TRCs, use standard mandrels. Make
sure you use the size of mandrel that is correct for 50 µm or
62.5 µm fiber, and read all instructions for the source and
mandrel.
