Fluke CertiFiber Pro User Manual page 55

The IEC 61280-4-1, ISO/IEC 14763-3, and
TIA-526-14-B standards require your optical loss
test set to comply with encircled flux standards at
850 nm with 50 µm/125 µm fiber. The standards
recommend compliance at 850 nm with 62.5 µm/
125 µm fiber and at 1300 nm with 50 µm/125 µm
and 62.5 µm/125 µm fiber.
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 14.
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.
