About the EF-TRC (Encircled-Flux Test Reference Cords)

The CFP-MM and CFP-QUAD kits includes the EF-TRC (encircled
flux test reference cords), which have signal conditioners on the
cords. When you use the EF-TRCs with the CertiFiber Pro
multimode modules, your tester complies with IEC 61280-4-1, ISO/
IEC 14763-3, and TIA-526-14-B standards for encircled flux.
Measurements made with compliant equipment change less than
10 % for losses of 1 dB or more when you make them at different
times or with different equipment that is also compliant.
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 106.

Put protective caps on all connectors when you do
not use them.
