TRC VERIFICATION
. The tester measures and saves the loss
of the test reference cords you added. The IDs for these results
start with “TRC”, show the date and time of the test, and have
an for the test result.
The tester shows a warning if the loss of a TRC is more than
these limits:

Maximum loss for multimode TRCs
: 0.15 dB

Maximum loss for singlemode TRCs
: 0.25 dB
If the tester shows a warning, clean and inspect the
connectors on the TRCs in the path that has too much loss,
make sure the cords are straight as shown in Figure 111,
then do the TRC verification again.
