2 Set the Reference
2-1 Set the reference as described on page 26.
2-2 Make sure that the reference value is good:
•
For 50/125 µm fiber, the reference value must be
better than -24.50 dBm (for example, -23.50 dBm is a
better value)
•
For 62.5/125 µm fiber, the reference value must be
better than -20.00 dBm (for example, -19.50 dBm is a
better value)
•
For 9/125 µm fiber, the reference value must be
better than -8.00 dBm (for example, -7.50 dBm is a
better value)
If the value is not good, do the reference procedure
again with a different test reference cord.
3 Test the Cord in Both Directions
3-1 Disconnect the test reference cord from the meter
A
(Figure A-3, ).
3-2 Connect the cord you want test (Figure A-3,

until LOSS appears.
3-4 If the source's AUTO LED is not on, press
3-5 If you want the source to automatically switch
Z
wavelengths, press
blink alternately. Or you may press
wavelengths as needed.
If you are not using a SimpliFiber Pro source, set
the source to the desired wavelength and to
continuous wave output. On the meter, press
to select the wavelength generated by the source.
3-6 Compare the loss measurement to these limits:
•
Multimode test reference cord: 0.10 dB or less
•
Singlemode test reference cord: 0.20 dB or less
If the connectors show no contamination or damage,
but the loss is higher than these limits, the cord does
not comply with ISO/IEC 14763-3. Do not use the cord
as a test reference cord.
3-7 Connect the cord in the opposite direction (Figure A-3,
C
), then repeat step 3-6.
