2 Set the Reference
2-1 Set the reference as described on page 24.
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, 1310/1550 nm, the reference
value must be better than -8.00 dBm (for example,
-7.50 dBm is a better value)
 For 9/125 μm fiber, 1490/1625 nm, the reference
value must be better than -4.00 dBm (for example,
-3.50 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
(Figure A-3,
 ).
3-2 Connect the cord you want test (Figure A-3,  ).
3-3 On the meter, press  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
wavelengths, press  until the wavelength LEDs
blink alternately. Or you may press  to switch
wavelengths as needed.
Note
If you are not using a SimpliFib
er 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,
 ), then repeat step 3-6.
