4. Test the Cord in Both Directions
4-1 Disconnect the test reference cord from the INPUT port
of the tester (Figure A-4, A ).
4-2 Connect the cord you want test (Figure A-4, B ).
4-3 Turn the rotary switch to AUTOTEST, then press P.
This test measures the loss of connector shown in
Figure A-4.
4-4 When the first part of the test is completed, connect
the cord in the opposite direction (Figure A-4, C ).
4-5 Press KOK. This test measures the loss of connector
shown in Figure A-4.
5. Read the Loss Measurements
Compare the loss measurement for each direction 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.
