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.
