OTDR Setup: Pass/Fail Thresholds
Each column heading displays the wavelength to which the Pass/Fail Thresholds apply.
•
Splice loss (dB) - Non-Reflective Event Loss. The range for this parameter is 0.001 dB
to 9.99 dB in 0.001dB increments. For mated APC connectors, if there is no reflection,
the loss reports as Splice.
•
Connector Loss (dB) - Reflective Event Loss (connectors and mechanical splices).
The range for this parameter is 0.001 dB to 9.99 dB in 0.001 dB increments.
•
Reflectance (dB) - Events in the Event table exceeding the set Reflectance value. The
range for this parameter is -50.0 dB to -10.0 dB in 0.1 dB increments.
•
Attenuation (dB/km)
- Average Fiber Section Loss in dB/km that exceeds the set
value.
•
Total Loss (dB) - Total fiber loss in dB for Fiber-Under-Test (FUT) that exceeds the set
value.
• Total ORL (dB) - Total Optical Return Loss in dB for Fiber-Under-Test (FUT) that
exceeds the set value.
•
Fiber Length (km, miles) - Total fiber length that exceeds set value.
