•
Distance Unit – Sets metric for distance between fiber sections in viewing window (km,
kft, feet, meter, miles).
• Splitters – Defines splitter loss values to be applied when building the LinkMap.
Splitter Loss values
7.2.2 Pass/Fail Thresholds
Events exceeding the Pass/Fail Thresholds are highlighted in Red in the Event table. Different
Pass/Fail Thresholds values can be set for each test wavelength.
Event Loss (splice, connectors) and Reflectance threshold settings determine if a detected
anomaly should be reported and included in the event table including its event type (reflective
or non-reflective).
• Wavelength (nm) - Wavelength to which Pass/Fail Thresholds apply
•
Splice loss (dB)
- Non-Reflective Event Loss (fusion splices). The range for this
parameter is 0.10 dB to 9.99 dB in 0.01dB increments
•
Connector Loss (dB) - Reflective Event Loss (connectors and mechanical splices).
The range for this parameter is 0.10 dB to 9.99 dB in 0.01 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
•
Slope (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
•
Default Settings
: Resets Pass/Fail Thresholds to factory defaults
