Analyzing Traces and Events
MAX-700 137
Viewing and Modifying Current Trace Settings
Span ORL: ORL calculated either between the span start and the span
end, or on the total fiber span, depending on the option you have
selected in the Setup window.
High resolution: High-resolution feature was selected to perform the
acquisition. For more information, see Enabling the High-Resolution
Feature on page 66.
Helix factor: Helix for the displayed trace. If you modify this
parameter, the trace distance measurements will be adjusted.
IOR: Refraction index of the displayed trace, also known as group
index. If you modify this parameter, the distance measurements for the
trace will be adjusted. You can enter an IOR value directly or let the
application calculate it with the distance between span start and span
end you provide. The IOR value is displayed with six digits after the
decimal point.
Backscatter: Rayleigh backscatter coefficient setting of the displayed
trace. If you modify this parameter, the reflectance and ORL
measurements for the trace will be adjusted.
Splice detection: Current setting for detecting small non-reflective
events during trace analysis.
Refl. detection: Current setting for detecting small reflective events
during trace analysis.
End-of-fiber det.: Current setting for detecting important event loss
that could compromise signal transmission during trace analysis.
