Analyzing Traces with the Bidirectional Analysis Application
214 FTB-7000 Series
Viewing Results
Information specific to the A->B or B->A trace is also displayed:
³ Range: Acquisition range.
³ Duration: Duration of the acquisition.
³ 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.
³ High resolution: Indicates whether or not the acquisitions were
performed using the high-resolution feature.
³ IOR: Index of refraction of the displayed trace.
³ Backscatter: Rayleigh backscatter coefficient of the displayed trace.
³ Helix factor: Helix factor setting of the displayed trace.
³ Splice loss detection: Splice loss threshold for detecting small
non-reflective events during trace analysis.
³ Reflectance detection: Reflectance threshold for detecting small
reflective events during trace analysis.
³ End-of-fiber detection: End-of-fiber threshold for detecting important
event loss, which could compromise signal transmission, during trace
analysis.
