Analyzing Results from the Results Table
The columns presented on the Results Table tab are detailed below. They
show you part of the data you need to know to analyze your results. The
content of the table can also be sorted for easier management. For
information on acquisition status (pass/fail)
³
The first column indicates if the data in this row is used to calculate the
final results.
³
Wavelength: indicates the wavelength at which the dispersion has
been calculated.
³
RGD: corresponds to the measured relative group delay.
³
Fitted RGD: corresponds to the relative group delay obtained from the
fitted curve over the measured RGD.
³
RGD Deviation: corresponds to the absolute value between the RGD
and the Fitted RGD.
³
Dispersion (ps/nm): Dispersion value when fiber length is unknown.
³
Dispersion (ps/nm-km): Coefficient of dispersion when fiber length is
known.
