EXFO FTB-5700 Single Ended Dispersion Analyzer for FTB-200 v2 - Manual (Page 34)

Setting Up the Single-Ended Dispersion Analyzer
28 FTB-5700
Setting PMD and CD Acquisition Parameters
PMD Fiber type Must be set to one of the following types:
³
Telecommunication: also known as strong coupling.
If you are working directly in the field, you will always
use this fiber type.
³
Polarization-Maintaining (PM): also known as weak
coupling. This type is rarely used and is required for
specific types of tests only.
Note: Traces taken with a particular fiber type
cannot be reanalyzed with a different fiber
type afterwards.
Analysis Range The analysis range is the value used to calculate the ITU
grid and the maximum value for the acquisition. The
analysis range can be different from the wavelength
measurement range.
Fiber with
aerial sections
If the fiber installations are, for example, between
buildings, or suspended to reach the intended location,
the movement created by wind or other outside elements
can affect the PMD measurement. Select this option to
compensate for such possible movements.
