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.
