Chapter 10 Polarization Mode Dispersion Measurement
PMD Activation and self calibration
Fiber length
Unknown
Distance
The fiber length must be set to calculate the PMD coefficient.
Distance Unit
When the fiber length is manually entered, choose the distance unit
Km
Kfeet
Miles
Spectral Unit
Select Spectral unit: THz or nm.
If the softkey PMD is set to Standard mode, any measurement will be set to the strong
mode Coupling and the wavelength range to Auto.
The Expert mode is to be used with measurement through EDFA. When selected, the
Expert mode allows to define the coupling, to define if an amplified link is used and to
set the wavelength range.
Coupling
Strong
Weak
Amplified link
Select Yes when measuring through optical amplifiers
Measurement Band
Auto / C Band / L Band / C+ L Band / Manual
When Manual is selected, the Measurement Start and End must be set (in nm or THz
according to the unit defined in Spectral Unit parameter).
340
If you do not know the fiber length
Press Edit Number to enter fiber distance: Min=0.100 km /
Max=20000 km
Distance unit defined in kilometers.
Distance unit defined in kilofeet.
Distance unit defined in miles.
For standard singlemode fibers
For polarization-maintained fibers and components.
