Customizing the Application

Selecting the Distance Units
Selecting the Distance Units
You can select the measurement units that will be used throughout the
application, except for certain values such as the pulse and the
wavelength. By convention, these values are always expressed in meters
(nanometers for the wavelengths).
The default distance units are the kilometers.
Note: If you select Kilometers (km) or Kilofeet (kf), m and f may appear instead
to display more precise measurements.
Note: The attenuation of fiber sections is always presented in dBs per kilometer
even if the distance units you selected are not the kilometers. This follows
the standards of the fiber-optic industry that provides the attenuation
values in dBs per kilometer.
